Xinhua News Agency, Beijing, September 6 (Reporter Gu Tiancheng) added new research evidence, updated relevant policies and measures for influenza prevention and control, and updated the types of influenza vaccines listed and used in China in 2023-2024 and vaccination suggestions … The reporter learned from the China CDC on the 6 th that the China Center for Disease Control and Prevention has recently issued the "Technical Guide for Influenza Vaccine Vaccination in China (2023-2024)", which provides guidance for better guiding influenza prevention and control and vaccine use in China.

Experts from the Infectious Diseases Management Office of China CDC said that influenza is an acute respiratory infectious disease caused by influenza virus, which is seriously harmful to human health, and people are generally susceptible to influenza virus. High-risk groups such as pregnant women, infants, the elderly and patients with chronic diseases are more harmful after being infected with influenza, and influenza outbreaks are prone to occur in places where people gather, such as schools, kindergartens and nursing homes.

Vaccination against influenza every year is an effective means to prevent influenza and reduce the burden of influenza-related severe illness and death. The new version of the guide is clear, and it is recommended that all people who are ≥6 months old and have no vaccination contraindications should be vaccinated against influenza. Priority is given to the timely vaccination of key and high-risk groups including medical personnel, the elderly aged 60 and above, people suffering from one or more chronic diseases, children aged 6 to 59 months, their family members and caregivers.

According to the guidelines, in terms of vaccination times, it is recommended that children aged 6 months to 8 years old who have not been vaccinated with influenza vaccine before should be vaccinated with 2 doses at intervals of ≥4 weeks; In 2022-2023 or before, one dose or more of influenza vaccine was inoculated, and then one dose was inoculated; Children and adults aged 9 years and above need only be vaccinated once regardless of whether they have been vaccinated with influenza before. For live attenuated influenza virus vaccine, no matter whether it has been vaccinated with influenza vaccine or not, only one dose is given.

The guidelines also suggest that all localities should carry out vaccination as soon as possible after the vaccine supply is in place, and try to complete vaccination before the local influenza epidemic season. For people who can be vaccinated with different types or different manufacturers of vaccine products, the recipients or their guardians can voluntarily choose to vaccinate any kind of influenza vaccine, and there is no priority recommendation.

　　People’s Forum Network September 9 (Wang Shuang) A good business environment is an important foundation for economic development and an important factor in determining the competitiveness of cities, regions and even countries. On November 1, 2018, General Secretary of the Supreme Leader made a speech at the symposium of private enterprises, proposing that we should do a good job in six aspects of policy measures, create a better development environment for the private economy, help the private economy solve the difficulties in its development, support the reform and development of private enterprises, turn pressure into motivation, let the innovation source of the private economy fully flow in, and let the private economy create generate with full vitality.

　　Chongqing has made some achievements and explored some innovative experiences around promoting high-quality development and thoroughly implementing the new development concept. In order to fully implement the spirit of General Secretary Supreme Leader’s speech on "creating a fair and transparent business environment and promoting the sustained and healthy development of China’s economy", Chongqing Municipal Party Committee and Municipal Government attached great importance to optimizing the business environment. In view of the outstanding problems reflected by the market and enterprises, we deepened the "streamline administration, delegate power, strengthen regulation and improve services" reform as the starting point, reformed and innovated the system and mechanism, further optimized the business environment, and continuously stimulated social vitality and creativity, and achieved good social effects.

　　On September 5 -6, the online theme publicity campaign of "Private Economy and High-quality Development in the New Era" visited Chongqing to discuss how to further optimize the business environment and promote the high-quality development of the private economy.

　　Optimize the government environment and strive to provide more detailed and efficient government services.

　　On March 4, 2016, the General Secretary of the Supreme Leader stressed at the joint meeting of members of the Democratic National Construction Association and the Federation of Industry and Commerce during the two sessions of the National People’s Congress that all localities and departments should refine quantitative policies and measures and formulate relevant supporting measures, so that the policies on encouraging, supporting and guiding the development of the non-public economy can be implemented in detail, so that private enterprises can truly enhance their sense of gain from policies.

　　In recent years, a series of policies and measures, such as Opinions on Comprehensively Optimizing the Business Environment to Promote the Development of Private Economy, Implementation Opinions on Further Creating a Healthy Growth Environment for Entrepreneurs, Promoting Excellent Entrepreneurship and Giving Full Play to the Role of Entrepreneurs, and Several Policies and Measures to Further Support the Healthy Development of Enterprises in the Real Economy, have been introduced one after another, and various municipal departments have also introduced implementation measures. The business environment of the whole city has been continuously improved, and the sense of acquisition of private enterprises has been continuously enhanced.

　　"In three days, I got a loan of 200 thousand yuan."

　　Wang Qiaodao, general manager of Chongqing Nandian Technology Co., Ltd. (hereinafter referred to as "Nandian Technology") talked about the business environment in Chongqing, which was quite emotional. In October, 2011, Nandian Technology was established under the condition of "no funds, no resources and no products". It started its business with a subsidy of 42,500 yuan from Chongqing municipal government and a personal credit loan of 120,000 yuan. In the process of starting a business, government departments at all levels have helped Nandian Technology for a long time. The Science and Technology Commission of Jiangbei District of Chongqing has given support to the application of high-tech products and innovative projects, and the relevant departments of Jiangbei District have given preferential policies and loan application assistance for a long time, which has greatly facilitated the development of local small and micro enterprises. Wang Qiaodao said that after truthfully reflecting the financial difficulties to the local government departments, "the government departments contacted Chongqing Bank on the same day, and in three days, I got a loan of 200,000 yuan. In that year, I developed the second generation of smart helmets, and the company achieved profitability." Nandian Technology has experienced rapid growth this year due to the investment and accumulation in scientific research and development in the early stage. With the support of the government, Wang Qiaodao is full of confidence in the development of the enterprise. He expects that the sales this year will exceed 15 million.

