Qiu Zhicheng: A Pre-publicized Suicide in Song Dynasty










Recently, the financial capital research platform, such as the Financial Research Institute, released a research report entitled "New Infrastructure, New Kinetic Energy, New Journey". The report pointed out that relevant enterprises have stood on the cusp of new infrastructure, and there will be incremental opportunities brought by the track upgrade, and there is huge room for imagination in the future.
For example, Guan Qingyou, president and chief economist of the Financial Research Institute, said that China’s development strategy has undergone a major change. Under the background of the establishment of a new development pattern with domestic big cycle as the main body and domestic and international double cycles promoting each other, the digital economy is the main focus of the double cycle, enabling industrial transformation and upgrading. New infrastructure is an important carrier of the digital economy, and the multiplier effect can be expected.
It is estimated that from 2020 to 2025, China’s new infrastructure can drive investment of 11 trillion yuan, with an average growth rate of 10%. A new generation of information technology and its application in line with the direction of industrial transformation and upgrading and high-quality development will be the main growth point of the future economy.
The report sorts out the participation of major enterprises in the seven industrial chains of new infrastructure, namely 5G, artificial intelligence, big data, industrial Internet, UHV, intercity high-speed rail and rail transit, involving about 500 enterprises. The report divides these enterprises into three categories. The first category is powerful comprehensive giants, represented by Huawei, Alibaba and Tencent. The second category is the old-fashioned strong players who upgraded the track, and the representative enterprises are Lenovo, BOE and Ziguang. The third category is the vertical cutting-edge enterprises that quickly rush to run, and the representative enterprises include Contemporary Amperex Technology Co., Limited, Iflytek, Huichuan Technology and Siweituxin.
What is the strength of the above 10 core representative enterprises? According to the report, among the 10 companies selected, except for unlisted Huawei, the market value of the other 9 listed companies reached 10.1 trillion yuan. If Huawei goes public and its market value is not less than 2.3 trillion yuan, the total market value of 10 companies will exceed 12.4 trillion yuan, equivalent to the total GDP of four urban areas in 2019, accounting for 12.5% of China’s GDP in 2019.
Although these enterprises are strong, they also show obvious differences. According to the report, with the rise of new infrastructure, integrated giant enterprises and vertically emerging enterprises are highly concerned and highly sought after in the secondary market, but the established strong ones are somewhat embarrassed. Generally speaking, the old and powerful players not only have traditional business as a solid moat, but also have incremental opportunities brought by the upgrade of the track. There is huge room for imagination in the future, but this has not been fully recognized by the market and needs to be re-examined and revalued.
Guan Qingyou believes that before this, the market regarded the old and powerful as processing and manufacturing companies or simple manufacturing companies and service companies. Today, they should be treated as digital economy companies or new infrastructure companies. The nature of the company has changed, and the valuation logic and valuation method of the capital market will also change accordingly.
In fact, behind the valuation changes is the deep transformation of enterprises. For example, Lenovo has transformed from a traditional hardware provider to a technology provider. In terms of 5G, we are deeply involved in 5G O-RAN, edge cloud and other fields. In terms of cloud computing and artificial intelligence, it provides super-large-scale data centers for public cloud customers and provides high-performance computing for the application of scientific computing and artificial intelligence. In terms of industrial internet, Lenovo has realized the complete autonomy and controllability of the software and hardware solutions of industrial internet.
Relevant industry experts said that infrastructure construction from highway to high-speed rail to informatization, corresponding economy from "world factory" to high-speed rail economy to digital economy, every time the infrastructure is upgraded, new formats, new models and new economies will be born. Established and powerful enterprises should seize the opportunity of the new infrastructure market, empower the intelligent transformation of the industry and realize their own transformation and development.
However, enterprises should also have a clear understanding of new infrastructure. Tong Fuyao, senior vice president of Lenovo Group and president of Enterprise Technology Group, said that we should also see that new infrastructure may bring more new challenges, such as data security problems brought by industrial Internet and edge computing, potential environmental protection problems in data center construction, and so on. This requires enterprises to better coordinate and cooperate, provide high-quality solutions for intelligent transformation, and jointly create a good new infrastructure market ecology.
In addition, Guan Qingyou also reminded that from the perspective of the capital market, new infrastructure is not a short-term concept or story, but has penetrated into all aspects of the national economy and is a long-term theme involving infrastructure upgrading. For enterprises, it is not necessary to scratch the concept, but to actively participate and become the main body of new infrastructure construction.
On March 28th, the police in Dongguan City, Guangdong Province reported that the online loan investment platform of Tuandai.com (hereinafter referred to as "Tuandai.com") was put on file for investigation on suspicion of illegally absorbing public deposits, which meant that another online loan platform was shut down due to violation of the law. The upstream journalist learned that as of February 28, the total loan balance of "Group Loan Network" had exceeded 14.5 billion yuan.
In addition, after the "Group Loan Network" was shut down, Tang Jun, another A-share listed company under the actual controller, also announced the suspension of trading. A person familiar with the matter said that the "group loan network" may have a financial deficit due to the break of the capital chain, and another main reason is that the "group loan network" failed to complete the filing due to violations.

