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.

　　Guangming Daily (April 11th, 2021, 01 edition)

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.

Correspondent Ning Gongxin

More than 8,000 security personnel ensure the safety of the event.

The reporter learned from the press conference that in order to do a good job in the security of the 2023 Nanjing Marathon, the Nanjing police set up a special class for South Malaysia three months in advance, formulated and issued a general security plan, and started various preparatory work. Set up a field headquarters, and the public security, traffic police and other departments will work with the organizing committee of the tournament to carry out many field surveys to demonstrate, refine and improve the plan. On the day of the competition, the police will invest more than 8,000 security personnel at the starting point, the finishing point and along the route to undertake the security and traffic diversion tasks of the competition. The guardrail, hard enclosure and other facilities will be used for closed-loop control along the 42.195-kilometer track to ensure the smooth running of the competition.

In view of the temporary control of the race section during the marathon, in order to reduce the impact on citizens’ travel, Nanjing police combined with previous years’ security work experience to optimize and adjust the track. Li Peng, member of the Party Committee and deputy director of the Municipal Public Security Bureau, said, firstly, the track was controlled by sections, and the whole track was temporarily controlled and released by sections, which not only ensured the smooth running of the race, but also resumed the road traffic as soon as the stage was over. The second is to ensure public transportation. Elevations, tunnels and river-crossing passages in the city are basically unblocked, and the entire subway line runs normally, ensuring that people leaving the city, crossing the river and going to airports and stations are not affected. The third is to set up crossing points on the track, and set up transverse crossing points at 76 light-controlled intersections along the track, with an average of 550 meters. According to the density of athletes in the track, pedestrians and non-motor vehicles on both sides of the track will be organized in an orderly manner. The fourth is to provide consulting services. The traffic control department will announce the event hotline, provide peer-to-peer consulting services to citizens with travel needs, help plan travel routes, avoid the control sections during the event, and minimize the impact of event security on urban operation.

No drones are allowed to fly across the track.

On the day of the race, the public can enjoy the style of marathon runners along the track. The police advised the public to avoid crowded areas such as the finish line, obey the management of on-site duty personnel and watch the race in a civilized manner. No social vehicles are allowed to park along the track, no social vehicles are allowed to park along the elevated roads and pedestrian overpasses, and no pedestrians are allowed to stay and watch the game. On the premise of not affecting the safety of athletes, security personnel at some intersections will organize pedestrians and non-motor vehicles to cross the track in an orderly manner according to the situation of on-site events, and ask the general public to consciously obey the command and management of on-site duty personnel to prevent the occurrence of forced entry into the track.

On the morning of November 5, Nanjing police took the lead in conducting security drills. "On the day of the 12th race, the roads passing by the track will be blocked section by section. Please listen to the instructions of the police on duty to ensure the safety of the participants and themselves. At the beginning, end and along the track, drones are prohibited from flying, and they will be investigated as soon as they are found. " Kong Lingzhao, deputy head of the Public Security Detachment of the Municipal Public Security Bureau, said.

The reporter learned from the press conference that this year’s South Malaysia race will be held from 7:30 to 14:00 on November 12, with a long time span. The police advised the public to plan their trips in advance, avoid the time and sections of the competition control, and try to travel by subway and other means of transportation. Duan Ninghui, deputy head of the Traffic Police Detachment of the Municipal Public Security Bureau, said that during the competition, motor vehicles, special work vehicles, construction machinery vehicles and hazardous chemicals transport vehicles were prohibited from passing in the area south of the Yangtze River and around the city highway (excluding this road) in Nanjing, and the original traffic policy was maintained around the city highway.

At the same time, vehicles that originally held the truck restricted area pass were suspended from driving in the above-mentioned restricted areas and sections. The following six types of vehicles, after reporting to the traffic control department, enter and leave the restricted area according to the specified time and route: the people in this city are in urgent need of life that day; Marathon events must be used; It must be used to maintain the public order of marathon events; Used for emergency rescue and disaster relief; Involving national, provincial and municipal key projects that really need to be used that day; Involving national political, military, diplomatic and other needs.

People with special needs should plan their trip in advance.

Jin Qingyi, deputy detachment leader of the Traffic Police Detachment of the Municipal Public Security Bureau, said that citizens with special needs such as marriage, classes, exams and urgent important activities on that day can plan their trips in advance according to the bypass route announced by the police to avoid the road of competition control. On the day of the competition, citizens who plan to drive to the Great Hoonji Ruins Park, the Presidential Palace, Xuanwu Lake and other scenic spots try to avoid the morning time. The traffic control department will open the 12123 Nanma consultation hotline from November 6 to 10 (Monday to Friday) to answer questions about public transportation on the day of the competition. The working hours are 9: 00-11: 30 and 14: 30-17: 30 every day.