　　Optimizing the legal environment for private entrepreneurs to eat "reassurance"

　　The Central Economic Work Conference held in December 2018 pointed out that it is necessary to enhance the vitality of micro-subjects, give play to the subjective initiative of enterprises and entrepreneurs, establish fair, open and transparent market rules and a business environment ruled by law, promote positive incentives and survival of the fittest, and develop more high-quality enterprises.

　　To create a business environment ruled by law, we must adhere to the rule of law in the operation of power, further transform government functions, fully clarify the relationship between the government and the market, respect the laws of the market economy, and adjust the interests of various market entities within the framework of the rule of law through market-oriented means. By deepening the "streamline administration, delegate power, strengthen regulation and improve services" reform, optimizing public services, promoting the reform of the examination and approval system, we can truly improve administrative efficiency, innovate administrative law enforcement methods, and accelerate the construction of a service-oriented government.

　　Zhou Chengwen, deputy inspector of Chongqing Municipal Market Supervision Bureau, said that Chongqing vigorously promoted intellectual property protection. Strengthen the supervision of intellectual property law enforcement, deploy and carry out the "iron fist" action of intellectual property law enforcement, increase the protection of e-commerce, key commodity trading markets, foreign investment, key people’s livelihood, large-scale exhibitions and other fields, and help 50 enterprises such as Jiang Xiaobai and Yu Xinou to guard against intellectual property risks.

　　At the same time, Zhu Jiang, director of the Department of Economic Restructuring of Chongqing Municipal Development and Reform Commission, said that the construction of the credit system would be further promoted in an all-round way. A credit "red and black list" system has been established in 30 fields, including government procurement, transportation, environmental protection, tax evasion and fraud, and quality violations. A total of more than 330,000 "red and black list" subjects have been identified, and the "red and black list" has been triggered and joint rewards and punishments have been implemented for more than 37,000 times, basically building a big pattern of credit joint rewards and punishments.

　　Yan Hongwei, political commissar of the Economic Investigation Corps of Chongqing Public Security Bureau, stressed that it will serve private enterprises accurately, take serving the development of private economy as an important starting point to build a "pro-"and "clean" political and business relationship and deepen the "streamline administration, delegate power, strengthen regulation and improve services" reform, actively implement measures such as "doing it online", "doing it right away" and "running at most once" to create a high-quality business environment.

　　"Stronger supervision and better service"

　　Zou Yu, executive vice president of Chongqing Hua Xiong Industry (Group) Co., Ltd. stressed that in recent years, there have been three changes in Chongqing’s business environment: one is that the efficiency of functional departments has been significantly improved, and there is no phenomenon of eating and getting cards, and the sense of acquisition and satisfaction of enterprises has been greatly improved; Second, the reform of the administrative examination and approval system has been further promoted, especially in streamline administration, delegate power, strengthen regulation and improve services, where supervision is stronger and services are better, which has stimulated the vitality of the private economy to a greater extent; Third, the technological environment for enterprises’ innovation and entrepreneurship is more open. Chongqing has introduced a series of technologies to encourage technological innovation, which has enhanced the regional core competitiveness.

　　Huang Li, the legal representative of Chongqing Ruigao Medical Industry Development (Group) Co., Ltd., also said that in the process of high-quality development of enterprises, leaders of relevant departments will take the initiative to come to the door to understand the truth and personally study and help, so that enterprises can fully feel the support of the government. Enterprises can settle down and achieve steady development in a pro-Qing political and business relationship environment.

　　Optimize the open environment and stimulate the vitality of market players

　　The General Secretary of the Supreme Leader stressed that it is necessary to do a good job in encouraging, supporting and guiding the implementation of the development policies of private enterprises, especially small and medium-sized enterprises, and to stimulate the vitality of various market players. The main body of the private economy is small and medium-sized enterprises. We have always unswervingly promoted the development of small and medium-sized enterprises, accelerated the improvement of incentive policies for the development of small and medium-sized enterprises, and constantly enhanced the endogenous power of the economy and the vitality of market players.

　　Fu Zonglun, director of the Private Economy Development Service Department of Chongqing Economic Information Commission, said that Chongqing is focusing on "transformation and upgrading" to promote high-quality development. Actively promote scientific and technological innovation, always put scientific and technological innovation in an important position in the transformation and upgrading of industrial economy, guide enterprises to establish R&D reserves, build municipal enterprise technology centers, key laboratories of industry and informatization, and new enterprise R&D institutions, and strive to enhance the innovation ability of enterprises.