▲ Notification from Dongguan Public Security Bureau.
The lender’s annual return rate of 970,000 is higher than that of similar platforms.
According to the industrial and commercial data of enterprise investigation, the main operator of "Tuandai.com" is Dongguan Tuandai.com Internet Technology Service Co., Ltd., which was established in 2011 and officially put into operation in 2012. It is a peer-to-peer lending information intermediary service platform dedicated to helping small and micro enterprises. As of May 2017, the derivative group of the parent company of "Group Loan Network" has completed a total financing of RMB 1.8 billion.
The upstream journalist saw in official website that as of February 28th, the total loan balance of the group loan network was more than 14.5 billion yuan, the interest balance was more than 1.3 billion yuan, the loan balance reached more than 390,000, the total number of borrowers was more than 970,000, and the number of registered people exceeded 8.36 million.

▲ According to the data of the group loan network, the current total loan balance has reached 14.5 billion yuan.
At the same time, the reporter noted that official website, a "group loan network", said that the highest annual return rate of automatic bidding could reach 11.5+3.5% in 36 months and 10+3% in December. The average annual return rate of similar platforms in 36 months is 8.4%; The average annual rate of return in 12 months is only 8.5%. Insiders of the online lending platform analyzed that the "group loan network" can reach a loan balance of 14.5 billion yuan in less than seven years, which is closely related to its high rate of return, but the high annual rate of return also has high financial risks. "This analysis, ‘ Group loan network ’ The closure has a lot to do with its financial pressure. " Insiders of the online lending platform said.
In addition, the reporter learned that on March 23, Tang Jun, the founder of the group loan network, mentioned at the meeting of offline big customers held by the group loan network in Dongguan that if it could not be put on record in the end, the group loan would buy back the bonds held by investors and use the company’s own funds as entrusted loans.
A number of investors revealed to reporters that the platform had experienced unstable income at the beginning of this year. The investment amount ranges from 1,000 yuan to millions of yuan. "I just took a fancy to the return of high interest rates. I have been investing for more than two years. I didn’t expect a sudden thunderstorm. Some of them have been withdrawn in advance, and some of them are still in the account. I don’t know if they can return after the expiration. " Investor Mr. Wang said.
According to a video provided by netizens, it is suspected that on the evening of March 27th, a large number of special police officers seized the headquarters of "Group Loan Network" in Dongguan Zhongchuang Financial Street, showing that five suspects were taken away by the police that day. On March 28, the reporter contacted the customer service staff of Zhongchuang Financial Street, and the other party said that the action on the evening of March 27 was a routine inspection of "714" anti-aircraft guns (referring to some high-interest online loans with a term of 7 days or 14 days, and "anti-aircraft guns" refers to their high "beheading interest" and overdue fees).

▲ The stock of the derivative group in which Tang Jun is the actual controller has been suspended.
The suspension of the affiliated company was alleged to be related to the "Little Yellow Dog" project.
According to the information of official website, Tang Jun, the founder of "Group Loan Network" mentioned in the police report, is also the chairman of Derived Technology Group Co., Ltd. (hereinafter referred to as "Derived Group") and "Little Yellow Dog".
On March 28th, shortly after the police announced Tang Jun’s surrender and compulsory measures were taken, the derivative group announced the suspension of trading and proposed that it would resume trading after disclosing the relevant announcement. On the same day, in the 2018 annual report released by the "Derivative Group", it was proposed that the net profit attributable to shareholders of listed companies in 2018 was 370 million yuan, which was 24% lower than that attributable to shareholders of listed companies in 2017.
The "Little Yellow Dog", which is also a subsidiary of Tang Jun, announced that the operating entity of Little Yellow Dog is Little Yellow Dog Environmental Protection Technology Co., Ltd., and the group loan network are two independent legal entities. There is no business connection between the environmental protection industry operated by Xiaohuanggou and the Internet finance industry operated by the group loan network. At present, Little Yellow Dog is operating normally.
The reporter learned that Xiaohuanggou Environmental Protection Technology Co., Ltd. was established in August 2017, specializing in new intelligent waste sorting and door-to-door recycling. Up to now, Little Yellow Dog has been laid out in 34 cities including Beijing, Shanghai, Guangzhou and Chongqing, and has installed relevant equipment in 6873 residential communities.
However, a person familiar with the matter suggested that the registration time of Xiao Huanggou was less than two years and the registered capital was 100 million yuan. According to the current layout, the actual income of Little Yellow Dog is not enough to support its large-scale expansion and operation. Therefore, it is possible that Tang Jun will invest the funds of "Group Loan Network" into the "Little Yellow Dog" project.

