  On February 25th, the largest professional and technical competition in the history of the North Sea Fleet came to an end after three days of fierce competition. The officers and men of the fleet stationed on the long coastline of the northern part of the motherland shared the grand occasion of the awards and commendation meeting through various video calls. The "top trainers" and "technical experts" who won 210 individual medals and 52 team medals in 16 majors and 85 events went to their respective positions with great pride.


  The Jingwu arena is fiercely competitive, and the drums are inspiring. There are many "highlights" and frequent "highlights" on the competition field.


  "Ending" becomes "Opening"


  In previous years, military competitions were generally arranged in the second half of the year. As the "ending" project of annual training, it is more to play the functions of "acceptance" and "evaluation".


  However, as soon as the training of the North Sea Fleet started this year, it began to compete with unprecedented professional skills. What is the intention of "ending" to "opening"? During the interview, the reporter learned that the preparation for this competition has actually been fully rolled out in the fleet forces since March last year.


  It is the original intention of the fleet leaders to set this grand contest at the beginning of the year to lead the fine martial arts and create an atmosphere of on-the-job training. Liu Shusen, deputy captain of a landing ship who won the title of captain’s professional competition, told the reporter that from the professional and technical competitions held at different levels of ships, brigades and detachments, he was "killed" by the fleet all the way.


  "Soldiers are the most glorious warrior. The contest shows strength and heroic spirit, and no one in each unit will admit defeat. " A destroyer detachment organized troops to hold full-staff, full-post, full-specialty and full-system professional and technical competitions, and conducted intensive training for the contestants by means of centralized teaching, classified guidance and on-site observation, and eliminated them in turn and selected them at different levels.


  With the competition as the traction, this fleet has set off a vigorous training upsurge from the grass-roots ship company to the divisions and regiments, from ordinary soldiers to leading cadres, from front-line personnel to security forces. Tong Haiqing, political commissar of a speedboat detachment, said: The competition has promoted the enthusiasm of officers and men for training. The officers and men on the small landing craft know that it is difficult to jump into the ring of the fleet, and they are also gearing up for their posts; Some "unique" majors are too few to compete, and they also strongly demand to set up competition projects for them.


  It’s better than not knowing, and it’s better than knowing. Chen Guiqiu, deputy director of the Military Training Department of the Fleet, vividly compared: This is a "general survey" of the combat effectiveness of the troops. Although it is impossible for all officers and men to become top trainers, they can find out which fields and majors have talents by conducting competitions at different levels. Which ship, which battle position lacks backbone, and which projects are still weak. This is undoubtedly conducive to enhancing the pertinence of training guidance, reinforcing the strong and reinforcing the weak, and promoting the whole.


  This competition adapts to the development of equipment and technical progress, tests the latest level of professional technology, sets a new benchmark for military training, and lifts the professional technical training of the fleet to a higher starting point.


  "Watching the war" becomes "participating in the war"


  "Veterans fight and recruits watch." This seems to have become a fixed trend in the previous military competitions, and the "technical skills" that dominate the ring are mostly "old faces". However, this time, senior non-commissioned officers only accounted for a small number of contestants, and more new forces such as conscripts and junior non-commissioned officers bravely appeared.


  Chen Lixing, a new generation pilot of Hainan Airlines who just graduated last year, competed on the same stage with Zuo Wenmeng, a pilot of the deputy division for 30 years. Each of them performed their unique skills and competed fiercely for two hours, making it difficult to win or lose.


  On the one hand, the old horse is full of courage, and on the other hand, the newborn calf dares to fight. The reporter saw in the competition field that in the professional competition of guns, Du Haitao, a superior soldier who had just joined the army for one year, fought fiercely with He Maobin, a four-level sergeant with rich experience; Wang Mian, a first-class petty officer, competed with Zhang Guochao, a third-class petty officer, and Zhang Chunying, a major female officer, which became the most eye-catching attraction on the field.


  In recent years, the composition of soldiers has changed significantly, and many college students have joined the army. Some recruits have undergraduate and junior college degrees, and they are highly savvy, receptive and quick to master new technologies. Coupled with the changes in the military training environment in recent years, weapons are frequently used in practical activities such as long-distance training and major exercises, and the training intensity is high. Officers and men are also greatly trained in their posts, and the growth cycle of professional and technical experts is obviously shortened.