This year, South Malaysia set up a standard marathon track and a mini-healthy running track, with separate starting and finishing points, and there is no large parking lot around the starting point. The police suggested that the majority of the contestants take the subway to the starting point, and the subway will run at 5:30 in advance on the day of the competition. Participants can take the bus and subway for free with their directory. Tang Bin, a member of the Party Committee of the Public Security Detachment of the Municipal Public Security Bureau, said that in order to better cope with the sudden physical discomfort of athletes, the police recruited 100 policemen with good physical fitness and work experience to protect the runners, and the runners were closely connected with the medical staff in the track, so that all kinds of emergencies could be handled in time.

　 　 Why do you choose to watch a movie? Have you ever been shocked by a seemingly "virtuous" movie? Xiaobian is lucky to have experienced this sense of shock caused by watching movies. Of course, for spending time watching an "old" movie with no new ideas, the movie that can really refresh the movie concept has the charm of "welcome". Not only do these films make you shout "My God" after watching them, but the films themselves are full of rich connotations. You can even talk about this film with your friends. Of course, the most important thing is that you will once again feel a fact that has been confirmed countless times — — The movie is really a seductive shampoo.

Happy ending

1, "Happy Ending" Stastny konec 1967

Director: Oldrich Lipský

Length: 71 minutes

　 　 When I first watched this movie, I thought my computer was broken, but after watching it, I found that my head was burnt out. Although the film is only 71 minutes long, it tells two stories, and it is completely backwards! At the beginning, we saw that the chopped head returned to the protagonist’s body, and then we followed him backwards, gradually understanding why he committed the crime and gradually returning to the most beautiful and good beginning. According to the sequence of the movie, this is a happy story, but if we really think backwards and imagine that the cookies on the table are eaten one by one like our normal life, we realize that this movie is a complete tragedy in the normal sequence. If you still don’t understand, think about your happiest time and walk back step by step. This movie gives you this idea, and it will remind you how you make a mess of your life. This is your life, WTF!

Holy mountain

2、 The Holy Mountain 1973

Director: alexandro jodorowsky

Length: 114 minutes

　 　 Zo dulov’s Holy Mountain is rich in connotation, on the one hand, it has the cloak of religious theology, on the other hand, it shows political, gender, philosophy and other issues. All these show that the director actually reflects the complex ecological circle in which people live through movies. However, if you think this film is the same as other "magic films", it is your mistake. When exploring all the way to find a sacred mountain that can live forever, the whole film has become the epitome of society and life. However, Zodulov denied the authenticity of the film content as "life content" when he showed the sacred function of the film to guide people to return to life. As a result, the most explosive scene of the film was staged — — "Is this real life? No, it’s just a movie. The camera pulls back. " OMG！

Fun game

3、 Funny Games 1997

Director: michael haneke

Length: 108 minutes

　 　 "Fun Game" is not a movie that will make people feel comfortable after watching it. On the contrary, it will make people feel tormented in the process of watching it. The suffering is not due to the quality of the film, but the violence and darkness of social reality shown by director michael haneke through the film, which is completely breathless. What’s more, this time it was a dose of Double Kill. Director Haneck’s action of breaking the dimensional wall through the villain Paul winking at the camera and talking to the audience is enough to make the spectators angry. It never occurred to me that when the victim Ann shot and killed Paul’s companion Pete, Paul actually used the TV remote control to put the whole movie back before Ann picked up the gun! This is Paul’s fatal joke on Ann, and it is also Paul’s mockery of the audience’s only hope — — The dark side of society has never been a fairy tale play house. It is conceivable that only bad luck awaits Ann, but the two villains feel at ease to find the next participant in their bad game. WTF！

Psychological game

4、 Mind Game 2004

Director: Masaaki Yuasa

Length: 103 minutes

　 　 The most basic element of a Masaaki Yuasa powder is to be dead set on love, and the response to its works has always been "Wow, great!" And also call his painting style "exquisite visual system". In the first few minutes of reading his works, people will basically suspect that the creator is a psychopath, but the process of watching is actually a process of assimilation bit by bit, so once he falls, he can’t extricate himself. Although there are general plots and characters in "Psychological Games", Masaaki Yuasa didn’t restrain his nerves at all. A story of living and escaping in a fish’s belly was added to all kinds of fragments like dreams and subconscious that he could think of, and he also switched between real people, three-dimensional and two-dimensional, with dazzling light and messy style. Perhaps as a madman, Tang Qian’s purpose is to drive the world crazy.

