The relevant situation is now reported as follows:

I. Overview of engineering projects and accident-related units

(A) the general situation of the project

In 2021, the water supply renovation project of Five Blessingg Hall Happiness Hospital in Laishan Township, Wuchuan County was built in 2016, involving 36 households with 72 people. When the project was completed, it shared a well with Dechangdian Village, built a new water tower, laid water distribution and household pipe network, and all houses were supplied with tap water, which has been running normally since the project was completed.

Since May 2021, Liu Qiongwen, deputy secretary of Laishan Township, Wuchuan County, and Wang Ermao, deputy director of Five Blessingg Tang Village Committee, have repeatedly called Fu Qiang, director of the County Water Affairs Bureau, and Zhang Junlin, head of the People’s and Livestock Drinking Office (hereinafter referred to as the "People’s Drinking Office") to report that the people in Happiness Hospital in Laishan Township have difficulty drinking water, and hope that the County Water Affairs Bureau can help solve the drinking problem of Happiness Hospital. After Zhang Junlin reported the situation to the County Water Affairs Bureau, the County Water Affairs Bureau regarded this project as a "practical project for the people On June 15th, 2021, a party meeting of the Bureau was held to study and decide to build a new deep well for the human drinking project of Five Blessingg Tangcun Mutual Aid Happiness Hospital in Laishan Township, and the human drinking office of the County Water Affairs Bureau was responsible for organizing the construction team.

In 2021, the water supply reconstruction project of Five Blessingg Hall Happiness Hospital in Laishan Township, Wuchuan County included a new water source well, a new well house, a new wellhead project, a 100-meter aqueduct, water pumps and other power facilities. The total investment of the project is 84,900 yuan.

(II) Construction unit: Wuchuan County Water Affairs Bureau.

In 2021, the water supply reconstruction project of Five Blessingg Hall Happiness Hospital in Haolaishan Township in Wuchuan County was studied by the party group of Wuchuan County Water Affairs Bureau, and the People’s Drinking Office of the County Water Affairs Bureau was responsible for the specific implementation. At the time of the incident, the People’s Drinking Office was an internal organization of the County Water Affairs Bureau and had no independent legal person qualification.

(III) Construction situation in the early stage of the project

On June 23, 2021, Zhang Jun Lin, head of the People’s Drinking Office of Wuchuan County Water Affairs Bureau, orally entrusted Zheng Yi (project construction leader, without construction qualification) to implement the water supply reconstruction project of Five Blessingg Hall Happiness Hospital in Laishan Township, Wuchuan County in 2021. Zheng Yi contacted Chen Jiarui, the legal representative of Wuchuan Chenyuan Well Industry Co., Ltd., who had been cooperating for a long time, to discuss well drilling, and then Wuchuan Chenyuan Well Industry Co., Ltd. dispatched a well drilling team to start well drilling on June 28 and July 3.

Second, the accident, emergency rescue and aftermath.

1. The accident happened.

On the basis of previous works, Zheng Yi and Li Wenhua (excavator drivers) excavated the trench along the water pipe on July 4th, and on July 5th, Zheng Yi hired two bridgehead workers to build inspection wells, and at the same time, Wang Linbiao and Zhang Erhong were employed to run the water pipe into the ditch. On July 6th, Wang Linbiao and Zhang Erhong were engaged in the pumping process (about 100 meters down), and Zheng Yi and the bridgehead workers continued to build inspection wells, and Wang Linbiao and Zhang Erhong finished pumping. At 8 o’clock on July 10th, Zheng Yi, the person in charge of on-site construction, led Li Wenhua (excavator driver), Wang Linbiao and Zhang Erhong to the construction site to continue their work. Zhang Erhong (who only wore safety helmet and did not take other protective measures) first went down the well to hang the wire rope and lift the pump. After the pump was lifted for about 10 meters, Zhang Erhong rose to the well, then sent electricity to pump water (the water was normal). After pumping for about 2 hours, he turned off the electricity and stopped the pump. Zheng Yi, the person in charge of on-site construction, found that the water was not clear enough, and decided to lower the water pump from about 90 meters in the well to about 110 meters (at this time, there were five people at the construction site, including Zheng Yi, Wang Linbiao, Zhang Erhong, excavator driver Li Wenhua and Wang Ermao, deputy director of Five Blessingg Hall Village Committee), and the construction worker Wang Linbiao (without taking any protective measures) went down to the well to prepare to lower the water pump. After Wang Linbiao went down to the bottom of the well, he immediately sat down against the well wall and the wellhead personnel shouted many times. At this point,Zhang Erhong mistakenly thought that Wang Linbiao had a heart attack and immediately went down to the well to rescue him (only wearing a helmet and taking no other protective measures). Zhang Erhong immediately squatted on Wang Linbiao’s body after going down the well. After Zheng Yi found the abnormality, he immediately prepared to go down to the well for rescue, which was discouraged by Li Wenhua. Later, Li Wenhua and Wang Ermao tied a rope to Zheng Yi’s body and tried to hang Zheng Yi with an excavator to enter the well for rescue. When Zheng Yi entered the wellhead about 1 meter, he suddenly felt unwell and immediately rose to the well, and the three people at the scene had to stop the rescue. After Zheng Yi rose to the well, he called the air compressor in turn, reported the situation to Zhang Junlin, and asked for rescue from 119 and 120. After the air compressor arrived at the scene, the air in the tap water inspection well was replaced. After the 119 and 120 people arrived at the scene, the 119 fire rescue officers and soldiers rescued Wang Linbiao and Zhang Erhong from the well. After being checked by 120 medical staff, they were declared dead.

The accident well depth is 3m.

Wellhead diameter is 800 mm.

The accident well is 1500mm in diameter.

Well diameter is 400 mm.

Well depth is 132m m.

2, the accident report.

After the accident, Zheng Yi, the person in charge of the on-site construction team, called 119 and 120 for rescue at 10: 25 and 10: 31 respectively. After receiving the alarm, the county fire rescue brigade informed the county emergency management bureau of the accident at 10: 35, and the main leaders and staff of the county emergency management bureau immediately rushed to the scene. After on-site verification, the county emergency management bureau reported the accident to the duty room of the municipal emergency management bureau and the duty room of the county people’s government at 12: 09 and 12: 10 respectively. Zheng Yi, the person in charge of the on-site construction team, telephoned Zhang Junlin, the person in charge of the People’s Drinking Office of the County Water Affairs Bureau, at 10: 20 on July 10th to report the accident at the construction site. After Zhang Junlin received the report, he telephoned Fu Qiang, the director of the County Water Affairs Bureau, and Fu Qiang and Zhang Jun Lin immediately set out at 11: 10 to participate in the disposal.

3, emergency rescue and on-site disposal

After the accident, Zheng Yi, the person in charge of on-site construction, called the air compressor in turn and asked 119 and 120 for rescue. After the air compressor arrived at the scene, it replaced the air in the tap water inspection well. At 10: 50, 119 fire rescue officers and soldiers arrived at the scene and carried out rescue. After on-site observation and understanding, two construction workers were in a coma in the tap water inspection well with a depth of three meters. There was an air supply pipeline with a steel cable and a water pipe in the well, and the air compressor had been supplying air to the well for more than 20 minutes. The scene was in an emergency, and the fire rescue commander immediately gave the order to carry out the rescue. The fire rescuers made safety protection, wore air respirator and wore safety ropes. With the assistance of other fire rescuers, they slowly entered the inspection well, and rescued two comatose people by using safety ropes in turn, and then handed them over to the ambulance personnel of the 120 emergency center at the scene for emergency treatment. After examination by medical staff, they were confirmed to have no vital signs and declared dead.

4, the aftermath.

On July 10th, Wuchuan County People’s Government took the initiative to intervene to appease family members and properly handle compensation matters. The leaders of Wuchuan County cooperated with the people’s government of Laishan Township and the heads of emergency and water affairs departments to express their condolences to the families of the deceased, expressed the concern and condolences of the county party committee and government, and held consultations on compensation. At present, compensation for the aftermath has been completed.

Three, the accident caused casualties and direct economic losses.

Two people were killed in the accident. The direct economic loss was RMB 2,229,300.

Four, the cause analysis and nature of the accident

(A) the direct cause

1. On the basis of the previous project, at 10 o’clock on July 10th, the oxygen content in the inspection well was about 1.0% due to the continuous pumping of water by the on-site pump for about 2 hours (relevant conclusions were drawn from three on-site gas detection tests after the incident by a third-party testing organization). At this time, two construction workers, Wang Linbiao and Zhang Erhong, rushed into the well to lower the water pump without wearing the necessary labor protection articles for working in a limited space, which eventually led to the death of two construction workers due to hypoxia and suffocation.

2. The construction site was not equipped with emergency rescue equipment and equipment that met the requirements. After the first construction worker went into a coma in the well, the second construction worker rushed into the well to rescue without wearing labor protection articles and emergency rescue equipment and equipment that met the requirements, resulting in an increase in the death toll.

(2) Indirect causes

1. The Wuchuan County Water Affairs Bureau contracted the water supply renovation project of Five Blessingg Hall Happiness Hospital in Laishan Township in Wuchuan County in 2021 to Zheng Yi, an individual who did not have the conditions for safe production and the corresponding qualifications, and as the competent department of the industry, he failed to perform the duties of safety production supervision, neglected the management of the construction process and failed to implement the duties of safety production supervision.

2. The on-site construction team organized by Zheng Yi, without business license and construction qualification, illegally contracted the water supply renovation project of Happiness House in Five Blessingg Hall, Laishan Township, Wuchuan County in 2021, and did not organize the construction in accordance with the relevant regulations on limited space operations during the construction process, which belongs to illegal contracting and illegal organization of construction operations.

3. Zheng Yi, the person in charge of the on-site construction team, failed to make safety technical disclosure to the employees before the operation and failed to formulate emergency measures, which led to the employees’ blind operation and blind rescue, which eventually led to accidents and an increase in the number of deaths.