▲ The Xiaohuanggou project invested by Tang Jun’s subsidiary group said that everything is normal at present.
The police advised investors to report the case as soon as possible.
On March 28th, the reporter repeatedly contacted "Group Loan Network" through customer service phone, client, WeChat, Weibo and other platforms, but all indicated that it could not be connected or the customer service was not online.
The reporter noted that the police report not only mentioned that Tang Jun and Zhang Lin, the actual controllers of the "group loan network", were put on file for investigation and were taken compulsory measures for allegedly illegally absorbing public deposits, but also announced the registration method and expressed the hope that investors would actively cooperate with the public security organs to carry out investigation and evidence collection.
Dongguan police replied to the upstream journalist that all the registration channels have been opened at present, hoping that investors can reflect the situation and demands from reasonable and legal channels and register as soon as possible.
Recently, the news of the upcoming listing has intensified, and a large number of real car pictures of the new BMW X3 have been exposed on the Internet, indicating that the listing time is short. And this new car does not need to be introduced too much. It has just been upgraded in the past two years, and it is currently the latest large-screen design, which has made great progress in technology.
Then the problem comes, as a competitor of the same level of the new IPO time is long enough, the current price in the end point market is also a drop, many regional entry-level models have come to about 280,000, many small partners are guessing whether the new generation of Audi Q5L is coming.
Recently, the communication between Audi manufacturers and dealers has been exposed on the Internet. The key message is that the 25 Audi Q5L models are really coming. After careful study of this email, we found that there is not much information about the changes, which makes us a little disappointed. The new generation of Audi Q5L in the future will basically continue the design of the current model, so the good news is that there is no need to worry about the new car discount margin shrinking.

From this email, it is obvious that the design of the new Audi Q5L will not change, and the inner frame of the headlights will become black, that is, blackened. Although the appearance will not be adjusted, the black headlights are more sharp, and the appearance color of cloud gray is directly cancelled, while brown and red will be cancelled. At the same time, the new car retains black, white, blue, and Nado gray, further streamlining the configuration of the new car.

In addition, the storage box cover near the center armrest has also been added, which will effectively enhance the sense of privacy in the car. It is worth mentioning that the rear headrest pillow has also been added, but the rear seat angle that consumers are concerned about has not been adjusted. As we all know, the biggest shortcoming of the Audi Q5L is that the rear seat angle is straight, and it is easy to fatigue after a long ride, so many users call for the seat angle to be adjusted. In fact, this cannot be adjusted! The reason is very simple, because the change of sheet metal parts will be a systematic project, and domestic engineers do not have this authority.