　　“Strive for development through innovation and embark on a confident road of innovation and entrepreneurship. "

　　Guided and driven by Chongqing’s "going out" and other foreign investment platforms, Chongqing Zaisheng Technology Co., Ltd. (hereinafter referred to as "Zaisheng Technology") stepped up the pace of nationalization, invested in Italy’s Simon Fabrizi Company in July 2016, successively set up R&D design centers in Europe, and introduced a series of international technical talents and R&D design teams. With the support of Chongqing’s policy dividend, Zaisheng Technology actually enhanced its brand influence and gradually became global. Zaisheng Technology has maintained a rapid growth trend in recent years. In the first half of 2019, it achieved sales revenue of 616 million yuan, up 11% year-on-year, and net profit increased by 37%. "As a member of the local private economy, it is thanks to Chongqing’s efficient, transparent, fair, healthy and stable business environment that Zhongsheng Technology will seek innovation in development, seek development through innovation, and embark on a confident road of innovation and entrepreneurship." Yang Jinming, vice president of Chongqing Zaisheng Technology Co., Ltd., said excitedly.

　　On November 5, 2018, General Secretary of the Supreme Leader emphasized in his keynote speech at the opening ceremony of the first China International Import Expo that "the business environment is only better, not the best." This has also sounded the clarion call for China to create a world-class business environment in the new era.

　　"Planting buttonwood will attract phoenix habitat". Creating a world-class business environment is an important part of the government’s provision of public services, and it is also an important foundation and key link to achieve high-quality development. With the continuous optimization of Chongqing’s business environment, Chongqing’s private economy will continue to develop steadily.

　　[Global Times comprehensive report] "The Syrian army entered Raqqa province for the first time after two years" — — After the Iraqi army concentrated heavily on attacking Fallujah, an important stronghold controlled by the extremist organization "Islamic State" (IS), the battlefield against IS in Syria also received good news. According to Agence France-Presse reported on the 5th, Syrian Human Rights Watch, a British-based organization, said that under the cover of air strikes by Russian troops, Syrian government forces had invaded the eastern province of Raqqa dominated by IS on the 4th, and the front line was 80km away from the city of Raqqa, the capital of IS. In addition, the Syrian opposition and the Iraqi army supported by the United States also launched offensives against IS in different regions.

　　Agence France-Presse said on the 5th that this is the first time that the Syrian army has entered Raqqa province since its fall in 2014. In June 2014, the "Islamic State" announced the establishment of a "country with a combination of politics and religion", won Raqqa from the Syrian opposition and "established its capital" to implement Islamic law. Since then, IS has almost completely occupied Raqqa province. At the end of May this year, the Syrian opposition "Syrian Democratic Forces Alliance" supported by the United States launched a military operation in the northern part of Raqqa province, and IS militants retreated to Raqqa. On June 1, the Syrian government forces also began to launch a recovery operation in Raqqa province. According to the Syrian Human Rights Watch, at least 26 IS elements were killed, and 9 people were killed in the Syrian government.

　　Russian satellite news network said on the 5th that the Syrian army successfully crossed the border of Raqqa province from the southwest with the support of the Russian Air Force. The BritISh Broadcasting Corporation (BBC) said that in the north of Raqqa, the "Syrian Democratic Forces Alliance" is believed to have deployed 30,000 troops to expel IS armed forces. US officials estimate that there are about 3,000 to 5,000 IS militants in Raqqa. According to reports, Russia has promised to cooperate with the Syrian opposition and the United States to attack. On the 4th, "Alliance" continued to approach Mambiji, another important stronghold of IS, and has captured more than 30 surrounding villages and towns. Mambiji, located in Aleppo province in northern Syria, is an important link connecting Raqqa province and the Syrian-Turkish border.

　　Qatar Al Jazeera said on the 5 th that at present, the eastern, northern and western parts of Raqqa province have been surrounded, but the south IS still connected with other important strongholds occupied by IS. Entering Raqqa province is an important progress, but it takes time to attack the city of Laqqa. Raqqa has a vast territory, so whoever holds Raqqa must be heavily guarded.

　　At present, there is no indication that there is cooperation between Syrian government forces and the opposition. Russia’s "Viewpoint" reported on the 4th that it would be of great military and symbolic significance if the city of Raqqa, known as the capital and base camp of IS, could be captured. Sabet Mohammed, a former Syrian military general, said that the occupation of Raqqa would divide the territory controlled by the Islamic State into several parts and cut off the supply of IS militants who surrounded Deir ez-Zor. He said that before the start of government operations, Russian bombers carried out large-scale bombing of IS positions. However, no matter how the situation develops in the future, in addition to the flag of the Syrian government, government forces will never allow the flag of any organization to be raised in Raqqa, including the "Syrian Democratic Forces Alliance".

　　As of the evening of the 5 th, neither the Syrian government nor the Russian official made a statement on the attack on Raqqa. The Global Times reporter saw in Syria that the local media was also very quiet. Therefore, some analysts believe that the low-key of all parties shows that either this news has yet to be confirmed, or the advantage of government forces is very weak. On the 5th, Syrian government forces supported by Russia launched a fierce battle with anti-government rebels in Aleppo. Western media claimed that 16 civilians were killed when government forces launched air strikes against Aleppo, while Russia claimed that terrorist organizations dispatched armored vehicles to shell civilian areas.