4. The construction site lacks the necessary testing facilities for limited space operation. Before entering the limited space operation, the construction personnel failed to perform the examination and approval procedures according to the regulations on limited space operation management, and did not test the oxygen content and toxic and harmful gases in the operation well.

(3) Identification of the nature of the accident

After investigation, it was found that the "July 10" suffocation accident of Wuchuan County Water Affairs Bureau was a general production safety liability accident that violated the management of limited space operations.

Five, suggestions on the handling of the accident related responsible units and personnel.

(1) Persons who suggested to be exempted from accountability (2 persons)

1. Wang Linbiao, male, 62 years old, a construction worker, with weak safety awareness, rushed into the well to work without wearing the necessary labor protection articles for entering a limited space, which led to the accident. He was directly responsible for this accident, but in view of his death in the accident, it is suggested that he be exempted from being investigated for responsibility.

2. Zhang Erhong, male, 58 years old, is a construction worker with weak safety awareness. He rushed into the well to work and carry out rescue without wearing the necessary labor protection articles for entering a limited space, resulting in an increase in the number of casualties. He was directly responsible for this accident, but in view of his death in the accident, it is suggested that he be exempted from being investigated for responsibility.

(2) Persons who suggest to be investigated for criminal responsibility (1 person)

1. Zheng Yi, male, 58 years old, is the head of the on-site construction team. He has no business license and construction qualification. He illegally contracted the water supply renovation project of Happiness Hospital in Five Blessingg Hall, Laishan Township, Wuchuan County in 2021, and did not organize the construction in accordance with the relevant regulations on limited space operation during the construction process, which belongs to illegal contracting and illegal organization of construction operations. Before the operation, he did not make safety technical disclosure to employees and did not formulate emergency measures, resulting in blind operation and blind rescue of employees. In the end, it led to an accident and an increase in the number of deaths. He was mainly responsible for this accident and was suspected of constituting the crime of major liability accident. It is suggested that the judicial organs should investigate his criminal responsibility.

(3) persons who are recommended to be given disciplinary sanctions (3 persons)

1. Zhang Junlin, male, 45 years old, party member, head of the People’s Drinking Office of Wuchuan County Water Affairs Bureau, verbally entrusted the water supply renovation project of Five Blessingg Hall Happiness Hospital in Laishan Township, Wuchuan County in 2021 to Zheng Yi, an individual who did not have the construction qualification, and neglected the supervision during the implementation of the project, and was mainly responsible for this accident. It is suggested that the discipline inspection and supervision department give him disciplinary sanctions.

2. Tian Wenxiong, male, 58 years old, party member, member and deputy director of the Wuchuan County Water Affairs Bureau, attended the meeting of the bureau’s party group and agreed to organize the construction team to carry out the water supply renovation project of Five Blessingg Hall Happiness Hospital in Laishan Township, Wuchuan County in 2021. As the leader in charge of the bureau, he neglected the supervision of the construction project and the construction qualification of the construction team, and was responsible for the leadership in this accident.

As the main leader of the bureau, he neglected the supervision of the construction project and the construction qualification of the construction team, and took the leadership responsibility in this accident; And after receiving a phone call from Zhang Junlin to report the accident, Fu Qiang and Zhang Junlin rushed to the scene to participate in the disposal at the first time, resulting in their failure to report the accident to the county people’s government within the specified time, which was due to negligence and there was no subjective intention. It is suggested that the discipline inspection and supervision department give them disciplinary sanctions.

(4) Suggestions on the treatment of Wuchuan County People’s Government and Wuchuan County Water Affairs Bureau.

1. It is suggested that Wuchuan County People’s Government carry out county-wide informed criticism on Wuchuan County Water Affairs Bureau.

2. It is suggested that Wuchuan County Water Affairs Bureau be instructed to make a written inspection to Wuchuan County People’s Government.

3. It is suggested that the Hohhot Municipal People’s Government conduct a informed criticism for Wuchuan County People’s Government.

4. It is suggested that Wuchuan County People’s Government should be instructed to make a written inspection to Hohhot Safety Production Committee.

VI. Preventive Measures and Suggestions

In order to conscientiously sum up the lessons of the accident and prevent the recurrence of similar accidents, the following preventive and corrective measures are put forward:

1. Strengthen the safety management of construction projects, and compact the safety production responsibility of the participating enterprises. Wuchuan County Water Affairs Bureau must carry out the work of safety in production in strict accordance with the provisions of the Law of People’s Republic of China (PRC) on Safety in Production, that is, "safety must be managed in the industry, safety must be managed in the business and safety must be managed in the production and operation", and immediately carry out the work of "large-scale investigation and rectification" of production safety accidents of all construction projects participating units in the industry, establish "one enterprise and one file", and require all units to strictly implement the main responsibility of safety in production, strengthen safety management and strengthen risk awareness. Establish a ledger for the investigation and management of hidden dangers, establish and improve the safety production responsibility system and safety production rules and regulations for all employees, increase the investment guarantee for safety production funds, materials, technology and personnel, improve the level of safety production and ensure safety production.

2. Wuchuan County Water Affairs Bureau should further standardize the contract management of contractors. Units undertaking design, construction, supervision, installation and debugging must have corresponding qualifications. It is strictly forbidden to contract out production and operation projects, sites and equipment to units and individuals that do not have the conditions for safe production or corresponding qualifications, and resolutely put an end to the behavior of contracting projects without qualifications, linking or borrowing qualifications. Moreover, all parties involved in the construction should further standardize and perform the contract signing of construction projects and employees, and the contract must include relevant provisions on safety production management or sign a special safety management agreement.

3, strengthen safety education and training, strengthen the safety awareness of employees. Wuchuan County Water Affairs Bureau and all construction project contractors in the industry should immediately conduct safety training and education for employees through various forms and channels, establish and implement a safety training and education system, improve employees’ awareness and skills of accident prevention and disposal, and standardize employees’ safety production behavior.

4. Standardize the management of dangerous operations. Wuchuan County Water Affairs Bureau and all construction project contractors in the industry must formulate perfect safety production rules and regulations and operating procedures, strictly perform the examination and approval procedures for dangerous operations, arrange special personnel to supervise, inspect, guide and coordinate the whole process of the construction site, and equip the job site with necessary emergency rescue equipment, equipment and materials when carrying out hoisting, hot work, temporary electricity use, limited space and other dangerous operations specified by the emergency management department of the State Council in conjunction with relevant departments of the State Council in the future. The main person in charge, safety management personnel and special operations personnel shall hold relevant certificates.

5. Effectively improve the emergency response capability of enterprises. Wuchuan County Water Affairs Bureau should urge all enterprises in the industry to strengthen daily emergency training, improve the knowledge of accident prevention, hedging, escape, self-help and mutual rescue of employees, regularly carry out daily emergency rescue drills, improve the emergency handling skills of employees, and ensure that once an abnormal situation occurs, employees can effectively deal with it at the first time, so as to avoid the expansion of the situation or the occurrence of secondary accidents and minimize losses.

6, the implementation of comprehensive supervision responsibility for production safety. Wuchuan County Emergency Management Bureau should earnestly draw lessons from accidents, find weak links and regulatory loopholes, strengthen law and order, adhere to the "red line" of safety production, severely crack down on all kinds of illegal and illegal acts, and protect the health and life safety of the broad masses of people. It is necessary to improve the ability to perform their duties, guide various industries to strengthen safety management, and prevent production safety accidents.

7. All regions and relevant departments should "draw inferences from others", carry out in-depth publicity on the newly revised People’s Republic of China (PRC) Law on Work Safety and the Interim Provisions on Safety Management and Supervision of Limited Space Operation in Industry and Trade Industry (formerly Order No.59 of the State Administration of Work Safety) and other laws and regulations, and carry out special actions of "large-scale investigation and rectification" of hidden dangers in production in various industries and fields, so that enterprises and employees can know the law.

General production safety accident investigation team

"Don’t miss the blockbuster in 2007", "epic", "too violent" and "box office champion" …

　　All comments, even those negative ones, are attracting people to watch Sparta 300 Warriors. When I was ready to enjoy the shock and endure the blood, I saw the American version of Promise, which can also be called the American version of A Bloody Battle Caused by a Bag of Gold Coins.

　　The plot is not creative, it is straightforward from beginning to end, and it does not respect historical facts, but it does not exert any good imagination. The Persians bought off the priests with gold coins, so that the king could only lead 300 people to war, and also bought off the "parliamentarians", so that the warriors could not get support. The queen used her body as a price, but she was bitten by the "senator". In desperation, she took the knife and killed the senator. This knife not only ended the life of the bad guy, but also stabbed another bag of Persian gold coins on him, making the traitor active.

　　The above plot is the most turbulent part of the whole play, and it is also the most ridiculous part. The incomplete steamed bread in "The Promise" is still a technical error. This series of retarded plots can only be said that the screenwriter used all the raw materials wrong, and the director actually made a rotten meal.

　　In the bloody battle of 300 warriors, the only thing that can only be sensational is the father and son soldiers. If you can’t cheat the audience’s tears, at least let people choke for a second. It’s a pity that the heroic son died because of his father’s meaningless call. The big meal is rotten, and the side dishes are expired. This table of "feast" is appetizing.

　　In the play, the famous king could not get the support of the religious elders, but depended on his wife to sell himself. He failed to recruit the disabled Spartan and was defeated by both Scylla and Charybdis. He was nothing more than a brave man. Seeing him die at last only makes people feel logical and has no sense of bravery.

　　There is no plot to see the picture, which is our minimum requirement for domestic films. I didn’t expect Hollywood to make a "masterpiece" worse than domestic blockbusters, not to mention how ridiculous those "warriors" who are more developed than women are. In the film, The Lord of the Rings and The Lord of the Rings are everywhere. We don’t object to making an epic film with a magical shadow, but such petty theft is really shameful.

　　The only thing left to look forward to is "violence". From beginning to end, only a few heads have been cut off repeatedly, as stiff as a wax figure. There is no violence, it’s more like being stupid.