So there won’t be much change to the 25 Audi Q5Ls. Let’s review the design of the current model again.
The manufacturer’s guide price of the current Audi Q5L is 39.88-48 8,800 yuan. At present, the entry-level model has fallen to about 280,000. At the price level, the new car has become more fragrant.
The exterior shape, the new car adopts a family style design, in addition to the sharp headlights, it also matches the black grille and black sports surround. This part of the configuration will not change much in the future, but the big lights will be blackened and stroked.
The rear of the model adopts a two-sided exhaust pipe design. In the body data part, the length, width and height of the Audi Q5L are 4770/1893/1667mm, and the wheelbase is 2709mm., Compared with the data of 25 models, there is no change.
The internal design has not been adjusted much either. The oversized panoramic sunroof and the 10.1-inch floating screen not only match these configurations for the current model, but also for the 25 models. More importantly, the current Audi Q5L lacks the intelligent driver assistance system in a large area, and the new model information exposure shows that a large number of fixed-speed cruise configurations will still be used in the future, so the intelligent system is still out of touch with the 25 Audi Q5L.
As for the power system, whether it is a new or old model, the whole series is equipped with a 2.0T engine, with a maximum power of 190 horsepower and 245 horsepower respectively. It is matched with a 7-speed wet dual-clutch gearbox. The whole series is equipped with four-wheel drive as standard, and it is still equipped with a front and rear five-bar independent suspension system.
In general, Audi manufacturers have to reduce the distribution of the new model, which is basically iron plate DingTalk. Not only is the configuration not too innovative, but the degree of intelligence is also not as good as that of competitors. So I think this is still a less sincere annual change. It is expected that the Audi Q5L will usher in a real big change in 2025. This year and the first half of next year will still rely on price.
1905 movie network news Since November 19th, the film has been highly anticipated by the audience. Both the production team that strives for perfection and the strong lineup led by the film have provided a strong quality guarantee for the film.
On November 2nd, the film released a special feature of "Little People and Great Heroes". Zhang Hanyu and Fan Wei, two powerful actors, vividly portrayed the brave and resourceful captain of the railway team and the undercover hero who was dormant with great concentration with superb acting skills. Two ordinary little people were responsible for fighting against the Japanese in their own ways, and wrote magnificent and poetic anti-Japanese war stories in troubled times. From the thrilling action scene of grabbing a train to the touching "deep affection between father and son", Railway Hero highlights the texture of a large film, but at the same time, it does not forget to incorporate ingenious ideas into its creation, striving to bring different screen experiences to the audience.
Zhang Hanyu performed the hard-core captain’s injury and insisted on filming "Pretender". Fan Wei’s wonderful crying moved the director.
During the War of Resistance against Japanese Aggression period, Lunan Railway Brigade, the 115th Division of the Eighth Route Army, hijacked trains and seized materials and weapons in Lunan, which was ravaged by Japanese invaders, creating many impressive records and dealt a heavy blow to the enemy. The film Railway Hero was based on the deeds of this team, reappearing the heroic spirit through brand-new stories and roles, and the "Lao Hong" and "Lao Wang" created by Zhang Hanyu and Fan Wei were the most representative figures. As the leader of the railway team, Lao Hong took the Jin-Pu railway line as the main battlefield with well-trained and orderly division of labor, and fought bravely with the Japanese invaders, "How to get on the train quickly" and "When to jump down", and the actors worked together to polish the interlocking details and wholeheartedly present the professionalism of the whole team.
Zhang Hanyu, who plays the hardcore captain, has many action scenes in the film. His back injury suddenly recurred for many years in one shooting, but he went into battle without changing his face and insisted on "shooting again", which was very professional. Lao Wang, the train dispatcher, "covered his face with wine", lurked around the Japanese aggressors through subtle camouflage to provide information for the railway team. A tortuous and different "father-son play" enriched the sense of hierarchy of the role.
Fan Wei devoted many wonderful crying scenes, whether it was "forbearing crying" to hide his identity or crying in the corner to vent his emotions, all of them showed solid skills, which made director Yang Feng and the staff on the side unable to help but shed tears.
Cosmetic clothing design is ingenious, and outlines the national justice of the little people with awe.
This film adheres to the awe of history and heroes in its creation. From the layout of large and small scenes to the characters, it has been thoroughly studied and devoted to the characteristics of the times. "The makeup of the time drama is more complicated and requires higher requirements." In fact, the heroes who defeated the enemy in the film were all ordinary people, and the creative team carefully studied and carefully designed each role. Lao Hong always has dirty fingernails, the rosacea formed by Lao Wang’s frequent drinking, the black-and-white beard that confirms his age, and the details make the characters more convincing.
In clothing, in order to present an old texture, the staff specially put stones and sand in the washing machine to wash with the clothes, and it takes several months to dye them into finished products. "In that special period, there were many people like Lao Wang", as Fan Wei said, every man is responsible for the rise and fall of the world, and Qian Qian’s "China nobody" ignored life and death and fought the Japanese aggressors to the end in exchange for a great victory in the war of resistance and defended the national justice.