　　“‘ Islamic State ’ In the face of four-front operations, the Associated Press issued a document on this issue on the 5 th, saying that IS is facing attacks from four aspects: the Syrian government forces, the Syrian Democratic Forces Alliance, the Syrian rebels and the Iraqi army. Reuters said on the 5th that IS occupied the cities of Raqqa in Syria and Mosul in Iraq two years ago, calling themselves the capitals of Syria and Iraq, and declared that it would rule all Muslims in these areas. Recently, the Iraqi army has attacked Fallujah and Mosul, two major strongholds occupied by IS, and the Syrian army has advanced into Raqqa province in Syria, and IS is suffering a major blow. On the 4th, the Iraqi army announced the control of Sagravia in the north of Fallujah. However, the battle to recover Fallujah has progressed slowly, IS militants have fought back fiercely, and there are still tens of thousands of people trapped in the local area, which hinders the Iraqi army from continuing to advance.

　　The United Arab Emirates newspaper El Pais said on the 5th that the Iraqi armed forces advancing towards Fallujah will encounter strong resistance from IS, but it is widely believed that it is a matter of time before Fallujah is recovered. Fallujah has been the breeding ground of rebellion since the United States overthrew Saddam Hussein’s regime, and the United States and the Iraqi government have never really controlled the city. "Even if Fallujah IS recovered, the time and difficulty of taming the city is no less than defeating IS."

　　On the 4th, Russian newspaper Izvestia quoted Yuri Jining, an expert from Moscow Institute of International Relations, as saying that at present, all factions in Syria face a common enemy. Therefore, moderate opposition Kurds can cooperate with government forces to fight IS. Without the support of government forces, Kurds would be surrounded by the enemy. In order to jointly attack this enemy, the Syrian government has also made some concessions in consideration of the interests of the Kurds.

　　At the just-concluded shangri-la dialogue meeting, the Russian side also raised concerns about the Syrian situation. According to a report by RIA Novosti on the 5th, Russian Deputy Defense Minister Antonov asked the United States to respond to Russia’s proposal on cooperation in Syria at the "Xianghui". Russian Foreign Minister Lavrov said in a telephone conversation with US Secretary of State Kerry on the 4th that he was worried about the attempt to delay the resumption of negotiations between the Syrian factions. It is necessary to draw a clear line between Syria’s moderate opposition and the "National Front" terrorists as soon as possible. The complex situation in Syria requires Russia and the United States to jointly fight terrorist organizations.

● To help enterprises tackle key technical problems, Sichuan explored the establishment of the first large-scale scientific instrument sharing platform in integration of defense and civilian technologies, and promoted the open sharing of scientific research resources such as large-scale scientific instruments and equipment.

● Create innovative cooperation platforms. At present, there are 9 major scientific and technological infrastructures built and under construction in the province, ranking among the top in the country, with 151 national scientific and technological innovation platforms and 1,332 provincial scientific and technological innovation platforms.

● Promote the transformation of scientific and technological achievements. Sichuan strives to solve the "first mile" and "last mile" problems of scientific and technological achievements transformation, stimulate the vitality of scientific research in colleges and universities, and at the same time strengthen the transformation of achievements, avoid ineffective research and development, and "research" rather than "development"

First-line tidal observation

It is an important reform task entrusted to Sichuan by the CPC Central Committee and the State Council to systematically promote the comprehensive innovation reform experiment.

In August 2015, our province became one of the eight comprehensive innovation and reform pilot zones in China. Chengde Mian area, which has concentrated nearly 70% of the province’s scientific and technological strength, has taken on the heavy responsibility of promoting implementation. How to rely on the profound scientific and technological "internal strength" to accurately point out the "acupoints" of the transformation of scientific and technological achievements and create a set of beautiful "boxing methods" to promote industrial development through science and technology?

From May 9th, the report group of "Magnificent 70-year Struggle in a New Era —— Journalists Visiting the National Experimental Zone" walked from north to south along Mianyang, Deyang and Chengdu to visit the "Kung Fu Cheats" of Sichuan’s comprehensive innovation and reform experiment.

From static rotation

Open the glass door, help the laboratory technology to insert "wings" and break into the vast industrial sky.

On the afternoon of May 15th, Professor Li Jianjun from the School of Architecture and Environment of Sichuan University opened a message box to reporters in the laboratory. In addition to the scholar’s elegance, it is difficult to hide a capable temperament in him.

"There are many transactions, and they are complicated. Please forgive me." Li Jianjun said. A string of titles on his business card reminds reporters that he is not only the "big cow" of flue gas desulfurization technology in China, but also the operational responsibility of related industrial companies.

Flue gas desulfurization is mainly to convert sulfur dioxide into sulfur trioxide and then into sulfuric acid. Other technologies need to be carried out at a high temperature of more than 400 degrees, and the flue gas needs to be heated. After about 8 years of scientific research, by 2010, the Li Jianjun team has mastered a relatively mature flue gas desulfurization technology, which can be carried out at 50-200 degrees, with environmental protection and cost advantages.

However, the technical achievements have gone out of the laboratory to realize industrialization, but this thin "glass door" is not easy to pass. A slightly embarrassing question is: how to distribute the benefits brought by the results between teams and units? Also, can scientists be good managers of enterprises?

In 2016, Sichuan University promoted the innovation of the transformation mechanism of scientific and technological achievements, and explored the confirmation of duty inventions, that is, recognized the ownership share of scientific researchers’ personal invention inspiration, innovative ideas and realization ability in the final results. As for the team achievements in Li Jianjun, the team and the school distribute the benefits of the achievements transformation according to 85: 15.