　　[PConline cross review]2019 is coming to an end. For the majority of DIYer, the first half of 19 years belongs to Intel；; In the second half of 19 years, it belonged to AMD.

In the first half of 2019:

　　Intel can still stably suppress AMD’s market share in the first half of the year only by relying on the toothpaste left by Skylake. It can be said that in the DIY market in the first half of the year, Intel still didn’t take AMD as an opponent.One thing said, Intel is really good at playing games.

In the second half of 2019:

　　The first two generations of Ruilong made AMD’s CPU department slightly better. In July, the three generations of Ruilong were AMD’s challenge to Intel:Don’t treat us like ants, the times have changed since today!

　　On the day of summing up at the end of this year, I will send you the annual popular A/I CPU cross-evaluation, which will be used as PConline’s 2019 CPU ranking.

　　This time, only the popular processors were selected as the horizontal selection. If you want to see a more complete ranking, you can click here to enter the 2019 CPU ladder diagram.

Six popular CPUs on e-commerce platform

　　This review is not in ceiling price. In recent years, in addition to the students who installed machines for cost performance, they also installed machines for the pursuit of ultimate performance. Therefore, the sales of high-end CPU are relatively high this year, which is of reference value for adding statistics. However, when the total score is evaluated horizontally, the price will still be added to the scoring item.

　　Based on the sales statistics of multi-e-commerce platforms, we selected six CPU models that sell well every year:

I. Intel i5-9600KF/　i5-9400F

　　“The middle-end main force that takes advantage of the right time and the right place."

　　The first place in sales volume is often occupied by Core i5, but this year’s Ruilong 3600X is also very competitive. In addition, the ninth generation Core i5 came out much earlier than the 3600X, and the accumulated sales volume is more reasonable than the latter.

　　Both CPUs are i5 of the ninth generation, and the sales volume is relatively hot. Here, I choose i5-9600KF as the representative of Intel.

Second, AMD Ryzen 5 3600X

　　"Sales champion in the second half of 2019"

　　During the period when the third-generation Ruilong CPU was just launched, apart from the eye-catching Ryzen 9 3900X and Ryzen 7 3700X, what attracted people more was the Ryzen 5 3600X with 6 cores and 12 threads. Everyone could count the boxes.

Iii. Intel i7-9700K

　　"The most cost-effective game artifact in the high end"

　　If you want to play games, you have to look at Intel. Compared with the situation that game optimization stopped at 4 cores a few years ago, the game’s support for 8-core CPU is not good now, but at least it has been done. Some large 3A masterpieces can really enjoy the performance bonus brought by multi-core, and Intel’s high-frequency and high-energy characteristics are very suitable for game scenes. Cutting the hyper-threading function that has zero effect on games, the i7-9700K is indeed the most cost-effective high-end CPU suitable for playing games this year.

Iv. AMD Ryzen 7 3800X/Ryzen 7 3700X

　　"showstopper that impacts the high-end CPU market"

　　It is also two high-end CPUs that big game players pay attention to, both of which are 8-core and 16-thread specifications. Ryzen 7 3800X can be regarded as a better Ryzen 7 3700X.

　　Although the game is not as good as i7-9700K and i9-9900K, the performance-price ratio and comprehensive performance are weighed together, and they are more worthy of purchase than two Intel high-end CPUs. Here, Ryzen 7 3800X, which is slightly stronger, is selected for comparative test.

V. AMD Ryzen 9 3900X

　　"miracle of 7nm, I/O die and glue MCM packaging"

　　In fact, in terms of miracles, its eldest brother Ryzen 9 3950X is more suitable, but because Ryzen 9 3950X keeps jumping tickets and has been in a "snap-up — — "Out of stock" status, as of the time of our statistics, we have not accumulated much sales, so we can’t be on the list.

　　The CPU of AM4 interface can be packed into 12 cores or even 16 cores, which is closely related to AMD’s newly designed core architecture. CCD+I/O die is more flexible than the big core route that Intel has always adhered to.

VI. Intel i9-9900KF

　　"Can it be used without exceeding 5GHz?"

　　Perhaps because i9-9900K is the flagship CPU launched at the end of 2018, itI lost to the low nuclear display version i9-9900KF.

　　After thinking about it, the value of this CPU should be that it will exceed 5GHz immediately after being bought back, and then it will be used to brush bilibili and visit Weibo, at least in the view of supercontinent. (Manual dog head)

▼Comparison of six CPU specifications: AMD is confident.

　　The CPU parameters are listed here. On the whole, the CPU specifications of AMD seem to be more bright: 7nm+ multi-core+super large three-buffer +PCIe 4.0, and the frequency span between different CPUs is not large. Intel dominates the high-frequency direction, and the frequency span between the mid-range and high-end CPU is large.

Test platform construction

　　Let’s introduce our evaluation platform first.

　　The hardware of the evaluation has been used all the time. The first thing to ensure is that the platform is stable and reliable.

　　As for the motherboard, both Z390 chipset and X570 chipset use ROG HERO series, with the same positioning, which reduces the performance impact caused by different motherboard specifications.

　　The radiator is GI-CX360 water-cooled with overclocking triple mirror. Because the specification span of CPU in this test is large, it will be safer to use 360 water-cooled.

　　The memory is pulled out from four Kiki royal halberds, and the combination of double 8GB is enough to give full play to their performance.

performance test

Theoretical performance test▼

　　The theoretical performance test project will test a variety of traditional running software, and whoever scores high will be powerful, simple and rude.

▍　CPU-Z v1.90

　　CPU-Z test items are divided into single-thread and multi-thread. It can be seen that i7-9700K and i9-9900KF with higher frequency have completely outperformed AMD’s three participating CPUs in single-thread performance, which should be a predictable result without testing.

　　In terms of multithreading performance, Ryzen 9 3900X has no suspense, and the 12-core 24-thread specification crushes the other five participating CPUs. Being both 8-core and 16-thread, Ryzen 7 3800X multi-threaded performance is higher than i9-9900KF with stronger single-core performance.

　　Ryzen 5 3600X with 6 cores and 12 threads is basically the same as i7-9700K with 8 cores and 8 threads, so i5-9600KF can only be a younger brother among them.

▍　CineBench R15

▍　CineBench R20

　　CineBench is a running score software that scores by testing the rendering speed. No matter whether this pile of CPU is in R15 or R20, the multi-thread performance ranking is the same. The multi-threaded performance of Ryzen 9 3900X still surpasses the other five CPUs, and in R20, the single-threaded performance of AMD processor actually surpasses the high-frequency i9-9900KF.

▍　wPrime 2.10 1024M

　　WPrime is a software that tests the computing power of CPU by calculating prime numbers, and it is also very direct and violent. The multi-core Ryzen 9 3900X is still popular, and the testing time is nearly half that of i9-9900KF. The slowest is i5-9600KF, because the number of core threads is relatively small, and Ryzen 5 3600X, which is located close to it, is much faster than it, only 60% of the time.

　　3DMark’s TSE project is also a software with multi-threading performance. Ryzen 9 3900X is still in the lead, while i9-9900KF with stronger high-frequency single-core performance is about 400 points away from Ryzen 7 3800X of the same specification.

Compressed file performance test▼

　　Compression software is often used by people. Because the compression software algorithms are different, the speed of compressing files among different compression softwares will be different. Here, two compression softwares are selected for testing: WinRAR, which is used by many people, and 7Zip, which comes with Benchmark.

▍　7-Zip benchmark score

　　In the 7-Zip test, the distance between AMD processor and Intel processor is very large. The score of Ryzen 7 3800X is 11.3% higher than that of i9-9900KF with the same core specification, and Ryzen 9 3900X continues to lead.

▍　WinRAR compressed file speed

　　WinRAR, the result here is reversed. Ryzen 9 3900X is 4.3% slower than i9-9900KF, and i5-9600KF is still stable at the bottom. Let’s click on the big picture to compare the other figures.

Performance test of office scenario simulation application▼

　　Most of the test items of PCMark are aimed at daily office applications, such as web browsing and document editing. Ryzen 9 3900X still doesn’t have much advantage, only 1.8% higher than i9-9900KF, which shows that CPU with high frequency and strong single core will be better used in this kind of project.

Professional software application performance test▼

　　Compared with the daily office work above, professional applications will test the performance of CPU more, among which multi-threaded applications are the majority. In theory, Ryzen 9 3900X with more cores will have more advantages.

▍　POV-Ray Benchmark

　　POV-Ray Benchmark is a software for testing the rendering performance of CPU. It can achieve results by rendering a large picture and calculating the average rendering pixels per second.

　　Ryzen 9 3900X outshines others, i9-9900KF is similar to AMD 3800X, while i5-9600KF, which has lost the number of threads, has fallen into the sewer and can’t get out.

▍　FHD X264 Benchmark

　　FHD X264 Benchmark tests and records the rendered frames by exporting the video. Ryzen 9 3900X here is not much different from i9-9900KF, only 6.4%.

▍　ArcTime Pro video compression and export

　　ArcTime Pro is the normal process of exporting video. Here, the performance of Ryzen 9 3900X with more cores is relatively normal, and the distance between i9-9900KF is a little bit.

　　This shows that if you do video work, it will be more popular with more cores/threads. Ryzen 9 3900X has the best performance in these products and is more suitable for video workers. The performance of i9-9900KF is also good. Although the number of cores suffers, the actual performance gap is not as big as the proportion of core numbers.

　　Summary of theoretical performance test:There’s nothing to say about small projects. The core specifications and performance of the processor are here. We can know what’s going on by comparing them. What Supercontinental wants to talk about here is the problem that AMD’s multi-thread performance surpasses Intel’s when its single-thread performance is slightly weak.

　　To put it simply, the SMT technology of Ryzen CPU is a little more powerful than the HT technology of Core I series, and the multi-core utilization rate is higher, which is why the single-thread performance of Ryzen 7 3800X is not as good as that of i9-9900KF in many of the above projects, but the multi-thread performance is reversed.

　　"Multi-frame" is bound to be the trend of future development.Win10 system is a good example. You won’t see the scene of Win7 "one core is in trouble, and N cores are watching" in Win10 system. AMD has made a better decision than Intel on how to optimize the performance of "multi-frame".