Blessing

5、 สุดเสน่หา 2002

Director: apichatpong weerasethakul

Length: 125 minutes

　 　 Fans’ attitude towards Thai director Abichabang is almost as polarized as Masaaki Yuasa’s, and they either can’t extricate themselves from it or don’t touch it. There are few centrists in between, because such directors often have extremely strong personal styles and don’t change easily. "Blessing" is the first work of Abichabang, from which the consistent dichotomy structure in his films began, and the opening move of half time was also used for the first time here, and the first half of the story was ridiculed as "long opening". This practice is not uncommon in later works, and Jia Zhangke also used this method in the film, taking the title as the boundary between 1999 and 2014.

Uncle bumi who can recall past lives

6、 2010

Director: apichatpong weerasethakul

Length: 114 minutes

　 　 Like "Blessing", the film also separates urban life from stepping into the jungle with a dichotomy structure and a belated title. After winning the Palme d ‘Or for Abyssa, the director repeatedly mentioned that his motherland was in a state of war, and the western media also called it "the victory of politics over art". However, Abyssa’s politics is also extremely artistic, because of its obscure symbols and too stagnant lenses. The most amazing thing in the film is the lust that transcends the barrier between species instinctively. The great leap of species is the ancient princess in memory and a catfish in a pond. In addition, the boundary between humans and primates was blurred when they returned to the jungle. Uncle Bumi’s youngest son appeared as a long-haired black monkey.

A day of floating life

7、 Life in a Day 2011

Director: kevin mcdonald

Length: 95 minutes

　 　 This movie comes from a great idea. YouTube invites netizens all over the world to record their daily life trivia and answer some simple questions on July 24th, 2010 with a video camera. Under the arrangement of documentary director kevin mcdonald, these huge video materials finally turned into this film. We will see all kinds of people, looking at the human day from the perspective of God, and finally sighing in tears with the attitude of a god with humanity. However, the poison of this movie is that when you are deeply moved and really want to record the poetry in your life, you will find yourself cheated, just as one person in the movie said (she also wandered around with a camera for a day), "I looked forward to it for a day, but nothing happened" (you must have felt the same way on December 21, 2012). Think about it again. This movie is 1.5 hours out of 4,500 hours. Although contrary to the song, life is the present, and the distant fields are others’, but you get at least three ten thousandths of poetry.

Love finally cuts: ladies and gentlemen

8、 2012

Director: George Paulson

Length: 84 minutes

　 　 "The Final Cut of Love: Ladies and Gentlemen" is not a regular love movie, it can be said that it is a long collection of movie clips (shots). The director not only shows the amount of films he watches (max level), but also splicing these fragmentary materials from different sources into a complete love story. When watching a movie, because the lens editing is interesting and fluent, you will enter the enjoyment state of looking for a movie, looking for a male god and looking for a goddess to find all kinds of interesting stalks. But when this story is complete and "old-fashioned" film ends, you may find that wow… It turns out that "love" can make an ordinary person have more than three ten thousandths of poetry, and the spliced film also has charm. And I not only have a surprise cry when I watch the movie, but also a warm and humid liquid in my eyes.

Reality

9. "Reality" Réalité 2014

Director: Quentin Dupieux

Length: 95 minutes

　 　 It is difficult to define "Truth" by conventional logic, but it happens to be another kind of truth. When it is fake, it is true and false, but blindly looking for truth becomes another kind of absurdity. The story of "Reality" is a kind of "drama in the play" structure, but compared with the general drama in the play, the story is more intertwined, and it is even more difficult to distinguish which part is the drama, the little girl and the video tape are the drama, while Zhan Sen in the video tape is the drama in the play, and Zhan Sen in the play can be connected with the investors of the drama appearance outside the play by telephone. At the end of the plot, it gradually returned to the starting point of the plot. Zhan Sen talked with investors on the balcony, and the talented and crazy documentary veteran walked out of the front door, which was really as ingenious as Mobius’ two-dimensional single-sided ring structure. The structure of the film is wonderful, but the real life it expresses is actually as boring as a stagnant pool.

　　Original title: How to achieve zero energy consumption and zero carbon? The reporter walked into the planning exhibition hall of the sub-center to explore the first "double zero" building in China.

At the intersection of the five rivers in the city sub-center, the planning exhibition hall of the sub-center, the first "double zero" building with steel structure and full curtain wall system in China, is in full swing.

　　"Double zero" means zero energy consumption and zero carbon. The building area of the museum is 7583.78 square meters, with an annual energy consumption of 315,000 kWh, an annual power generation of 900,000 kWh, and a comprehensive energy-saving rate of 100%. The annual carbon emission is about 370.73 tons, and the annual total carbon reduction is 724 tons (about equal to the annual carbon sequestration of 1811 mu of forest), and the whole building is "carbon neutral". So, what kind of technology ensures the realization of the "double zero" goal?

　　There is a "super charging treasure" on the roof.