  It’s no better than not knowing, and it’s a "shock"! This new force in military training has activated the training ground. Song Wei, a 315 submarine rudder technician and a fifth-class noncommissioned officer who won the first prize of outstanding noncommissioned officers in the whole army, said frankly when participating in the professional competition of submarine signals: "The strength of new players can not be underestimated, forcing us old backbones not to slack off!"


  In the past, post training focused on training "soldiers", and this time the professional competition cadres no longer watched the excitement. The reporter opened the competition order book and saw that the contestants included ship captains, pilots, staff officers and technical cadres. The most interesting thing is the number of ship captains and flight group leaders. They have heavy burdens and busy work, but they also attach importance to laying a solid foundation like soldiers and players, and put pressure on themselves through competitions.


  Liu Shusen, the deputy captain of a landing ship, took the time to learn the knowledge of command and safety theory, exercised command skills in practical tasks, and achieved the combination of learning and application. In this competition, he won the first place in the professional competition of the captain of the ship, showing a solid commander’s foundation.


  "Supporting role" becomes "protagonist"


  At the scene of the equipment professional competition, the reporter saw that the "grinding technology" that had been "forgotten" for many years reappeared in the competition ring. Twenty-two contestants "copied" the same model of spare parts on the mechanical operating platform, and raced against time to process the grinding parts. Zhang Dingxi, a five-level sergeant of a destroyer detachment, told the reporter: "I have participated in professional competitions organized by higher authorities many times, and this project has not been compared for many years."


  The highlight of this North Sea Fleet competition is "professional technology", which covers all fields and covers all majors. From the combat use of missiles, torpedoes and artillery to the practical operation of electromechanical, communication and chemical defense; From the supply guarantee of diet, medical care and oil, to the troubleshooting and emergency repair of equipment, equipment and facilities, not only the "main" major has made a strong appearance, but also the "marginal" category has made a new appearance.


  The purpose of such a comprehensive and extensive competition project is to fully cover the usual basic training. Professional technology is the basis of combat effectiveness, and no link in the combat effectiveness chain can be missing. Some "marginalized" professional technologies also have the opportunity to exert their fists. Yu Yongfeng, a second-class noncommissioned officer in the equipment warehouse of a security base, and five comrades-in-arms are setting up a new class tent at the professional competition site of the infrastructure barracks. They cooperated with each other quickly and achieved the second place in the group.


  According to statistics, there are 26 new events in this competition, whether they are "resurrected" or "newborn", and the project settings will follow the needs of future wars. According to the requirements of the new syllabus, the content of dealing with various security threats and improving the ability to complete diversified military tasks has been added to the competition. The reporter saw at the scene of the competition between the captain of the ship and the pilots that the knowledge points such as "maintaining the safety of important strategic passages at sea" and "maritime international law" all entered the test paper of the theoretical competition.


  Tournament not only highlights the important position of basic training, but also makes officers and men fighting in different positions firmly believe that professional skills are only "high and low" and have no status "high and low". They broke the traditional concept of "leading role" and "supporting role" and re-defined their roles: all professional and technical posts related to combat effectiveness should be pursued by you, actively trained, laid a solid foundation and used well, so as to promote the overall combat capability of the fleet to jump!

The domestic large aircraft C919 made its first flight today, and the overall localization rate reached over 50%.

  Guangming. com May 5 th (Reporter Zhan Wei)This afternoon, the domestic large passenger plane C919 will make its first flight at Shanghai Pudong International Airport. From 1970, when the project was initiated to develop "Yun 10", to 2007, it was decided to carry out the reform of aviation industry system, and the project was initiated to develop C919. The civil aviation industry in China experienced a difficult and bumpy development course. The moment of the first flight of C919 bears the struggles and dreams of several generations of China civil aircraft people. Let us have a more comprehensive understanding of C919.

The domestic large aircraft C919 made its first flight today, and the overall localization rate reached over 50%.

  On May 4th, in the hangar of Zhuqiao Base of China Commercial Aircraft Corporation Flight Test Center, the staff inspected and maintained the domestic large passenger plane C919. Xinhua news agency  

  Why is it named C919?