Game performance test

　　The number of game masterpieces this year is also dizzying, and the two processor manufacturers are also keen to use game performance as their selling point.

　　Here, six popular online games and 3A masterpieces are selected for testing, and the image quality is uniformly set to 1080P resolution, with the lowest image quality. The reason for this setting is to reduce the influence of graphics card bottleneck and maximize the performance difference of CPU.

▍　Tomb Raider: Shadow

▍　DOTA2

▍　GTA5

▍　Total War: Three Kingdoms

▍　Assassin’s Creed: Odyssey.

▍　Jedi survival: the great escape

　　Game test summary:All six CPUs can make the game run at more than 100 frames, but in Tomb Raider: Shadow, Total War: The Three Kingdoms and The Great Escape of the Jedi, the performance of Intel’s two high-end CPU games has obviously abandoned the rest of the processors.Take the position of the first brother of Intel Games..

　　The "extreme game performance" that Intel has been boasting is indeed well founded.However, the game running at such a high number of frames, except for some e-sports big brothers who use 240Hz screens, can actually ignore this frame gap to some extent.

　　Moreover, our test is based on the setting of 1080P resolution and the lowest image quality. If the image quality is properly raised, the graphics card and CPU will tend to be performance bottlenecks, then the gap between them will be narrowed.

Temperature and power consumption test

　　Because it is impossible to test the power consumption of a single hardware, there have been data errors when the software reads the hardware power consumption information. Here, Nortel instrument power consumption meter is used to test the power consumption of the whole platform, and Tomb Raider Benchmark is used to test the full load of the game.

　　I9-9900KF showed the phenomenon of frequency reduction during the test, and the power consumption was lower when the game was fully loaded and tested by Prime 95 than that of i7-9700K. Combined with the above Tomb Raider game test, the frame number of i9-9900KF in the game was not as good as that of i7-9700K, which can explain this phenomenon.

　　On AMD’s side, the power consumption of three generations of Ryzen processor can be effectively controlled by the 7nm process. The power consumption of Ryzen 9 3900X single baked FPU is only 278W, which is nearly 30W lower than that of i7-9700K, which has the highest power consumption. The former is a "miracle species" with four more cores than the latter.

　　As a result of opening PBO, three generations of Ryzen processor hit a temperature wall of 95°C together when baking FPU to reduce the frequency.

　　Intel processors have much lower power consumption and lower frequency at low frequency. The baked FPU of i5-9600KF with few cores is only 68°C, while the 8-core i7-9700K and i9-9900KF have reached the 90°C mark due to more cores and higher frequency, but the temperature is still lower than that of AMD processors.

Summary of PConline evaluation room

▼Comparison of comprehensive performance of six popular CPUs：

　　Hard to do the test, and finally for this comprehensive comparison table, which is the essence of the whole test.

　　The comprehensive performance gap table is the data obtained by synthesizing all the above test items except temperature and power consumption. Because many items will eat multithreading performance, Ryzen 9 3900X undoubtedly won the comprehensive performance championship.

　　Look at the other contestants, i9-9900KF and Ryzen 7 3800X with the same specifications. Although the latter is blessed by SMT technology, some multithreaded scenes will perform slightly better than the former.However, the game is the strong point of i9-9900KF, which lags far behind Ryzen 7 3800X, and wins by high-frequency performance..

　　Because i7-9700K has no hyper-threading function, even if the game is strong, the multi-threading scene drops too many points, and its comprehensive performance is even worse than that of Ryzen 7 3800X, and even it is almost caught up by Ryzen 5 3600X with fewer cores.

　　There is nothing to say about the i5-9600KF. Except for games, other projects are basically at the bottom, but U is actually a good U, but it just happens to be the cheapest and lowest specification one in this horizontal review.

　　Comparing Intel’s game strengths, there is no suspense, but in fact AMD is not too far behind Intel, which is worthy of surprise.

　　Because our game tests are all set to the lowest quality special effects to enlarge the game performance gap between CPUs, the gap will be even smaller if the high quality special effects are turned on.

　　Cost-effectiveness is also a concern for everyone to buy a processor, but there is no more scientific measurement method, so here is a simple and rude one.CPU price ÷ comprehensive performance percentage, get the unit price per percentage of performance. As a result of this calculation,Ruilong 3600X has the highest cost performance and i5-9600KF has the second highest cost performance..

　　Anyway, the smaller the number, the higher the cost performance.Overall, AMD Ruilong will be slightly more cost-effective than Intel Core..

　　As for the unscientific comparison method, I can tell you responsibly: it is good for everyone to have fun, and everyone has his own scale in his heart.

　　Because the higher the performance, the more difficult it is to improve the performance, so how to calculate here will be that the middle/low-end processors have higher cost performance: because the cost of realizing their performance is very low. High-end processors are expensive, and it takes hundreds or thousands of RMB to improve the performance of 10%. Whether it is worth it or not is a matter of opinion.

▼Summary time for expressing personal opinions — —

　　At the end of 2019, Supercontinental believes that it is meaningless to discuss the issue of "whether the processor performance is excessive".

　　As for the reasons, I don’t need to be embarrassed. Everyone is from the era of the media.The demand for creative CPU has soared., playing games to buy less core high-frequency CPU. For those creators and big UP owners, their demand for CPU performance can be said to be bottomless.

　　Therefore, regardless of the use requirements, all those who say that the CPU performance is excessive should be treated as hooligans.

　　Undeniably, in this year’s CPU market, Intel is still firmly on the throne of the game boss.I also changed my computer for playing games to i7-9700K.In some games with high demand for the stability of game frames, it is indeed better than AMD. (It’s not that I’m black, sometimes I really get stuck playing games with AMD processors.)

Sometimes I just get stuck suddenly and then I get disconnected.

　　On the comprehensive ability, AMD with "excess performance" will be even more brilliant.,In other words, AMD’s processors have become "all-powerful"Ryzen 9 3950X, which has the largest number of consumer platforms, has a higher acceleration frequency than any other Ryzen processor. What’s the concept? Not only do you have multi-core advantages at work, but you can also enjoy high-frequency advantages when playing games.

　　Coupled with the rest of AMD’s product lines, the "ceiling" EPYC Rome CPU with servers, and the weakness is the thread ripper of the fever platform. APU more suitable for the low-end platform will also come, and everyone can find their own heart water products in AMD.

　　This year is the flowering and fruiting period of AMD Ruilong.

　　It’s always good to have competition. AMD’s ZEN architecture has given people renewed confidence in Moore’s Law. In order to continue to consolidate its own market, Intel will also speed up the pace of new products, and ultimately, users will benefit. This year’s new CPU products are worthy of our happiness.

▼Guide for purchasing 6 processors (recommended) — —

▍　I5-9600KF 1399 yuan

　　Like i5-9400F, it is stillThis year, there is a high purchase value of CPU.In office, online games and most 3A masterpieces, it will have better performance, and the owner of Internet cafes should like this CPU better.

　　If the game you play is biased towards Tencent online games and the budget is not much, it will be a better choice.

▍　Ryzen 5 3600X 1499 yuan

　　Compared with the above two i5s, this processor has no price advantage.But the comprehensive performance will be stronger.. With the SMT hyper-threading function, I think it is more suitable for users who usually work and play games moderately, and they can also play games by editing pictures and repairing drawings. Professional performance is better than i5, and the game loses a little bit, but it’s not too bad.

▍　I7-9700K 2899 yuan

　　Subjective opinion:If you want me to recommend the CPU in 2019, I think this is the most fragrant CPU. After exceeding 5GHz, the game performance is off the charts, and it has experienced the latest wave of price reduction, which is very affordable.

　　Objective opinion:The 8-core specification is just right for most games, but it doesn’t have hyper-threading. It may not be as good as AMD’s Ryzen 7 series when dealing with work. It belongs to a processor made for games. After the price reduction, the price/performance ratio is really high. It is recommended for game enthusiasts with little budget.

▍　I9-9900kf3,499 yuan

　　The strongest game processor ordered by Intel, but there is also an i9-9900KS in this series, which is the complete body of the 9900K series.

　　Compared with i7-9700K, it has more hyper-threading function, and it has good performance in both games and work. Personally, it is suitable for game anchors — — Turn off Hyper-Threading when playing the game live, turn on Hyper-Threading when editing the essence live, and release the film quickly.

▍　Ryzen 7 3800X 2599 yuan

　　Ruilong 7Their positioning is equivalent to i9-9900K, but the game is obviously not as good as the latter.

　　Because they all have hyper-threading function, their comprehensive performance is stronger than Intel’s, and they are more suitable for working machines. It is recommended that users with low budget should buy them with good working performance and strong game performance.

▍　Ryzen 9 3900X 3999 yuan

　　4,000 yuan, I don’t think I’ll even know if I don’t have a mine at home.

　　The game is still inferior to Intel.But the comprehensive performance is the strongest here.,Those who pursue extreme productivity can consider it.,Or even more extreme, its eldest brother Ryzen 9 3950X.If you have a gold mine at home, you can also choose a higher-end thread ripper series.

　　　　　　　 CCTV News:The Central Committee of the Communist Party of China and the State Council recently issued the Outline of Healthy China 2030. What will happen to China’s health index by 2030? What impact will these changes have on public life? Let’s take a look.

　　　　　　　 1. prolong life and reduce death

　　　　　　　 In 2020, the average life expectancy will reach 77.3 years, and in 2030 it will reach 79 years.

　　　　　　　 The infant mortality rate, the mortality rate of children under 5 years old and the maternal mortality rate have respectively decreased from the current 8.1‰ 、10.7‰ And 20.1/100,000, down to 5.0&permil in 2030; 、6.0‰ And 12/100,000.

　　　　　　　 2. Eat nutritionally and exercise is guaranteed.

　　　　　　　 Formulate and implement the national nutrition plan, carry out evaluation and research on food nutrition function, and establish and improve the nutrition monitoring system for residents.