【Under the guidance of Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era — — A new era and a new chapter.】
Source innovation to solve the technical problem of "stuck neck"
— — Enlightenment of an engineering teacher crossing the "four mountains" of achievement industrialization
Guangming Daily reporter Yuan Yufei
editorial comment/note
During his inspection tour in Fujian, the Supreme Leader General Secretary emphasized that our country must rely on innovation to enter the first phalanx of scientific and technological development, and it is not feasible to follow blindly. We must speed up the pace of self-reliance and self-improvement in science and technology. We should adhere to the core position of innovation in the overall situation of modernization, regard innovation as a national policy, and actively encourage and support innovation. Innovation doesn’t ask about "birth", but supports whoever can contribute to the country. There is such a teacher in Beijing University of Technology, who has innovated from the source of basic research, overcome the technical problem of "stuck neck" of industrial robots, and successfully industrialized the achievements of the thesis, providing a model for millions of researchers to make contributions in the new era.
"From basic research to industrialization of achievements, we must at least surmount the four mountains of theoretical verification, pilot test, capital investment and international market competition." Cao Jianguo, head of Tsinghua University Hebei Pilot Base, said, "For researchers, every mountain is full of difficulties, and success is rare."
But Zhang Yueming crossed these four mountains. His innovative industrial robot RV reducer technology from the source broke the Japanese monopoly, and with this technical cooperation, he set up factories in Yizhuang Development Zone in Beijing and Shijiazhuang in Hebei Province, and can produce 80,000 sets of RV reducers of the world’s top industrial robots every year, which is in short supply.
For a long time before, Zhang Yueming had been an unknown engineering teacher in the school. He graduated from Tsinghua University at the age of 32 and became the first batch of postdoctoral fellows in Beijing University of Technology. But at the age of 50, he was not a professor because his papers were not distributed as much as others.
Breaking the monopoly of foreign technology and helping domestic industrial robots go to the high end
The RV reducer of industrial robot is equivalent to the chip of mobile phone and computer for manufacturing industry, and its core technology and 90% of the global market have been monopolized by Japan. At present, a large number of RV reducers used by domestic robots are imported from Japan. In order to transform and upgrade China’s manufacturing industry, it is necessary to solve this technical problem of "sticking the neck".
When the reporter first met Zhang Yueming, it was in an industrial park in Beijing Yizhuang Economic and Technological Development Zone. The production machine in the workshop was still turning and the machine made a huge roar. On the same day, he took the reporter to visit the production plant with an investment of more than 200 million yuan.
"The production plant is my laboratory. These RV reducer samples are all produced according to the original technology independently developed by us. The production scale of Yizhuang Factory has achieved an annual output of 30,000 units. " It’s noisy, Zhang Yueming said loudly, pointing to a pile of shiny bearings on the display stage.
The test report that the reporter saw on the spot shows that these domestic RV reducer products are better than the most advanced products in Japan in terms of precision retention and service life.
"The reducer is the core functional component of industrial robots. For example, if the industrial robot is regarded as an adult’s arm, the reducer is equivalent to the joint of the arm, which mainly determines the swing accuracy of the industrial robot’s arm, and its wear and tear will affect the service life of the industrial robot after a long time of use. RV reducers are mostly used in the transmission of high-precision robots in the world. The legs, waist and elbows of an industrial robot need 4 to 6 RV reducers, which account for more than 30% of the total cost of industrial robots. " Zhang Yueming introduced.
"There is a gap between the quality of domestic RV reducers and Japanese products, mainly because the accuracy retention is not good; It is also easy to wear and tear, which affects the service life. Most of them are only used by middle and low-end industrial robots. What is even more helpless is that the price of reducers sold by Japanese companies to ABB, Fanuc and other four major robot companies is half or even lower than that of Chinese companies; Domestic manufacturers are forced to accept a long waiting period of 3 to 6 months to get the goods. " Zhang Yueming told reporters, "My main job now is to break the Japanese monopoly, help domestic industrial robots to go to the high-end market, and help China’s manufacturing industry transform and upgrade."
Breaking through the "bottleneck" technology of manufacturing industry requires basic theoretical innovation at the source.
In 1997, 32-year-old Zhang Yueming graduated from the Department of Precision Instruments and Mechanics in Tsinghua University, and entered Beijing University of Technology as a postdoctoral fellow, engaged in basic research of mechanical design and theory for a long time.
"It’s a shame to say that although I am the first postdoctoral fellow at Beijing University of Technology, my personal interest in scientific research has been in the production line, helping enterprises solve practical problems. Therefore, there are relatively few papers. " Zhang Yue said.
Zhang Yueming has published few papers, but his practical application results are not few. For example, Zhang Yueming cooperated with Beiyi Machine Tool to jointly develop the core functional components of CNC machine tools, which completely replaced those imported from Japan and has been applied to many models of CNC machining center products of Beiyi Dajing Machine Tool Factory, which also laid a good foundation for Zhang Yueming to be an RV reducer for industrial robots. He was inspired by this: "Many problems in China’s machinery manufacturing are not the problems of materials and technology, but the lack of original innovation."
"Mechanical products, like other high-tech products, contain rich scientific laws. Only by revealing their inherent motion laws and scientific principles can we produce high-quality products." Zhang Yueming told reporters.
Since the 18th National Congress of the Communist Party of China, the reform of China’s science and technology system has been further promoted, and the state has increased its support for basic research and "stuck neck" technology research, and Zhang Yueming has become a beneficiary. In 2015, Zhang Yueming won the scientific research project "RV Reducer Industrialization Development" of Beijing Science and Technology Commission, and got 2 million yuan of scientific research funds to develop the technology of "Robot Joint RV Reducer Manufacturing Process". He spent more than 1000 days and nights building a technical model of gear modification, solving the problem of gear wear, and finally mastering the core technology of "design and manufacturing technology of robot joint RV reducer".
"This technology is the real source innovation. There are many people who research and develop robot RV reducers in China, most of them are imitations, but the technology of Zhang Yueming’s team is forward design, innovative from the source, and some performance indicators are better than those of the Japanese. " Zhaojie, director of the Robotics Research Institute of Harbin Institute of Technology and head of the key expert group of intelligent robots in the national key R&D plan, told the reporter: "The Ministry of Science and Technology will be in ‘ Fourteenth Five-Year Plan ’ Support the industrialization of this technology during the period. "
"There are still many manufacturing industries in China ‘ Get stuck in the neck ’ Technology, many core components rely on imports, the solution of these problems, like RV reducer, needs to carry out basic theoretical innovation from the source. For example, 80% of bearings used in high-end mechanical products are imported. This has led to most domestic machine tool companies not making money, or even losing money continuously, and the money has been earned by foreign companies. " Zhang Yue said.
From basic research papers to industrialization of achievements, it is necessary to optimize the ecological environment for innovation and entrepreneurship.