  According to Comac China, the full name of "C919" is "COMAC919".

  Among them, "COMAC" is the abbreviation of the English name of Commercial Aircraft Corporation of CHINA Ltd, which developed C919. The "C" in the abbreviation is the first letter of "COMAC" and the first letter of China’s English name "China".

  The first 9 means "everlasting", and the last two 19 means that the maximum capacity of C919 passenger plane is 190 passengers.

  Previously, the internationally renowned aircraft manufacturers were Air Bus and Boeing, and from A to B to C, they just lined up.

  What kind of research and development process has C919 experienced?

  According to official website of China Commercial Aircraft Corporation, C919 is a large jet civil aircraft developed by China in accordance with international civil aviation regulations and with independent intellectual property rights, with 158-174 seats and a range of 4,075-5,555 kilometers.

  It took 10 years from 2007, when the major scientific and technological special project of large aircraft development was formally approved, to 2015, when the first aircraft of C919 was assembled and rolled off the assembly line in China Commercial Aircraft Assembly and Manufacturing Center, and today, the domestic large aircraft will soon fly from blueprint to flying in the blue sky for the first time.

  During this period, researchers have planned 102 key technical problems for advanced pneumatic layout, structural materials and airborne systems. In preparation for the first flight, the C919 has completed 118 test projects and experienced 21 taxiing tests including low, medium and high taxiing, and passed the expert technical review in March 2017 and the release review in April.

  Why is the first flight important?

  The first flight of an airplane refers to the first flight of a newly manufactured airplane from the ground. Every plane has its first flight, but the first flight of a new model has its special significance. It is not only an important link in a series of work chains, such as changing ideas into drawings, drawings into objects, and objects can fly, but also an important milestone in the turning point of new models from static to moving and the birth of new models.

  According to the relevant person in charge of Comac, as long as the plane begins to taxi and leave the ground during the first flight, the most basic system functions will be preliminarily assessed. The test pilot will comment on the aircraft’s handling stability, take-off and landing performance, power plant and driving equipment for the first time. Generally, the first flight time of light aircraft does not exceed 30 to 40 minutes, and that of large aircraft is 1 to 2 hours. Generally, the first flight chooses a good weather, with visibility not less than 5 to 7km, and no low clouds and crosswinds. The flight weight of the first flight plane should be reduced as much as possible, so as to minimize the take-off speed from the ground and shorten the take-off taxi distance, thus improving driving conditions.

  How to fly on the first flight?

  The maximum altitude of the first flight of C919 is 10,000 feet, the maximum speed is 170 knots, and there are 15 test points. The whole process is divided into five stages, namely, ground inspection stage, climbing stage, level flight stage, simulated approach, landing and go-around stage and landing stage. Traditionally, the C919 did not retract the landing gear during the first flight, and kept the flaps down.

  In addition, when the C919 makes its first flight, a second plane will accompany it. The task of companion flight is to observe the first flight plane in real time in the air, record flight data, take photos and videos, and make every effort to ensure the safety of the plane during its first flight. In case of any problems, the crew of the accompanying plane will immediately warn the crew of the first flight, report to the ground control personnel and guide the first flight to land safely. In addition, the accompanying aircraft will also monitor the air environment of the first flight to ensure that no other aircraft will break into the flight route of the first flight and put an end to any hidden dangers of stealing secrets.

  How about the localization of C919?

  Zhou Guirong, deputy chief designer of C919 large passenger aircraft, said that at present, the overall localization rate of C919 aircraft can reach more than 50%, including domestic enterprises and joint ventures at home and abroad. The safety requirements of aviation products are very high. The development of the whole localization, whether at home or abroad, is in accordance with the same set of international standards and methods, and the trial is also in strict accordance with international standards and norms.

  China Commercial Aircraft Corporation insists on "main manufacturer — Supplier "development mode, maximize the gathering and utilization of domestic and foreign resources, and build a" life community "of the civil aircraft industry. There are 22 provinces and cities, more than 200 enterprises and 36 colleges and universities involved in the development of C919 large passenger aircraft. Sixteen material manufacturers and 54 standard parts manufacturers including Baosteel have become suppliers or potential suppliers of large passenger aircraft projects. China Comac also signed strategic cooperation agreements with six central enterprises, including aviation industry corporation of china, and established strategic cooperation relations with seven major domestic banks.