　　　　　　　 By 2030, the smoking rate of people over 15 years old will drop to 20%. The number of people who regularly participate in physical exercise has increased from 360 million in 2014 to 530 million.

　　　　　　　 By 2030, a three-level network of public sports facilities in counties and villages will be basically built, with a per capita sports area of not less than 2.3 square meters, and a 15-minute fitness circle will be fully covered in urban communities.

　　　　　　　 Ensure that students have no less than one hour of physical activity in school every day. By 2030, the standard rate of school sports facilities and equipment will reach 100%.

　　　　　　　 3. Health education has increased, and it is no longer fooled by health care "brick home"

　　　　　　　 Establish a core information release system for health knowledge and skills, and improve the monitoring system for health literacy and lifestyle covering the whole country. Incorporate health education into the national education system and take health education as an important part of quality education at all stages of education. In 2030, the health literacy level of residents will be raised to 30%.

　　　　　　　 Liu Yuanli, Dean of School of Public Health, Peking Union Medical College, China Academy of Medical Sciences:

　　　　　　　 At present, there is a gap between the average life expectancy and healthy life expectancy in China, and chronic diseases show a "blowout" trend. One in ten adults in China suffers from diabetes, one in four suffers from hypertension, and many people live with diseases and their quality of life is not high. If we only equate the pursuit of health with medical treatment and do not strengthen prevention, it will be difficult to cope with the severe health situation. Starting with healthy living, the planning outline helps people master scientific health knowledge and skills and develop good living habits, which is the most direct and proactive response to the disease challenge.

　　　　　　　 4. Increase in medical staff

　　　　　　　 By 2030, the health service capacity will be greatly improved, and a high-quality and efficient integrated medical and health service system will be fully established. The number of practicing (assistant) doctors per thousand permanent residents reached 3.0 and the number of registered nurses reached 4.7.

　　　　　　　 5. Improve the order of medical treatment

　　　　　　　 We will improve the medical and health service system, so that everyone in the province can enjoy homogeneous diagnosis and treatment of critical and difficult diseases and specialized medical services.

　　　　　　　 Establish a mature and perfect grading diagnosis and treatment system in an all-round way, and form a reasonable medical order of primary diagnosis, two-way referral, up-and-down linkage and rapid and slow division.

　　　　　　　 Li Bin, Director of the National Health Planning Commission:

　　　　　　　 China has established a medical security network covering 96.5% of the country through medical insurance for employees, new rural cooperative medical insurance and medical insurance for urban residents. On this basis, the medical security system has been gradually improved through serious illness insurance, commercial insurance and charity assistance, which has changed the situation of "minor illness, serious illness, etc." in the past. Although the coverage rate of medical insurance is over 95%, the overall level of medical insurance in China is still not high, and medical insurance should become an economical medical insurance.

　　　　　　　 6. Medical insurance is mature and stereotyped

　　　　　　　 By 2030, the universal health insurance system will be mature and stereotyped.

　　　　　　　 With the further development of modern commercial health insurance service industry, the proportion of commercial health insurance payment expenditure to total health expenditure has increased significantly.

　　　　　　　 Meng Qingyue, Dean of Peking University College of Public Health:

　　　　　　　 Without a sound medical and health service system, the role of medical and health investment and medical security system will be difficult to play, and it will be difficult for the people to benefit from health and healthy development. To improve the capacity of medical and health service system, we need to put people first, improve functions, strengthen cooperation and linkage, and promote the integration of medical and health service system.

　　　　　　　 7. The sky is bluer and the water is clearer

　　　　　　　 The ratio of days with good air quality in cities at prefecture level and above will exceed 80% in 2020 and will continue to improve by 2030.

　　　　　　　 The proportion of surface water quality reaching or better than Class III water bodies will exceed 70% in 2020 and will continue to improve by 2030.

　　　　　　　 By 2030, the food safety risk monitoring and food-borne disease reporting network will achieve full coverage.

　　　　　　　 8. Sewage discharge should be certified and agricultural production should be clean.

　　　　　　　 We will fully implement the management of industrial pollution source discharge permit, promote enterprises to carry out self-monitoring and information disclosure, establish a discharge ledger, and realize the discharge of pollutants with certificates.

　　　　　　　 Accelerate the elimination of processes, equipment and products with high pollution and high environmental risks.

　　　　　　　 Carry out special pollution control in industrial clusters.

　　　　　　　 Focus on steel, cement, petrochemical and other industries, and promote the transformation of industrial emission standards.

　　　　　　　 We will fully implement standardized and clean agricultural production, carry out in-depth risk assessment of agricultural products quality and safety, promote comprehensive management of agricultural and veterinary drug residues and heavy metal pollution, and implement action to control veterinary drugs and antibiotics.

　　　　　　　 Strengthen the guidance and supervision of food origin and improve the market access system for agricultural products.

　　　　　　　 Rao Keqin, Vice President and Secretary General of Chinese Medical Association:

　　　　　　　 At present, China is facing many contradictions and problems such as economic transformation and "multiple disease burdens", aging population and structural changes, ecological destruction and environmental pollution, and environmental sanitation needs to be improved, which requires us to change the mode of economic development and implement the strategic choice of interaction between green development and healthy environment. It is necessary to organically unify the construction of beautiful China and healthy China, mobilize the whole society to jointly create a healthy environment, and take human health as the center from urban planning, construction to management, so as to ensure the healthy life and work of residents and organically combine healthy people, healthy environment and healthy society.

On the afternoon of March 5th, when General Secretary of the Supreme Leader attended the deliberation of his Jiangsu delegation at the Second Session of the 14th National People’s Congress, he proudly recounted the achievements of China’s transportation development: "Now China’s automobile production and sales volume is the largest in the world, new energy vehicles are the best, and the highway mileage is also the longest. High-speed rail has gone out, urban rail transit has also gone out, ships have also gone out, and we have also built large aircraft, which is the ‘ Three pearls ’ It’s all made … …”

Traffic is the pioneer of China’s modernization. The general secretary once compared the traffic map of the whole country to a painting, demanding that "the traffic of beautiful China be outlined more beautifully".

Under the earnest entrustment of the General Secretary, the beautiful prospect of China’s transportation power is gradually becoming a reality. Today, let’s follow "AI Pictorial" and enjoy the magnificent picture of "opening the road on every mountain and bridging the bridge when encountering water", which is full of hope, vitality and dreams.

This is the C919 plane shot on the tarmac of Shanghai Hongqiao International Airport on May 28th, 2023. On the same day, flight MU9191 of Eastern Airlines, which was carried by C919 large passenger plane, landed smoothly at Beijing Capital International Airport, marking the successful completion of the first commercial flight of this aircraft and its official entry into the civil aviation market.

Traffic is the "artery" of economic development, and the cause of traffic always has a heavy weight in the heart of the supreme leader General Secretary.

In Xiangxi, Hunan Province, the General Secretary specially visited Aizhai Extra-large Suspension Bridge and asked carefully how the bridge was operating and whether the lives of local people had improved.

At the Tianjin Port Terminal, the General Secretary is very concerned about how to make the port bigger and stronger, pointing out that "the economy needs to develop, the country needs to be strong, and transportation, especially shipping, needs to be strengthened first";

At Beijing Daxing International Airport, the General Secretary carefully examined the process of intelligent technology and full self-help paperless intelligent check-in, and pointed out that Daxing International Airport should be built into a "world-class aviation hub" to show the wisdom and strength of the people of China to the world;

… … … …

A bridge spans north and south, all the way to all directions. Floating China, generate has developed vigorously in the construction of a powerful transportation country.

Up to now, the total mileage of China’s comprehensive transportation network has exceeded 6 million kilometers. From Linhai Xueyuan to Jiangnan water town, from Saibei Gobi to Lingnan mountains and rivers, 159,000 kilometers of railway networks crisscross, and 45,000 kilometers of high-speed rail lines are interwoven into a network. In 2023, China completed 61.25 billion person-times of cross-regional personnel mobility, up 30.9% year-on-year. The "travel radius" of Chinese is getting longer and longer, and the good life is constantly extending.

Behind the remarkable achievements, it is inseparable from the support of science and technology. When attending the deliberation of the Jiangsu delegation, the general secretary pointed out that it is necessary to "take scientific and technological innovation as the guide, make overall plans to promote the upgrading of traditional industries, the growth of emerging industries, the cultivation of future industries, and strengthen the deep integration of scientific and technological innovation and industrial innovation."

In recent years, China’s transportation science and technology innovation has achieved a historic breakthrough from quantitative accumulation to qualitative leap, from local advanced to system capacity improvement.

In Fuxing series EMUs, China has completely independent intellectual property rights for all key system software, and the China standard used accounts for 84%; During the construction of Daxing Airport Station, the builders installed 1232 shock-absorbing pads under the terminal building of Daxing Airport to minimize the vibration caused by trains passing through underground tunnels at high speed. Intelligent high-speed rail, intelligent highway, intelligent port, intelligent shipping, and intelligent postal service have accelerated to take shape, criss-crossing China … … Transportation has a stronger "science and technology flavor" and the level of modernization has been greatly improved.

When the road is clear, everything will flourish. The road network is criss-crossed, the routes reach the whole world, and the ocean-going ships shuttle back and forth, which drives the integration and development of industry, tourism and culture, and effectively unblocks the domestic and international double cycle. China high-speed rail, China Road, China Bridge and China Port, which are going global, intersect with the world and communicate with the times, and promote China’s deeper integration into the global industrial chain supply chain system.

In January 2023, the most "frost-resistant" and intelligent member of Fuxing family — — Fuxing alpine intelligent EMU is speeding on the land of Northeast China.

"The transportation industry is moving forward step by step, ahead of the world, and craftsmen are very important in it. It is not enough to design the light drawings well, and finally it will be implemented in the hands of welders. ‘ Without Jin Gangzuan, we can’t do porcelain work ’ 。” When participating in the deliberation of the Jiangsu delegation, the general secretary was concerned with transportation talents.