Accordingly, the team members raised funds to set up a company, focusing on a link in the industrial application of this technology: the production of catalysts and related supporting services, and after its establishment, it realized an output value of 30 million yuan. "Now hire a professional manager to take care of the company so that the team can continue to focus on the main business." Li Jianjun’s tone is calm. "The school has not talked with the team about redistribution, and it needs to be improved in the refinement of the system."

Let the scientific and technological achievements "realize" and let the scientific research team study calmly. Mianyang’s approach is the same-set up relevant technology trading centers, use professional technical brokers to run errands for the scientific research team, and promote the evaluation, trading and financing of scientific and technological achievements. At present, the center has recruited 71 technical brokers nationwide, mainly responsible for collecting local technology supply and demand information.

Turn emptiness into reality

From patent to mass production, we make moves in the square inch of the transformation of results, which gives birth to "singles" experts in sub-sectors

Carefully picked up two small bottles of transparent liquid, and looked at the light source carefully … The two bottles of liquid with a price difference of twice could not be seen in the eyes of reporters. R&D personnel explained that because the luminous flux difference between the two bottles of liquid is 3%, "the high price can reach 10 thousand yuan per kilogram."

On the morning of May 10th, in the final test site of Mianyang Huabao Dingye Technology Co., Ltd., the crude iron stairs led us to the front of three "big guys". Glassware and metal pipes were connected with each other, and traces of tape fixation could be seen at individual joints.

"These three devices took two years, and it took about 10 million yuan to mature." Touching a sunken pipeline on the equipment, Chen Caihu, general manager of Mianyang Huabao Dingye Technology Co., Ltd., was quite emotional.

In 2016, at a technical achievement conference, Chen Caihu learned that a silicone material technology of China Academy of Engineering Physics was looking for a transferee. After paying 7 million yuan for the technology, it took him three years to get through the road of industrialization and finally made a profit in June 2019.

When a technology moves from laboratory to industrialization, it is necessary not only to optimize the production process to reduce costs and stabilize product quality, but also to identify the market and develop products around market demand. To this end, Chen Caihu set up a research and development team and solved the production process problem in two years. In order to find the market, he conducted a market survey for one year before purchasing the technology, and then conducted product verification with downstream enterprises for three years. "It is to convince the other party that your product quality is excellent and reliable."

Take the LED packaging adhesive market as an example. Compared with the epoxy resin in 100 yuan, the luminous flux of silicone, which is several thousand yuan per kilogram, is larger, which can make the LED brighter. However, processing enterprises dare not rashly adopt new suppliers, which requires product verification, and it takes one year to do it once.

"I feel very lucky, the technology is very good, mass production can be achieved, and the market has given us an opportunity to break the monopoly of foreign brands, but the intervening years are really not easy." Chen Caihu said.

Simplify complexity

Customize the "knife method" and deepen the public production service, so that big countries can also "dance"

The ground part is as high as 27 meters and weighs about 22,000 tons, of which 68 are single parts exceeding 70 tons-the world’s largest 80,000-ton die forging press, which is a well-deserved "big country heavyweight".

This press makes the metal material flow in the die under strong pressure, refines the internal grains, and realizes the overall precision forming of large die forgings. It is mainly used in aerospace, nuclear energy, petrochemical industry, shipbuilding, power and other industrial fields. "For example, in the past, an aviation component needed to weld two pieces. With a large die forging press, it can be formed at one time, making the product more integrated, precise and lightweight." Xie Jing, deputy general manager of China Erzhong Wanhang Company, said.

If the 80,000-ton die forging press is compared to a "treasure knife", it is necessary to rely on Deyang’s strong industrial production service ability to tailor the "knife method" for forging different workpieces.

For example, in order to ensure the accuracy of a C919 product, sichuan engineering technical college took the lead in designing a set of strengthening scheme for high-temperature wear-resistant materials. Through small-scale tests, it took half a year to improve the wear resistance of a set of molds, ensuring the precision control of the product and solving the bottleneck problem for the mass production of C919 products.

At present, Sichuan Institute of Engineering and Technology has three provincial engineering laboratories, which can help similar high-tech equipment and instruments in Chengde Mian to give full play to their hidden value.

In the Robot Application Technology Engineering Laboratory of Sichuan Equipment Manufacturing Industry, the high roof is enough for the drone to take off and take aerial photos inside. The factory building is large, and the processing objects are also large. A dark "round cover" with a diameter of about 3 meters is placed in a bright and modern laboratory, and a large piece of newspaper on it has been polished to reveal the background color.

This is a valve cover used in nuclear power field. When it is cast, it has a layer of black substance on its surface, which needs to be cleaned and polished with a grinding wheel. In the past, these jobs required workers to work at high temperatures. The task undertaken by this laboratory is to replace it with robots. "This is actually very difficult. Industrial robots are suitable for simple and repetitive work, and this work requires robots to identify and plan their own paths." Hu Minghua, head of the laboratory, said.

A yellow industrial robot stood by, with many "weapons and equipment" hanging on it. "This one is equivalent to the robot’s eyes, and this computer is the head." In Hu Minghua’s view, robots, lathes and even 80,000-ton die forging presses are all basic platforms. To use the platform well, a special team is needed to design and develop application schemes. "Our team is entrusted by the enterprise to tailor the solution for it, so that the effectiveness of the platform can be fully exerted." Hu Minghua said.