  In the development of C919 large passenger plane, researchers have planned 102 key technical problems, including integrated design of aircraft engine, control law design of fly-by-wire flight control system, active control technology, etc., aiming at advanced aerodynamic layout, structural materials and airborne system.

  Take most of the front fuselage of C919 as an example, which includes the front passenger cabin, the front cargo cabin and the recirculation fan cabin, and contains more than 1,600 parts, involving nearly 2,000 tooling. This section adopts the third generation aluminum alloy — — Al-Li alloy material, which is the first time in domestic civil aircraft application. Al-Li alloy material is considered as the most ideal material for aerospace at present. China Commercial Aircraft Corporation and AVIC Hongdu Aviation, a joint supplier, have completed 20 batches of material performance data tests under stable process conditions through the tests of 2,500 test pieces in recent three years. Around the establishment of material fatigue rating (DFR) data system, DFR fatigue tests of typical structural details in different processing and manufacturing States were carried out, with more than 3,000 test pieces. The processing technology of Al-Li alloy structure, such as chemical milling, machining, hole-making, hot-pressing subsidence, mirror milling and heat table treatment, has been fully verified. Through tackling key problems, the model material specification system and performance data system for design are gradually established.

  How did the C919 market react?

  Focusing on the most mainstream air transport market, C919 is a trunk aircraft developed in full compliance with international mainstream airworthiness standards and international mainstream market operation standards. At present, C919 large passenger aircraft has 23 domestic and foreign customers, including China International Airlines, with a total order of 570 aircraft, including international customers such as GECAS.

  What is the significance of C919 to China?

  Large aircraft is a high integration of modern high technology and is called "the jewel in the industrial crown". C919 means that China’s civil aviation will no longer rely on foreign imports, and China’s aircraft manufacturing has truly embarked on a road of independent development.

  Driven by the C919 large passenger aircraft project, a technological innovation system of civil aircraft has been formed, which is based on China Commercial Aircraft Corporation, market-oriented and combined with Industry-University-Research. China Commercial Aircraft Corporation (Comac) has built a technical responsibility system around the realization process of civil aircraft products and the technical requirements of full-life cycle service, and planned to promote the technical system construction with standards and specifications as the main carrier. Through scientific research and innovation research, model technology research and other ways, it has continuously formed new civil aircraft technical achievements and supplemented and improved the civil aircraft technical system.

  Millions of fine parts, covering high-end manufacturing of almost all industrial categories — — Domestic large aircraft soaring in the blue sky will undoubtedly drive China’s manufacturing industry to the "smile curve".

  From the upstream, the development of large passenger aircraft can drive the group breakthrough of key technologies in new materials, modern manufacturing, advanced power, electronic information, automatic control, computers and other fields, and can promote the development of many high-tech industries, with a technology diffusion rate as high as 60%. The technological upgrading of its industry will inevitably require great progress in many basic disciplines, including fluid mechanics, solid mechanics, computational mathematics, thermophysics, chemistry, information science, environmental science and so on. From the downstream, the commercial operation of large civil aircraft has a great impact on civil aviation transportation, aviation maintenance, aviation finance, tourism, logistics and other industries.

  For China, the breakthrough of large-scale aircraft technology will not only promote the development of a number of new industries, but also force the upgrading of China’s industrial standards by continuously expanding the industrial chain and introducing airworthiness certification in China, thus promoting the overall improvement of China’s industrial manufacturing capacity and level. Some experts said that in the 21st century, only a breakthrough in high-end large-scale equipment manufacturing such as large aircraft can support the foundation of China as an industrial power. At the same time, it also contributes to the transformation of China from a "manufacturing power" to a "manufacturing power".

Homework can’t be solved by search software? This phenomenon should be managed.

  With the search software, my mother no longer has to worry about my study?

  But in reality, there is such a problem. Students who make perfect exercise papers don’t score high in the exam. Usually, when you encounter homework problems, open the network search software to check, and the direct answer will come out, and the exercise paper will be completed well and quickly; But in the examination room, there is no "blessing" of the search software, and the same problem-solving ideas are full of mistakes.