As a "craftsman" from the front line, representative Sun Jingnan shared her thoughts at the meeting: "What is ‘ Craftsman ’ ? Is to treat yourself in the professional field ‘ Haggle over every ounce ’ After tempering, breakthroughs can be achieved. "

With the rapid development of transportation industry, the demand for high-quality talents is also more vigorous. In recent years, Sun Jingnan has never kept secrets with his apprentices, and led the team to complete one technical research and achievement transformation after another. In the future, Sun Jingnan plans to work with more skilled craftsmen to manufacture high-end, intelligent and green rail transit vehicle products with exquisite skills and welding guns in his hands.

If you do not stop, the future can be expected. Nowadays, a mobile China is marching steadily towards the vision of "people like their actions and things are superior to their flow". The dense modern three-dimensional transportation network has made people’s "happiness road" smoother and smoother, and also provided solid support for Chinese modernization.

　　The financial crisis gave Medvedev a chance to challenge Putin. In the past few weeks, Medvedev has completed the path of democratization that Russia has not taken in the past years. His new act is obviously at odds with Putin, who is famous for his iron fist style.

　　Text/Gong Quan

　　The first anniversary of Medvedev’s presidency of Russia, Russians have already suspected that the Mapp group is moving towards division. This suspicion came from the western world earlier, because there is almost no long-lasting "double-headed politics" in Russian political history.

　　In the past two months, Medvedev criticized Putin’s government twice in public for being too slow and inefficient in the economic crisis. These statements not only exposed the real economic situation in Russia to the world, but also pushed himself to the political front of Russia.

　　The prosperity of Putin’s era is over.

　　In the past nine years, Putin has been a hero of Russia and his authority is unshakable. Yeltsin also had such a golden age, although it was relatively short. The crisis in 1998 brought the status and prestige of then Russian President Yeltsin to the lowest point. Today’s financial crisis has led to demonstrations in many cities in Russia. The opposition pointed its finger at Putin, saying that Putin failed to cope with the crisis and asked him to take the blame and resign.

　　Deriagin, a Russian economist, believes that "the economic prosperity in Putin’s era has ended, and part of the reason for this situation is the financial crisis, but it is mainly because the Russian government has not adjusted its economic structure and reduced its dependence on oil in recent years".

　　The "oil economy" is the straw for Russians to get rid of the economic crisis in the 1990s, and it is also the magic weapon for prosperity in the Putin era. It made "Putinism" warmly welcomed, and it gradually evolved into a symbol of restoring the glory of the empire. Its singleness is suitable for Putin’s economic principle of "controllable management" and political principle of "democratic sovereignty", but it does not conform to the diversified economic development principle in the era of globalization.

　　During Putin’s eight years in power, oil export has provided capital for Russian economic development, and it has gradually become a locomotive for Russian economic development. However, over-reliance on the export of energy products to promote economic development has also laid a hidden danger for the Russian economy, which makes the Russian economy vulnerable to international economic fluctuations.

　　According to the data of Russian Ministry of Finance, from 2000 to 2007, Russia gained a total of 475.7 billion US dollars in foreign exchange reserves by rising oil prices, of which 72% was used for state finance and the rest was used for government current account expenditure.

　　However, due to the impact of the Wall Street financial crisis in the United States, the price of international futures crude oil fell rapidly, and the Russian capital market fluctuated violently. In November 2008 alone, Russia’s foreign exchange reserves shrank by 28.87 billion US dollars, and the ruble also depreciated rapidly.

　　At present, among the three major international credit rating agencies, except Moody’s, Russia’s foreign exchange market has a positive rating, and the other two S&P and Fitch have given negative ratings.

　　"Because the financial crisis is highly contagious to the global capital market and the real economy, it is difficult for Russia to be immune from the economic crisis, while the Russian economy is dominated by a single energy export, and it may face a more serious impact than other countries." Professor Wang Ning, an expert on Russian issues at Shanghai International Studies University, commented on China Newsweek.

　　At present, the price of Russian Urals crude oil is the main basis for the Russian government to make economic policies, but it also makes Russian economic policies contain many uncertainties. In 2009, the Russian government’s budget was calculated at an average price of $95 per barrel, and in 2011 it was $88.

　　However, on March 13th, new york international crude oil futures traded at $46.25 per barrel. This also gives people reason to worry that if this situation continues, the Russian government deficit will continue to expand. The economic stimulus plan formulated by the government cannot be unaffected.

　　Earlier, the British "Guardian" published a heavy news that Putin was considering stepping down. There are rumors that Putin is considering resigning as prime minister in order not to make himself the focus of public dissatisfaction.

　　Medvedev’s road to democratization

　　Since Medvedev was elected president of Russia, it has been predicted that he will only be in office for about 18 months, and then he will step down, paving the way for the current Prime Minister Putin to return to the presidency.

　　One of the most noticeable decisions after Medvedev took office was to go to war with Georgia. However, during the war between Russia and Georgia, people saw more Putin than Medvedev on TV.

　　But the financial crisis gave Medvedev a chance to challenge Putin.

　　"Our actions are too slow, which is unacceptable in times of crisis. The problem is not the disintegration of macroeconomics or global finance, but the action is not fast enough and the efficiency is not high. " On February 20, 2009, Medvedev publicly criticized the government’s performance in the economic crisis at a meeting in Irkutsk, the eastern Siberian city. Medvedev asked the Russian government to improve administrative efficiency and convey the economic plan to the Russian people more clearly and concretely.

　　According to the statistics of the Russian Federal Statistical Office, the industrial production value of Russia fell by 16% in January, reaching a record high. The CPI is still as high as 13.9%.

　　While expressing his dissatisfaction with the government, Medvedev also started a series of actions of "changing blood" by the government.

　　Due to dissatisfaction with the local government’s actions in the economic crisis, Medvedev removed the posts of governors of four Russian states, all of which were nominated by Putin, and the newly appointed governors also included non-ruling party members. Medvedev hoped to restructure the local economy through the method of "changing blood".

　　Local government affairs are an important symbol of Putin as a "real prime minister". Russia’s political tradition is that the local chief executive is appointed and removed by the president, and local affairs are handled by the president’s office. However, Putin signed a decree on the eve of leaving office as president, stipulating that the annual report of the local chief executive should be submitted to the government first, and the prime minister should make an evaluation result before submitting it to the president.

　　Regarding this personnel change, Medvedev made an "early warning" before. He once pointed out in a televised speech that the Kremlin will not turn a blind eye to officials who are "incompetent, lazy and dereliction of duty".

　　According to the ITAR-TASS news agency, on March 13th, Russian President Dmitry Medvedev appointed young Ye Linna Cisco Linnik as the new Minister of Agriculture to replace Gordeyev. Prior to this, Gordeyev had served as Minister of Agriculture for nearly 10 years.

　　Ye Linna Cisco Linnik is a CEO with a double degree in medicine and business management, a typical elite outside the political circle. According to Russian media reports, Medvedev’s new candidate has been well received by Russian industrialists. Ye Linna Cisco Linnik will therefore become the first female agriculture minister of the Russian government.

　　In the past few weeks, Medvedev has completed the path of democratization that Russia has not taken in the past years.

　　He vetoed the Duma’s proposal to expand treason; Resume the operation of the Russian Human Rights Council and appoint new candidates; It is required to improve prison conditions and encourage prisoners to use electronic handcuffs (which look like bracelets and can determine the location of prisoners) instead of custody; Lower the threshold of the Duma, give more power to smaller political parties, meet with independent media representatives and appoint opposition figures.

　　On March 10th, Medvedev presided over the working meeting of the Russian Anti-Corruption Commission for the first time, and made the fight against corruption the focus of his work. On the same day, he also signed a five-year draft administrative reform of the Russian government, aiming at improving the administrative efficiency of the government.

　　For Russians with liberal ideas, they think that with the passage of time, the president who has never served in military service is opening up his own new political path and taking a more liberal route than his predecessor.

　　They haven’t split yet.

　　However, under the current economic situation, Russia needs Mapo’s cooperation more than ever to stabilize economic and social development. The reality also shows that "Mapp combination" continues to play a role.

　　"There may be cracks in the political relationship between Mapp, but it hasn’t split yet. Because there is no obvious conflict between Mapp under the current conditions. " Robert Cutler, a Russian expert at Carreton University, told China Newsweek.

　　Timakov Wa is Medvedev’s press spokesman. Whenever the media asks her about the differences between Medvedev and Putin, she always gives the same answer, and her answer is the same as what Putin said at first: the working relationship between the president and the prime minister is just as stipulated in the Constitution, and their rights and responsibilities are clearly defined.

　　At present, there is no report about Putin’s "counterattack" against Mei. After Medvedev expressed dissatisfaction with the Russian government’s economic actions, the Russian government actively took measures, on the one hand, to introduce the measures currently implemented in Russia more clearly, on the other hand, to increase the implementation of economic policies.

　　On March 11th, after introducing a series of economic measures taken by the Russian government to the coal miners of state-owned coal mining companies, Putin said at the meeting between the government and the regional development committee that the Russian government’s economic assistance to the region would rise to 300 billion rubles (about 8.57 billion US dollars). He asked local governments to conscientiously perform their duties and make good use of every penny to prevent repeating previous mistakes.

　　Russians are increasingly unable to judge who is in charge of decision-making. According to a survey conducted in March this year, 12% of Russians believe that Medvedev has the final say, and another 34% believe that Putin still plays a major role in Russian affairs. In addition, half of people think that Putin and Medvedev are equally divided in power sharing. ★

　　In recent trading days, the Shanghai Composite Index fluctuated repeatedly below 2900 points, and the market trading activity dropped significantly. The single-day turnover of the two cities in the past two days was less than 500 billion yuan.

　　China securities journal’s article said that in retrospect, the A-share bull market has always gone up and down sharply, and on the way up, there will always be one or two "diving" under the joint action of internal and external factors. At present, the market has limited room to fall, and the rebound momentum is gestating.

　　Some analysts believe that the trend logic behind the stock market operation has not changed since the beginning of the year, and the main contradiction in the market operation will shift from interest rate downward policy friendliness to economic recovery and fundamental inflection point.