　　Mobile display of the latest Russian T-90C main battle tank wearing a new camouflage system [data photo]

　　Russian Deputy Defense Minister makarov told Russian media on the 22nd that Russia is testing a tank with excellent performance, and the test work will end next year, and the army will be produced and equipped in 2009.

　　Ten years ahead of the west

　　Makarov said that the combat performance of this new type of tank is better than that of all types of tanks at home and abroad, and its running device, driving device, fire control system, weapon, target identification and reconnaissance system are all new.

　　The analysis pointed out that Russia’s new tank is most likely the T-95 speculated by the outside world. As early as the mid-1980s, the former Soviet Union started the development plan of the fourth-generation main battle tank T-95, but it stopped for various reasons. This new tank weighs 50 tons, and its length and width are basically the same as those of T-72 and T-80. It has absorbed many advantages of active tanks and given more special properties, which has far exceeded the new main battle tank being developed in the United States. It is said that it will take at least 10 years for the west to catch up.

　　The fourth generation of new modeling

　　According to the data, the firepower is one of the biggest advantages of the T-95. In addition to the comprehensive strike fire system, its gun-launched missiles can penetrate 1200 mm thick armor at a long distance, and the hit rate is guaranteed to be above 80%. The T-95 has a maximum off-road speed of 85km/h and is equipped with an intelligent suspension device, which doubles the off-road speed and improves the stability by 10 times.

　　In terms of protective measures, T-95 adopts all-titanium alloy modular armor with high strength and good toughness, so that the resistance can reach or exceed 1500 mm thick steel plate. Different from the previous Russian tanks, the T-95 broke the tradition and adopted the unmanned turret design, and its automation degree was obviously improved. The tank crew will be reduced to two, namely the captain and the driver (and mechanic). It pays attention to the ergonomic design, the cockpit is completely separated from the combat cabin with armor plates, the chair is comfortable, the cabin activity space is more spacious than other tanks, and the fatigue factor caused by narrow space is reduced.

　　In addition, the T-95 is equipped with the most modern radio equipment. With its low profile, powerful artillery, advanced protection and anti-dust measures, T-95 can have an advantage in the confrontation with any modern tank.

　　Russia stepped up its armament.

　　Russian President Vladimir Putin said in his State of the Union address in April this year that Russia must continue to strengthen its armed forces, and Russia has begun to implement the national weapons and equipment plan for 2007-2015, most of which should be used to purchase new weapons and military technology and equipment in bulk. According to Russian media reports, Russia’s defense budget in 2007 was 822 billion rubles (US$ 1 is about 25 rubles), which means that Russia urgently needs weapons and equipment, most of which will be used to update naval weapons and equipment, at least 50% of which will be used for submarine forces.

"Daily Car News", here is the latest car news of the day, please continue to pay attention to "Know the Way of Cars".

　　Beijing, January 1 (Xinhua) According to Bloomberg News, Tesla and Twitter CEO Musk became the first person in history to lose $200 billion due to the sharp drop in Tesla’s share price.

　　According to the Bloomberg Billionaires Index, after Tesla’s share price plummeted in recent weeks, the 51-year-old Musk’s wealth plummeted to $137 billion. Musk’s net worth peaked on November 4, 2021, when it was estimated to be $340 billion, and has been shrinking since then. In early December 2022, bernard arnault, the chairman of Louis Vuitton Group, briefly surpassed Musk to become the richest man in the world.

　　According to reports, Tesla’s share price fell sharply in 2022, falling by 65% for the whole year. Musk also sold a lot of Tesla shares in 2022 to help pay for the $44 billion he spent on acquiring Twitter.

　　The decline in Tesla’s share price is particularly related to investors’ concerns that Musk will pay more attention to Twitter than electric vehicle production.

　　Musk refuted everyone’s concerns about Tesla and repeatedly criticized the Fed for raising interest rates at the fastest rate in a generation on Twitter.

　　"Tesla’s execution is better than ever!" Musk tweeted on December 16, 2022. "We can’t control the Fed. That’s the real problem."

　　Musk had previously borrowed heavily from Tesla shares, but recently warned that it was dangerous to borrow money in a panic market.

Recently, Mercedes-Benz officially announced that Beijing Mercedes-Benz domestic EQE model will be officially launched on August 24th. Beijing Benz EQE is also the first joint venture brand luxury medium and large pure electric car officially launched in China. It is reported that the new car has been pre-sold: the pre-sale price is 530,000 yuan, 550,000 yuan and 590,000 yuan respectively. In terms of positioning, it is also equivalent to the size of Mercedes-Benz E-Class long wheelbase. In terms of power, it will be equipped with a permanent magnet synchronous motor with a maximum power of 215kW, and the maximum cruising range of CLTC will reach 752km.

EVA platform to create the appearance of "small EQS"?

As the first pure electric car produced in China based on EVA platform, firstly, in terms of appearance, EQE inherits the design style of EQS, the fully enclosed front grille is integrated with the headlights on both sides, and the headlights are irregularly designed, which has good recognition. In addition, in order to please young consumers, the front enclosure of the new car has adopted a sharper design, and the three-stage cooling opening shape is also in line with the aesthetic feeling of young people for sports.