　　The sloping roof of the planning exhibition hall is not paved with traditional pottery tiles, but with photovoltaic tiles with a frosted dark brown texture like ancient bronzes, while the flat roof is provided with grid-like brown glass-based photovoltaic panels. Photovoltaic building integration is the first key word to realize "double zero" building.

　　"Photovoltaic tiles are not only easy to install, but also can be used for heat preservation, heat insulation and power generation. At the same time, they have good low-temperature impact resistance and excellent corrosion resistance." Xu Youyue, project manager of plot 160 of the Urban Sub-center of China Construction First Bureau, introduced that about 6,000 square meters of photovoltaic equipment have been laid in the 160 plots where the exhibition hall is located, and the annual power generation can reach 150 kWh/square meter. Photovoltaic power generation technology is like a "super charging treasure", which continuously converts solar energy into electric energy. The electric energy generated by photovoltaic tiles adopts the mode of "spontaneous self-use+surplus electricity online", thus achieving the goal of "zero-carbon exhibition hall and low-carbon office area" as a whole. At present, photovoltaic roofs have concentrated on welding and hanging tiles.

　　At the same time of external "charging", high-performance thermal insulation materials and high-performance green waterproof gas barrier with air tightness of 8 and water tightness of 6 put a "collar" on the planned exhibition hall, making the exhibition hall "frozen in winter and not hot in summer". "The thickness of the external wall insulation material is generally 100 mm to 130 mm, and we have made the thickness of the rock wool board of the exhibition hall 210 mm, which has better thermal insulation effect and can reduce the annual energy consumption of the exhibition hall from 613,800 kWh to 315,000 kWh. Compared with the annual energy consumption of the benchmark building of 670,000 kWh, the energy saving rate of the building itself is 53%." Tang Jinqi, production manager, said that under the joint action of photovoltaic "super charging treasure" and "collar", the comprehensive energy-saving rate of the exhibition hall reached 100%, filling a gap in the domestic zero-energy building system.

　　"Building blocks" type building is green and environmentally friendly.

　　In the construction site of the planned exhibition hall, the assembled curtain wall glass and stone are piled up orderly on the green dust-proof net on the ground, and the construction site is clean and tidy. There are no sparks of material cutting and piles of construction waste, which is completely different from the traditional impression of the construction site. Xu Youyue said: "The exhibition hall adopts assembled building technology, which effectively reduces the waste of materials and garbage on site."

　　Assembled building technology is the second key word to realize "double zero" building.

　　The prefabricated building technology is modular and customized cutting in the factory in advance, and then transported to the construction site for "building blocks" combined installation. The technology is simple, green and environmentally friendly, but the error of prefabricated components and the precision of on-site construction are very high. "The construction error of cast-in-place concrete structures is often measured in centimeters, and our prefabricated building technology has improved the precision control from millimeter level to meter level."

　　"Double Zero" construction technology can be copied.

　　"Smart brain" is the third key word to realize "double zero" architecture. The innovation of the sub-center planning exhibition hall project adopts a series of hard-core intelligent technologies such as big data and cloud computing, which empowers the building with intelligence and creates a "super brain" of intelligent construction, ensuring the "double zero" operation of the museum in the whole life cycle of design, construction, maintenance and operation.

　　"In order to efficiently manage workflow and data storage, we independently developed and applied a fine chemical engineering information management system based on blockchain, and achieved a’ zero’ breakthrough in’ building+blockchain’." Xu Youyue introduced that in the blockchain management system, all data and project files collected and uploaded through intelligent devices such as the Internet of Things, 3d scanner and lofting robots have their own "ID cards", which cannot be tampered with once stored, ensuring the safety, truthfulness and reliability of project data; The expert database embedded in the system can form a special solution for the project. In-building Internet of Things technology and smart energy flexible management mode can realize the intelligent linkage of temperature and humidity control and weather environment, and the intelligent linkage of building environment and humanized demand, which embodies the innovative concept of intelligent building adapting to and utilizing nature. Moreover, technicians deeply develop and continuously optimize AI intelligent algorithms, and AI gradually has the ability of "continuous learning", and the quality and efficiency of system review will continue to improve.

　　At present, the facade curtain wall of the project has been completed, and this "double zero" building with three floors above ground and underground has taken shape. “

　　Sub-center planning exhibitionThe museum shows the cultural background and characteristics of the sub-center in the form of square, elegant and simple architecture. This’ Double Zero’ exhibition hall is world-class, and shows the world a brand-new zero-carbon building form! Tang Jinqi said that with the continuous deepening of construction, the construction technology and experience of "double zero" buildings have been accumulated and have strong reproducibility, which can provide more possibilities for "double zero" construction projects to blossom everywhere in the country.