　　According to data released by the National Bureau of Statistics on the 9th, the consumer price index (CPI) rose by 2.5% year-on-year in April, hitting a six-month high and rising by 0.1% quarter-on-quarter.

　　In the view of some research institutions, the decline in new credit in April was mainly due to seasonal factors, and the credit expansion rate was generally stable. The tone of prudent monetary policy has not changed. It is still the key to steady economic growth to dredge the transmission mechanism of monetary policy and keep the "quantity" moderate and "price" reasonable in the future.

　　Li Jing, vice chairman of JPMorgan Chase Asia-Pacific region, also said recently that she is optimistic about the performance of China stock market. Loose fiscal and monetary policies and moderate economic recovery; Market valuation is more attractive at the beginning of this year; RMB exchange rate is stable; The Fed’s policy stance is more moderate; China’s support for capital market financing policy and other five factors will bring benefits to the stock market.

In the market, it launched an electric car with its sub-brand Deep Blue, which symbolically broke the conventional limit of battery life and reached a striking 700 kilometers.

The achievement of this mileage not only reflects its profound technological accumulation in the field, but also reflects its far-reaching consideration for future travel methods. The advent of Deep Blue SL03 is undoubtedly a great news for consumers who have long been concerned about the development and innovation of new energy.

It not only meets the needs of long-distance driving with its excellent battery life, but also stands out in the highly competitive market with its unique design and technical configuration. Changan Automobile’s move obviously sets the tone for the future trend of the automotive industry, that is, the integration of battery life, design and technology is the key to the development of new energy vehicles in the future.

The exterior design of the Deep Blue SL03 is a direct response to the aesthetic trend of contemporary young consumers. The sleek body lines, coupled with a slip-back roof, not only greatly enhance the vehicle’s dynamic aesthetics, but also virtually reduce air resistance, helping to achieve a longer range. The hidden door handles further highlight the futuristic feel and integrity of the vehicle, while the dive-style front design combined with the sharp headlights shape shows its extraordinary sporty genes.

These design details are not only the pursuit of modern design trends, but also the perfect combination of power performance and aesthetics. Changan Automobile proved to the market through the dark blue SL03 that technology and fashion can be perfectly integrated in the design of electric vehicles, providing consumers with a driving experience that is both environmentally friendly and extremely aesthetic.

Turning to the interior of the Deep Blue SL03, the interior of this sedan is equally striking, successfully combining a sense of luxury with a sense of technology to provide drivers and passengers with a comfortable experience that exceeds expectations. Soft-touch materials and high-grade leather are used extensively in the interior to create a warm and refined environment. The seat design not only emphasizes the principle, providing excellent support and comfort, but also reflects the fine polishing of details by Deep Blue.

The design concept of the central console is simple and clear, but it does not lose the technological style. It is equipped with a large-size touch screen and a digital LCD instrument panel, which significantly enhance the intelligence level of the vehicle. In addition, the addition of ambient lights and the configuration of the panoramic canopy undoubtedly enhance the emotional experience during driving, allowing people to enjoy a quiet and comfortable journey even at night.

The performance of the Deep Blue SL03 in terms of power performance is also commendable. The car is expected to be equipped with two different power output motors, each of which can peak at 225Nm, ensuring that the vehicle can be quickly accelerated whether in urban congestion or on open highways. The layout not only guarantees the stability of the acceleration process, but also allows the acceleration time of 100 kilometers to be only 4.9 seconds, demonstrating the outstanding performance of the Deep Blue SL03.

More importantly, the Deep Blue SL03 is also equipped with advanced intelligent driver assistance systems and a new generation of arrays, which not only greatly improve driving safety, but also make driving easier and more enjoyable. The intelligence system can monitor the environment around the vehicle in real time, and provide the driver with the most suitable driving suggestions through accurate data analytics to ensure that every trip is safe and worry-free.

The deep blue SL03’s battery life is impressive, providing two battery options, capable of achieving a range of 515 kilometers and 705 kilometers respectively, and the performance of its extended range version is even more amazing, with a comprehensive range of 1,200 kilometers. This battery life performance not only means that there is almost no need to worry about power problems in daily use in cities, but also can easily handle even long-distance travel, greatly broadening the use of electric vehicles and client base.

The deep blue SL03 proves to the market that new energy vehicles can fully meet the travel needs of modern people, whether it is short-distance or long-distance, it can provide stable and reliable power support.

In terms of intelligent experience, the Deep Blue SL03 has spared no effort to demonstrate the strength of its future technology. The intelligent driver assistance system on the vehicle integrates advanced algorithms and 34 sensors, including 4D millimeter wave radar and ultrasonic radar, which can fully perceive the surrounding environment of the vehicle and monitor possible safety hazards in real time, thus providing more accurate driving assistance and safety warnings.

The addition of these intelligence systems not only significantly improves driving safety, but also greatly reduces the driver’s driving burden, making the driving experience more relaxed and pleasant. In addition, the intelligence of Deep Blue SL03 is also reflected in its interaction with users, providing drivers with a more personalized and convenient driving and life experience through intelligent voice assistants and vehicle to everything services.

When it comes to safety, the Deep Blue SL03 is equipped with a number of advanced safety features, including lane departure warning, forward collision warning, and active braking. These systems can automatically intervene at critical moments to prevent potential accidents and provide comprehensive protection for occupants.

It also brings great convenience to long-distance driving, ensuring that the vehicle can travel stably on the roadway and reduce driving fatigue. These safety features of the dark blue SL03 not only reflect the manufacturer’s emphasis on occupant safety, but also represent the continuous progress and innovation of modern safety technology.

Although the increase in sales is not small, Wei Xiaoli’s profit is more and more lost, and even further expanded.

Recently, NIO, Xiaopeng and ideal 2022 financial reports have been released. Data show that in 2022, NIO’s total annual revenue reached 49.27 billion yuan, an increase of 36.3% year-on-year; the annual net loss reached 14.437 billion yuan, an increase of 259% year-on-year; Xiaopeng’s total revenue was 26.86 billion yuan, an increase of 27.9% year-on-year; net loss reached 9.14 billion yuan, an increase of 88.1% year-on-year; ideal annual revenue 45.29 billion yuan, an increase of 67.7% year-on-year; net loss 2.03 billion yuan, an increase of 534.4% year-on-year.

In 2022, "Wei Xiaoli" delivered 122,500, 120,800 and 133,200 vehicles respectively, an increase of 34%, 23% and 47.2% year-on-year respectively. While the scale is expanding, the loss is also expanding, and the phenomenon of "the more you sell, the more you lose" still exists.

In this calculation, last year NIO sold a loss of 118,900 yuan, Xiaopeng sold a loss of 75,700 yuan, ideal to sell a car will lose 15,200 yuan.

Huatai Securities released a research report saying that "affected by the price cuts of Tesla and BBA, Wei Xiaoli’s short-term sales volume and gross profit margin may be further pressured."

continuous losses

Previously, Li Xiang had publicly stated that he would achieve a monthly income of over 10 billion yuan in 2022, and would also bid farewell to seven consecutive years of losses. However, according to the current trend, the ideal turning point is to increase losses rather than decrease them.

2022 is a big year for Li Auto’s products. Higher-end products mean higher added value and higher profit margins, but in fact, the ideal L9 has not achieved the desired effect in driving up gross profit margins.

Data show that Li Auto’s gross profit margin in the fourth quarter of last year was 20.2%, and the annual gross profit margin was 19.4%, compared with 21.3% in the previous year. In this regard, the official said that the reason for this phenomenon was due to the loss of Ideal ONE inventory provisions and purchase commitments last year.

What the official said was the ideal consumer rights controversy that occurred in the middle of last year, specifically because Ideal stopped production of Ideal ONE in order to pave the way for the upcoming L series new car, but they slashed the price of the car in order to clear the inventory, which made those Ideal ONE owners who bought cars before feel aggrieved, because the official sales had made them a similar promise of "no price reduction, no production suspension".

Finally, Ideal has to promise owners that it will add another three years (20G/month) of free traffic on the basis of the original data service, and extend the supply guarantee period of the original parts to 12 years to ensure that Ideal ONE owners are not affected by the discontinuation of the model.

However, the ideal vehicle gross margin of 19.1% is still high compared to NIO and XPeng Motors.

Li Auto is 44.11 billion yuan in the same period, the gross profit margin of cars is 19.1%, and the average price of bicycles is 331,000 yuan; NIO’s car sales revenue in 2022 is 45.5066 billion yuan, the gross profit margin of cars is 13.7%, and the average price of bicycles is 373,000 yuan; XPeng Motors is 24.84 billion yuan, the gross profit margin of cars is 9.4%, and the average price of bicycles is 206,000 yuan.

There are two core reasons for the increase in the scale of NIO’s losses. One is that the quality of profits has dropped sharply, and the other is that too much money has been spent. From making cars to changing electricity, to making mobile phones, batteries, and chips, NIO has almost laid out the entire car manufacturing industry chain, directly driving NIO’s R & D investment in 2022 to increase by 136% year-on-year, reaching 10.836 billion yuan.

The core reason for the poor performance of financial data is that Xiaopeng’s cars are sold less. For the whole year of 2022, XPeng Motors delivered 120,757 vehicles, an increase of 23.0% over 2021, only about 50% of the target was completed, and it was also overtaken by NIO’s 122,486 vehicles and the ideal 133,246 vehicles.

Challenges remain

In order to improve the current situation, XPeng Motors made significant adjustments to its internal organizational structure on November 30, 2022, establishing five virtual committees to open up communication channels across the company’s business lines to improve collaboration efficiency. At the same time, XPeng Motors co-founder Xia Heng resigned as an executive director of the company’s board of directors. *******cheng, the former vice president of XPeng Motors, chose to leave after being appointed as XPeng Motors CEO assistant, and Wang Fengying, the former general manager of Great Wall Motors, joined XPeng Motors as president.