Mechanism and Machine Theory (MMT) is the top international academic journal of the International Federation of Mechanism and Machine Science. It usually takes more than half a year for China researchers to publish papers in this SCI core journal, and Zhang Yueming’s papers will be published in one month. Peer review experts commented: "This is a rare good paper in recent years, which comes from practice. It is recommended that the published journal be published."
"University professors who engage in basic research generally don’t care about industrial transformation. After theoretical papers are published in international journals, they will be shelved. Many people even engage in research for projects and papers, but they are absent in the transformation of scientific research achievements that are more valuable to the country." Cao Jianguo said.
The first "mountain" that Zhang Yueming met was to verify the technical theory.
After the publication of this paper, industrial robot RV reducer has been highly recognized by peers at home and abroad in theory, but my heart is always put aside. For so many years, I have written fewer papers, and each one is also for service practice. My difficulty at that time was that the project of the science and technology commission was finished and there was no scientific research funding support. I need a machine tool to process samples to verify that the technology is correct, and then I can transform the industry. It takes tens of millions of yuan to buy a high-end processing machine tool. " Zhang Yue said, "This is a paradoxical problem: if I want to realize the industrialization of the results, I need to verify the theory first and have samples first, but enterprises usually have to see the samples before they invest money, so this result has been put on hold for a long time."
Later, by chance, Zhang Yueming saw the dawn of solving this difficult problem: an Italian high-end machine tool factory wanted to open up the market in China, and its director happened to know Zhang Yueming. Zhang Yueming talked with them about cooperation and asked the other party to help process the samples first, which just verified the performance of their machine tools, and the other party agreed.
Zhang Yueming and his team finally went to Italy to process the RV reducer samples of industrial robots, which verified that his theoretical results were completely correct. The samples sent to the national authoritative testing center are better than the most advanced products in Japan in terms of precision retention and service life.
With the sample, Zhang Yueming achieved a leap from basic theory to product, and then he met the second "mountain": the pilot project.
"Many researchers have reached this point and can’t go on. The pilot test is a long process, and some even take several years, so investors lack enthusiasm and motivation for the pilot test, which is the crux of the difficulty in transforming China’s original innovation achievements. " Cao Jianguo told reporters, "Judging from the transformation data of scientific and technological achievements in Tsinghua University for many years, only about 5 out of 100 scientific and technological achievements can form the final product." Cao Jianguo said.
People work hard, and God helps. In recent years, the changes in the global market environment have helped Zhang Yueming a lot. A manufacturer of reducers in Shijiazhuang took the initiative to seek cooperation.
"The reducer originally produced by our company has low technical content and fierce market competition, and it is urgent to transform and upgrade new technologies. We have done market research, and the domestic reducer is not doing well. The most fundamental reason is that there is no innovation in the basic theory of domestic reducer. Zhang Yueming has done a lot of work in combining theory with practice, and has made samples. " Hu Wenshi, the chairman of this enterprise, said in an interview, "Seeing his technology and samples, my eyes lit up. This is the core technology we are looking for, so we did not hesitate to spend 37 million yuan on technology and cooperation, and also spent 890 million yuan on foreign high-end machine tools and equipment to put into the pilot test, because once successful, our enterprise can realize the leap-forward upgrade from primary products to top products in the world, with broad market prospects."
On October 20th, 2017, Zhang Yue Ming signed a contract with enterprises in Shijiazhuang on behalf of the school, and jointly invested more than 200 million yuan to build a factory in Beijing Yizhuang Development Zone, and bought a machine tool for industrial production of domestic robot RV reducer.
The pilot project of Zhang Yueming’s team went smoothly, but soon they encountered a new problem — — Policy obstacles to the transformation of scientific and technological achievements.
"As far as the transformation of scientific and technological achievements is concerned, it is necessary for the deep participation of source innovation researchers to realize the transformation. However, the management of many universities and research institutes still needs to be improved. While shouting support for the country’s industrial upgrading, they have managed to kill scientific and technological personnel. " Cao Jianguo said.
Fortunately, the school later supported Zhang Yueming’s transformation of technological achievements. Xie Hui, secretary of the Party Committee of Beijing University of Technology, told reporters: "In recent years, the CPC Central Committee and the State Council have issued a series of reform measures on science and technology management, and the school has also established a series of supporting policies to strengthen the transformation of scientific and technological achievements in the school. Beijing University of Technology incorporated the transformation performance of scientific and technological achievements into the evaluation indicators of teachers’ performance, positions and titles and improved the weight of assignment. Zhang Yueming and other researchers successfully promoted the title of professor through the transformation performance of scientific and technological achievements such as robot RV reducer. "
Lack of funds to continuously support the expansion of production scale is the third "mountain" that many innovative products are difficult to overcome in marketization.
Fortunately, Yizhuang Guotou and Jingcheng Holdings threw an investment olive branch to Zhang Yueming’s team. Now, a new factory in Shijiazhuang, which applies Zhang Yueming’s innovative technology, has been established, with an annual output of 50,000 sets. The road to localization of RV reducers is rapidly spreading, and China enterprises are striding forward to catch up with Japanese monopoly enterprises.
Competition in the international market is another "mountain" that they need to climb.
"It is foreseeable that its products will encounter a series of problems such as price cuts by Japanese companies. This requires expanding production scale, reducing costs and improving market competitiveness. " Cao Jianguo said.
"Zhang Yueming’s team’s independent innovation of RV reducer has achieved a breakthrough from basic research to industrialization, which is very rare. This is of great significance for forcing the price of Japanese reducers to be reduced, making the core technology of domestic robots no longer dependent on imports, improving the competitiveness of domestic robots and participating in international market competition. " Zhaojie said.
Han Xiucheng, director of China National Intellectual Property Administration Intellectual Property Development Research Center, said: "To build a good ecological environment for innovation and entrepreneurship, we should not only learn from international experience, but also have China characteristics, and need the joint participation of researchers, enterprises, universities, patent departments, financial institutions and venture capitalists. Researchers pay attention to source innovation, schools give policy support to release the innovation vitality of researchers, venture capitalists do a good job in pilot projects, patent departments give technical protection, financial investment institutions give financial support, enterprises realize product marketization, and all parties work together to explore a market-oriented path. Accelerate the transformation of scientific and technological achievements into real productive forces and drive the industrial transformation and upgrading of the whole country. " Han Xiu Cheng said, as far as the current international and domestic environment is concerned, the whole country should unite as one and fight hard the key core technologies. We must fight this battle and we will certainly win it.