On the side of the car body, the consistent elegance and stretch of Mercedes-Benz models are undoubtedly revealed at this EQE. Without the "bondage" of gasoline engines, the whole side of the new car is more like a "spaceship", and in terms of body size, the length, width and height of the new car are 4969mm/1906mm/1509mm, respectively, and the wheelbase is 3120 mm. Except for the length of the car, other dimensions are ahead of the E-class long wheelbase, but the design of the sliding back may sacrifice part of the overhead space in the car.

The penetrating taillights, "duckling tail" and rear bumper are decorated with diffusers instead of the visual effect of exhaust, which makes the whole tail more integrated and echoes the design of the front.

The interior looks like the cash S-class. Continue to follow the "nightclub style"?

As one of the "interior killers", Mercedes-Benz has always been very good at rendering the atmosphere inside the car and showing luxury. It is also reflected in this EQE: large-area wood grain or special texture panel decoration, embracing center console surface, through air conditioning outlet, blue and white interior color matching symbolizing new energy, exquisite door panel decoration and other details are not absent, even "exactly the same" as the new S-class.

However, it is a pity that none of the three models made in China this time have Hyperscreen three-screen linkage system, and at present, they do not support optional installation, which may be because they hope to control the cost and open the gap with the imported version EQS, while the new car will be equipped with a 12.3-inch full LCD instrument panel and a 12.8-inch vertical suspended central control panel. Even so, the overall interior is not inferior in terms of luxury and technology.

In addition, according to the previously published interior official map, the domestic EQE will also inherit the "nightclub style" of other family models in the atmosphere light, and according to speculation, this atmosphere light will not only surround the central control, the body and the door handle, but even be arranged in the seat part.

The rear drive single motor has a battery life of 752km.

The three electric systems of Mercedes-Benz EQE are all produced by Beijing Benz. The first three 350 models are single-motor rear-drive versions, and are equipped with permanent magnet synchronous motors with a maximum power of 215kW and a peak torque of 530 N m. The capacity of NCM811 battery pack is 96.1kWh, and the officially announced maximum cruising range of CLTC can reach 752km.

Write at the end:

For the new energy market, domestic models have already been laid out, and the performance of previous EQA, EQC and other models is flat. Whether the upcoming Beijing Benz EQE can break through the sales of Mercedes-Benz in the new energy market by relying on its excellent interior atmosphere, excellent chassis adjustment and brand blessing. We will wait and see how EQE will perform in the future.

　　Xinhua News Agency, Beijing, September 30-The House of Representatives, controlled by Republicans in the United States, held a hearing on the 28th to open an impeachment investigation against Democratic President joseph robinette.

　　On the same day, Biden "fired at" former Republican President Donald Trump at the event, calling the latter and his fans "extremists" and a threat to American democracy.

　　Open "play"

　　The House Oversight and Accountability Committee held the first hearing of impeachment investigation on 28th, aiming at finally proving Biden’s illegal behavior in overseas business activities engaged by his second son Hunter. The theme of the first hearing is the legal basis of impeachment investigation, and the witnesses summoned are legal and criminal investigation experts.

　　James Comer, the chairman of the committee and a Republican, said at the hearing that Biden had "abused his power" and "there was a mountain of evidence". Jonathan Terry, a witness summoned by Republicans and a law professor at George Washington University in the United States, said that although the current evidence is enough to launch an impeachment investigation, it is not enough to charge Biden. Michael gerhardt, a witness summoned by Democrats and a law professor at the University of North Carolina, believes that the current evidence is not enough to support the impeachment investigation.

　　With the "preparations" in the early stage of the presidential election in the United States next year, the wrestling between the Republican Party and the Democratic Party has become increasingly fierce. Trump, a popular Republican potential candidate, has been criminally prosecuted four times this year, involving the case of "secret affair", "hush money" and suspected of overthrowing the results of the 2020 presidential election. In the Republican-dominated House of Representatives, Speaker Kevin McCarthy announced on the 12th that he would open an impeachment investigation against Biden on the grounds that Biden was suspected of "abusing power, obstructing justice and corruption".

　　Trump and his supporters say Democrats are launching a political offensive in an attempt to prevent Trump from re-entering the White House. The Democratic Party also accused the Republican Party of playing politics against Biden.

　　A White House spokesman said on the 28th that the hearing that day was "an unfounded stunt" and Biden would still "focus on the priorities of the American people rather than such political games". Jamie Ruskin, a Democrat member of the House Oversight and Accountability Committee, questioned the legitimacy of the Republican impeachment investigation "without a vote in the House of Representatives" and "without conclusive evidence". "If Republicans get a gun with a smoking muzzle, or even a dripping water gun, they will show it today." Ruskin said, "But they have nothing."

　　After the hearing, Comer instructed to collect more records of private and commercial bank accounts of Hunter and Biden’s younger brother James.

　　Democrats also showed a countdown clock at the hearing, accusing Republicans of continuing to push the impeachment investigation despite the dispute over the appropriation bill, which led to another "shutdown" of the US government. Ruskin said that there are only 62 hours left before "closing the door", "but Republicans are impeaching on the basis of lies that have already gone bankrupt."

　　Talk about it.

　　Biden pointed his finger directly at Trump at an event in Arizona on the 28th, saying that the main potential opponent of next year’s US presidential election is the threat of American democracy. Arizona is a so-called "battlefield state" where the democratic and Republican parties compete fiercely.