Judging from the actions of XPeng Motors in recent months, it is undeniable that He Xiaopeng is indeed making a drastic reform. But so far, the change has not been significantly effective. Under He Xiaopeng’s plan, the company’s sales are expected to increase significantly from the third quarter of 2023.

On March 10, XPeng Motors launched the mid-term model of Xiaopeng P7 – the new P7i, but unlike the current car companies have reduced the price, the starting price of the new P7i 249,900 yuan is not only compared with Xiaopeng P7 without any decrease, but also increased by 40,000 yuan. In the eyes of industry insiders, such pricing may make XPeng Motors’ recovery more difficult.

In terms of NIO, after years of high R & D, heavy service, and high investment, NIO has gradually gained a place in the high-end market, but the problems facing it are still severe. After experiencing high growth, the scale growth rate has gradually declined, even lower than that of many new power automakers.

"According to the retail data of the China Automotive Center, NIO ranks first in China’s high-end electric vehicle market with a transaction price of more than 300,000, with a market share of 54.8%. In the high-end electric vehicle market with a transaction price of more than 400,000, the market share reaches 75.8%." Li Bin stressed at the performance conference that it is obvious that this is the most important trump card for NIO at present.

According to incomplete statistics, NIO has accumulated losses of over 90 billion yuan since its establishment, including a loss of over 4 billion yuan in just one quarter last year.

In order to get more sales, NIO launched NIO ET5 in December 2021 and began to grab the market downwards. However, perhaps for the reason of protecting the brand positioning, the minimum price of ET5 328,000 and did not fall below the 300,000 range, and although this car was placed high hopes by Li Bin, it cannot reach its target of 10,000 per month.

It is regarded as the first to achieve the ideal of profitability. In 2023, Li Auto’s sales target is 250,000 – 300,000 vehicles. At the same time, the operating income will impact the scale of 100 billion.

In order to further lower the price, Ideal L7 and L8 launched a cheaper Air version. Ideal also focuses on two high-voltage pure electric vehicle platforms this year, Whale and Shark, which can solve the problem of slow charging and achieve the same cost as the extended-range model.

"In less than a year, Li Auto has achieved full coverage of the $300,000 to $500,000 family SUV market. In 2023, Li Auto will challenge the 20% market share of the entire luxury SUV market in the $300,000 to $500,000 price range," Li Xiang emphasized in a conference call after the fourth quarter and full year 2022 earnings.

But it cannot be ignored that the entire automobile end point market is currently involved in a "price war", and multi-party extrusion will erode the living space of more new forces. Although Wei Xiaoli is full of confidence, the cruelty of the market may add further variables to this year’s planning.

　　Xinhua News Agency, Beijing, June 21st　

　　Xinhua News Agency "Xinhua Viewpoint" reporters Li Shuangxi, Li Wei and Xie Ying

　　Recently, it is the peak period for college students to submit course papers, defend and review their graduation thesis. A survey by Xinhua Viewpoint reporter found that some college students are quietly using AI (artificial intelligence) writing software such as ChatGPT to write papers, or using AI to assist paper writing, such as listing outlines, polishing language and reducing repetition rate.

　　Will AI writing software encourage academic fraud? Should I care?

　　AI software to write papers

　　Cheng Guangyu (pseudonym), a junior in a university in Beijing, will hand in four course papers this semester, each of which is required to be about 3,000 words. Cheng Guangyu didn’t spend time reading literature, sorting out, extracting and writing. He stayed up all night before handing in his homework and finished his paper with ChatGPT.

　　"At first, I was worried about whether I could finish it. As a result, I gave ChatGPT a general direction, and it listed the outline of the paper and automatically continued to write, which was much better than me." Cheng Guangyu finished four papers in one night, and submitted them to the teacher after simple revision.

　　According to the investigation in some colleges and universities, some college students use ChatGPT to complete course assignments, final papers and even undergraduate or master’s thesis. "The threshold for undergraduate graduation thesis is low, and I have no scientific research ability. Many people’s undergraduate papers are extracted and pieced together online, and it is more convenient to hand them over to artificial intelligence now. " Qiao Yifan (a pseudonym), a senior student at a university in Wuhan, said.

　　AI writing software can be used in all aspects of paper writing, from outlining and writing some contents to polishing language and reducing repetition rate. However, a college student who has used AI writing software in a university in Hunan Province thinks that the effect of modifying and polishing articles with AI software is not bad, but it is not appropriate to use it for substantive research and elaboration of innovative ideas.

　　The reporter found that AI writing software similar to ChatGPT is not uncommon in China. For example, Zhichuang helps AI, the secret tower writes cats, draws pictures and writes quickly, etc., and generally supports the writing of articles and papers. In addition, there are many articles teaching how to write papers with AI software on websites such as Zhihu and Xiaohongshu. In the experience sharing, some netizens said: "The teacher can’t see it at all", "Praise the AI ? ? paper for being well written" and "gave me excellent papers".

　　During the interview, some college teachers also found the characteristics of AI papers. When examining an undergraduate’s thesis, a teacher majoring in international politics in a university in Jilin Province found that his thesis on Japanese culture was biased, with blunt and lengthy language and empty content. Under the teacher’s questioning, the students admitted that the paper was written in ChatGPT.

　　In addition, some papers written with AI software are full of mistakes. "If you check it carefully, you will find that the links of the cited papers can’t be opened, the author’s name can’t be searched, the publication time, journals, pages, SCI divisions and other contents of the papers are all false, and even some historical events involved are out of thin air." He Shiming, an associate professor at the School of Computer and Communication Engineering of Changsha University of Science and Technology, said.

　　"Help scientific research" or "encourage cheating"?

　　Can ChatGPT be used to assist thesis writing? Many college teachers are controversial about this, including those who support users, those who resolutely oppose it and those who demand that it is strictly prohibited.

　　It is understood that some foreign universities have explicitly issued regulations prohibiting the use of ChatGPT to write papers. In China, academic journals such as Journal of Jinan (Philosophy and Social Sciences Edition) and Journal of Tianjin Normal University (Basic Education Edition) have successively issued explanations on the use of artificial intelligence writing tools, indicating that if the author uses relevant tools in his paper creation, he should explain the degree of use in detail in his article.

　　For research purposes, Yang Zhiping, a professor of Marxism at Northeast Normal University, tried to use AI writing software. He found that in order for AI to provide correct ideas, it is necessary to constantly "feed" the corpus to AI. In the questions and answers with AI, the original vague research ideas gradually became clear. "It’s like exchanging ideas with an expert with encyclopedic knowledge. Through the collision of ideas, new academic viewpoints can be inspired." Yang Zhiping said.

　　"AI writing software is just like search tools such as Google and Baidu. When it first appeared, it always caused people’s panic." Yao Yuchun, dean of the Institute of Social Sciences of Jilin University, said, but fundamentally, AI writing software is still a tool. It is a product of science and technology and needs to be treated dialectically. If students only use it for limited purposes, such as searching documents, listing outlines, sorting out ideas, etc., it is understandable and cannot be banned.

　　Fu Weidong, a professor at the Department of Artificial Intelligence Education of Huazhong Normal University, believes that both manual writing and AI writing should be regarded as academic misconduct as long as they exceed the prescribed repetition rate according to the existing academic paper norms. In addition, AI writing is based on the retrieval and processing of existing knowledge. Repetition of sentences or plagiarism of ideas is inevitable, which will inevitably involve disputes over intellectual property rights and portrait rights, and should be strictly regulated.

　　A college teacher in Hunan province is worried that if students are allowed to use AI to write, it will not be conducive to cultivating students’ scientific research ability. In the long run, it is easy for students to develop inertia and form a bad academic atmosphere.

　　In addition, the information security problems that may be caused by AI software have also attracted attention. Li Huilai, a professor at the School of Artificial Intelligence of Jilin University, said that some countries in Europe wanted to "block" ChatGPT because of data security problems, because there was a hidden danger of "collecting, using and disclosing personal information without consent" when it grabbed data. Li Huilai pointed out that when domestic students use ChatGPT, it may lead to the abuse of domestic scientific research results, and there are data security risks.

　　Actively respond to the academic challenges brought by AI technology

　　Some industry experts believe that, like search tools, as a technology, the popularization and application of AI is irresistible. The application standards of AI writing tools should be formulated as soon as possible to standardize the scope of use; At the same time, change the traditional evaluation mechanism of students in colleges and universities, and provide AI writing detection tools for researchers. In addition, it is necessary to strengthen independent research and development in the field of artificial intelligence and master core technologies.

　　Xiong Bingqi, president of 21st Century Education Research Institute, believes that it is difficult to ban AI writing software, and we should try to "keep the devil in a bottle" and make clear the scope and degree of use of AI writing tools. "It is better to face up to it than to avoid it. Colleges and universities can even offer public courses using AI writing tools, and clearly teach students the norms, methods and academic ethics. "

　　He Shiming believes that the duplicate checking software used in colleges and universities has been difficult to cope with AI writing. At present, universities and academic journals lack special software to detect AI writing, and it is inevitable to "hang a leak" only by human eye recognition. It is hoped that relevant domestic institutions will develop software to identify AI writing, and provide a safer and more reliable anti-academic fraud system for colleges and universities.

　　In order to avoid the influence of AI writing, some foreign universities are reducing the open homework after class, and putting more emphasis on classroom homework, handwritten papers, group work and oral test.

　　Xie Di, an associate professor at the School of Public Administration of Hubei University, suggested that the education department should pay more attention to students’ problem consciousness, observe, understand and analyze the society’s nature, and increase the proportion of content with substance such as experiments and investigations, rather than overemphasizing the form.

　　ChatGPT has powerful functions and may bring a new scientific and technological revolution. Li Huilai believes that domestic research and development of artificial intelligence should be strengthened. At present, some domestic companies are also developing similar products, but they are still in the initial stage and cannot form strong competition with ChatGPT.

　　"It is necessary to use the window period to accelerate the development of Chinese AI applications and AI paper detection systems, and strengthen the independent research and development of artificial intelligence core technologies." Fu Weidong said.