At 20: 09 on December 4, 2022, the return capsule of Shenzhou 14 manned spacecraft landed successfully in Dongfeng landing field, and the mission was a complete success. From the hot summer to the cold winter, the Shenzhou 14 astronauts successfully completed all the established tasks by team, creating a number of "firsts". Let’s trace the flying footprint of Shenzhou XIV and review the half-year space journey of the "busiest crew".
Set out to fly, with firm steps
At 7: 54 on June 5, 2022, the astronauts of Shenzhou 14 manned mission went out in groups at Wentiange Square in Jiuquan Satellite Launch Center, and astronauts Chen Dong, Liu Yang and Cai Xuzhe were ordered to go out.

At 10: 44, the Shenzhou 14 manned spacecraft was successfully launched, and three astronauts were successfully sent into space.

Successfully docked and settled in the "Tiangong"
At 17: 42 on June 5, the Shenzhou 14 manned spacecraft successfully docked at the radial port of Tianhe core cabin, and the whole docking process lasted about 7 hours.

At 20: 50, the Shenzhou 14 crew successfully entered the Tianhe core cabin and became a new group of owners of the "Space House".

Establish a manned environment and organize the "Space House"

In order to carry out work and normal life as soon as possible, the crew quickly put into the on-orbit resident environment setting, carried out microbial sampling, installation, debugging and maintenance of various equipment, and successively entered the Tianzhou-4 and Tianzhou-3 cargo ships to sort out and transfer materials, creating a comfortable and livable space home.

"Ask for Heaven" and greet "New House"
On July 24, the space station’s experimental capsule was successfully launched, and Shenzhou 14 watched the whole launch in orbit.

On July 25th, Chen Dong, commander, opened the hatch of the space shuttle, and successfully entered the space shuttle by crew. This was the first time that an astronaut from China entered the scientific space shuttle in orbit.

Third time out of the cabin, a new record
This mission has created a new record of three exits from a flight mission. On September 2, Shenzhou 14 crew completed the first outbound activity from the airlock cabin of the Inundation Experimental Module assisted by a small robotic arm, and verified the main path of autonomous transfer outside the Inundation Experimental Module for the first time.

On September 17, the crew left the cabin again after a lapse of half a month, and completed the tasks such as the installation of extravehicular facilities and equipment and the verification of extravehicular rescue. Together with the crew, the vast universe of Xinghe witnessed the rapid development of the China Space Station.

On November 17th, the crew successfully completed the third extravehicular activity. During the extravehicular activity, the astronauts built an "overpass" that walked outside the cabin between three cabins, and tested the ability to work with the combined manipulator for the first time. This was the first extravehicular activity after the basic configuration of the space station "T" was assembled.