　　This video shot in Arlington, Virginia, USA on September 29, 2020 shows that then US President Trump (left) and US Democratic presidential candidate Biden participated in the first TV debate of the 2020 US presidential candidate in Cleveland, Ohio. Xinhua News Agency reporter Liu Jie photo

　　The day’s activity was to celebrate the opening of the library to commemorate former Republican Senator John McCain who died of illness in 2018. Mccain was Trump’s sworn enemy.

　　According to Agence France-Presse, during Trump’s previous criminal prosecution, Biden has always avoided commenting on Trump’s lawsuit, but now he no longer evades and directly attacks Trump personally.

　　Biden said, "Some dangerous situations are emerging in the United States." "Trump said that the Constitution gives him ‘ The right to do whatever you want ’ … … (He said this) with the heart of revenge. "

　　Biden described Trump and his die-hard supporters as "extremists who have no common democratic beliefs with us".

　　Trump, who mentioned media reports, once called American soldiers captured and killed in the war "fools and losers". Biden asked whether his eldest sons bo Biden and McCain were also "fools and losers". Both of them served in the army, and McCain was captured in the Vietnam War.

　　In response to Biden’s remarks, Trump’s campaign team responded that "the ultra-left Democrats headed by Biden are the biggest threat to democracy in the history of the United States." (Hui Xiaoshuang)

　　"This bearing requirements are high. Look at the drawings, the design error here is only allowed to be 0.02 mm, so pay special attention. " At 8: 30 in the morning, Ma Jianjun exchanged technical research points with his disciples. Ma Jianjun is a key member of the machine tool performance laboratory of Baoji Machine Tool Group Co., Ltd. in Baoji High-tech Zone, Shaanxi Province. He has participated in the development and trial production of key new products and more than 30 major national special tasks, achieved more than 20 technological innovations, and successfully completed more than 50 major special machine tool commissioning, debugging and after-sales service tasks.

　　Ma Jianjun graduated from Baoji Technical School. In July 1994, he came to the machining workshop of Baoji Machine Tool Factory and became an ordinary lathe operator. With only a degree of Chinese technical education, he suddenly felt unprecedented pressure in the face of high-precision processing equipment.

　　"I just want to learn the technology well, study with the master during the day and go home for self-study at night." Technology, programming, electricity and cutting tools are the keys to the machining technology of CNC machine tools. Ma Jianjun uses his good foundation in turning technology to learn by doing and learn by doing. When he meets problems he doesn’t understand, he asks the master and inspectors, and takes time to check the information and take notes at night. After a few years, he wrote down more than 10 study notes and applied them to well-known CNC systems freely. Ma Jianjun once won the title of "Excellent Player" in the "Qinchuan Cup" first skill competition for employees of state-owned enterprises in Shaanxi Province, and participated in many national, provincial and municipal vocational skills competitions as a referee or technical director. Since 2010, he has been awarded the "lathe technology demonstration post" by the group company, and in 2015, he became the backbone member of Tian Haorong’s national skill master (model worker innovation) studio.

　　In 2012, during his four-month equipment technical service for a company in Wuxi, he overcame difficulties, fulfilled his duties dutifully, and successfully completed the assignment abroad. In recent years, the company has successively ordered more than 100 machine tools from the company.

　　In 2015, the key contract delivery of a company in Chongqing was just around the corner. Due to the tight time and high technical requirements, the company leaders are very anxious. Ma Jianjun took the initiative to take this "hard bone." He "nailed" the user’s trial production site for more than ten hours in a row, worked overtime to carefully study and ponder over each equipment, compiled the processing route program diagram, made corresponding fixtures and configured appropriate tools, and finally completed the dispatching and commissioning tasks of 14 CNC machine tools.

　　Since 2014, Ma Jianjun has participated in a number of major national R&D and trial-production tasks for high-end CNC machine tools. Especially during the national major special research project and working in the machine tool performance laboratory, he was processing BTGS12 spindle, pull rod and ON— When processing parts with high precision coefficient and small tolerance range, such as rollers and D-rings in 3VII, with superb business skills, the processed parts exceeded the precision required by the drawing process and successfully completed the production task.

　　In addition, Ma Jianjun cooperated with the research group to overcome a number of technical difficulties and broke through a large number of key processing technologies of CNC machine tools. In undertaking the R&D and production of BM63150C precision CNC lathe project, he boldly innovated, optimized the oil return structure at the back end of the machine tool spindle, and eliminated the weak links that affected the reliability of the machine tool; Through numerous groping, adjusting cutting parameters and workpiece clamping methods, the hard turning process test was finally completed, and the product won the "Chun Yan Prize" in cmtba. He also successfully solved the key new product BMC— The technical problem of machining the parts of the clamping sleeve in the center of 500TV five-axis compound milling machine makes the company’s first five-axis CNC machine tool enter the high-end market.

　　Ma Jianjun has more than two suggestions for minor reform and process improvement every year, and has completed more than 30 key technical projects with studio members. In 2016, his studio passed the acceptance of the national skill master studio, and won the award of "All-China Workers’ Innovation Studio Key Project Fund". Advanced practices and experiences were promoted and exchanged in Shaanxi Province, realizing the transition from ordinary operating workers to knowledge workers, and then growing into expert talents in the new era.