Teaching in space, asking for the truth
On October 12th, the third lesson of "Tiangong Classroom" was held in the "New Classroom" for the first time. Three new "space teachers" introduced a series of interesting phenomena and principles of scientific experiments in the working and living scenes and microgravity environment in the experimental cabin, presenting another wonderful space science class for the majority of teenagers.

The practice (test) is not stopped, and the training is not stopped.
During the mission, Shenzhou 14 crew carried out a lot of inspection and testing of the space station platform, equipment maintenance, maintenance verification, material management and station management, unlocked and installed multiple experimental cabinets in two experimental cabins, and carried out a number of space science experiments and technical experiments as planned.

In addition to daily physical exercise, we also regularly carry out various professional and technical trainings such as manipulator operation, extravehicular activity operation, rendezvous and docking operation, emergency rescue and medical skills. The "busiest group" is well deserved.

"T" in the third cabin bears witness to history.
After the successful launch and successful transposition of Mengtian Experimental Module, on November 3, Shenzhou 14 crew successfully entered Mengtian Experimental Module, opening the "three-bedroom" era in Chinese space.

During the mission, the crew cooperated with the ground to complete the assembly and construction of the "T" basic configuration of the space station, and experienced 9 assembly configurations, 5 rendezvous and docking, 2 separation and evacuation and 2 transposition missions, which witnessed many historical moments of China’s manned space flight.

Space victory "joining forces", staged "six-party"
In the past six months, the Shenzhou 14 crew has not only witnessed history, but also made history. Chen Dong became the first astronaut in China to stay in orbit for more than 200 days.

On November 30th, the long-awaited Shenzhou XIV astronauts successfully opened the "home" by group, warmly welcoming relatives from afar to settle in the "Tiangong". The two astronauts of the "Victory Meeting" took a group and left a space photo in Chinese’s own "Space Home" that could go down in history.

Do one’s duty and return with honor.

After the handover with the Shenzhou-15 crew, on December 4th, the return capsule of the Shenzhou-14 crew landed successfully, and the three astronauts returned safely with full glory in the long-awaited event. The mission is over, but new tasks and challenges have just begun.

Congratulations on the successful completion of the mission by Shenzhou 14 crew.
China Space Station is always worth looking forward to!
Many friends suffering from cardiovascular diseases are very worried about the aggravation of their illness after being infected with Covid-19. For patients with cardiovascular diseases, especially those with hypertension, coronary heart disease, heart failure and after interventional therapy, prevention is the first priority. If there are no contraindications, COVID-19 vaccine should be actively inoculated.
What should patients with cardiovascular diseases do if they are infected with Covid-19?
First of all, don’t panic. At present, the symptoms of infection caused by Covid-19 Omicron mutant are relatively mild, so it is enough to deal with them actively. If you have persistent discomfort, you should go to the hospital for examination and treatment in time.
Some patients with coronary heart disease usually take lipid-lowering drugs, antihypertensive drugs or antiplatelet drugs step by step, and consider stopping taking these drugs after infection to "concentrate" on fighting Covid-19. This kind of practice is absolutely unacceptable. Blood coagulation tendency may occur after human body is infected with Covid-19. For patients with coronary heart disease, if the use of antithrombotic drugs is suddenly suspended, it is easy to form thrombus in a short time and induce myocardial infarction. If statins suddenly stop taking lipid-lowering drugs, blood lipids will also rise rapidly.
From the current clinical experience, only a high fever may have a certain impact on the treatment of a small number of patients with heart disease, and other treatment methods are relatively safe, such as commonly used drugs for clearing away heat and toxic materials and relieving muscle soreness, and no adverse reactions have been found after being combined with cardiovascular treatment drugs.
If infection occurs, patients with coronary heart disease can deal with various discomforts caused by COVID-19 infection. If you have fever symptoms, in addition to taking antipyretics carefully (for example, taking them staggered with other drugs, starting from a small dose when using antipyretics, etc.), you should also replenish plenty of water or choose physical cooling; If you have sore throat, avoid spicy food in your diet and use some buccal tablets to relieve discomfort; If you lose appetite or taste, you can eat more sour food. Daily advice is to eat more fresh fruits and vegetables.
Many hypertensive patients have increased blood pressure after being infected with Covid-19, fearing that this is caused by the virus attacking the cardiovascular system. In fact, there may be many reasons for blood pressure fluctuation, which may not be directly related to Covid-19.
After being infected with Covid-19, especially in the acute phase, the human body will have a stress reaction, and the heart beat will increase, thus pushing up blood pressure. Generally speaking, after the acute phase, this stress blood pressure increase will gradually ease. After infection, many people say that they are sore all over, have sore throat, and even feel uncomfortable and can’t sleep. These symptoms are also common causes of hypertension.
Finally, I would like to remind you that once patients with cardiovascular diseases have obvious chest tightness, chest pain and other symptoms, especially if they are not sure whether it is caused by Covid-19, they should go to the hospital as soon as possible without delay.