  On the eve of the Eighth Young Pioneers Congress in Shanghai, many young pioneers, including Maree Lau from Shanghai No.54 Middle School and Tang Ying from Tangwai Middle School in Fengxian District, paid attention to this phenomenon and made investigations. At the same time, they submitted relevant proposals, suggesting that the number of times of searching questions by using search software should be limited, and the software should provide ideas for solving problems instead of giving answers.

  The exercise paper is perfect, but I guess it even in the exam.

  Maree Lau, a student from Shanghai No.54 Middle School, was very impressed by an exercise paper on the calculation of mathematical real numbers, and the steps of each calculation problem were impeccable. But in the math exam, the student who made the perfect exercise paper didn’t score high.

  Exploring the reasons behind it, Maree Lau found that many students around him did not think about how to solve the problem by themselves first, but habitually turned on the network search software to check the answer, and easily made a perfect score assignment through the function of tapping the question in seconds by some software. "Solving problems without thinking is useless for learning. They often expose many problems in exams." Maree Lau said.

  Tang Ying, a student from Tangwai Middle School in Fengxian District, also found that some students around her used the online search App and conducted "autonomous learning". The completion of homework achieved acceleration, but the learning attitude and independent thinking ability were greatly affected. I could only guess in the exam, and the error rate soared.

  How many students have tried to solve problems with search software? Maree Lau and Tang Ying conducted research in their schools respectively.

  The former found that the survey showed that 85% of the students would use the search software when they encountered problems, and more than 70% of the students chose "Yes" when answering "Do you have any excellent homework by software around you?".

  The latter found that more than 90% of the team members are familiar with homework search software or channels such as homework help and Little Ape Search, among which more than 50% of the team members have used this method for "autonomous learning" or homework completion, including those with excellent academic performance.

  Tang Ying said frankly: "Some of these players use the software to find ideas for solving problems and read excellent articles, while others copy the answers directly and just want to finish their homework as soon as possible."

  Maree Lau also noticed the feedback that "the software sometimes gives wrong answers". To this end, she used the software to carry out experiments and found that some questions will have correct answers and two or three wrong answers at the same time. "It is a difficult problem that can’t be solved, and then giving the wrong answer will not only solve the problem, but also mislead the questioner."

  Limit the number of times of use and only give ideas for solving problems.

  At Tangwai Middle School in Fengxian District, Gu Bei, a team counselor, also organized an in-depth discussion. As a result, I heard the voices from the players.

  "They said that they sometimes want to ask their parents about the questions they can’t do, but the other party is always busy looking at the mobile phone and letting the children go online to check the answers. Sometimes the other party will also look at the problems encountered by the children, but it turns out that they won’t do it either, and finally they will check it online." Gu Wei said.

  As a teacher, Gu Bei does not advocate the use of online search software, but she also noticed that "there is a demand behind this problem". The key is to let students understand what the "initial intention" of using software is, "is it to help them learn the problem-solving ideas or just to be lazy and have fun?"

  Maree Lau also said that when the search software becomes a "helper" to complete homework, students will be overly dependent and lose their independent thinking ability.

  Maree Lau suggested that the search software can be used as a platform to assist students in learning, but it is necessary to "limit" the number of questions per day. "I think it is better to limit the number of questions per day to less than 10 times, and then refer to it if it is not."

  In addition, she thinks it’s best to use the software in real-name registration system. A student can only apply for one number, and the software should also check the correctness of the answers to the questions regularly.

  Jiang Chenyue, a small representative from Shangmei Middle School in Qingpu District, Shanghai, suggested that the right to use the software can be "restricted". "For example, we don’t give the answers directly to the questions we check, but give the ideas for solving the problems, so that we can use our brains to solve them ourselves."

  Tang Ying suggested that if the team members want to reduce the use of search software, the subject teachers in the school can analyze and record the problems and upload them to the campus APP, so as to provide problem-solving ideas for the team members’ learning. By learning videos and punching in points, the team members can be encouraged to see more, think more and compare more.

  Tang Ying also suggested that a "study group" can be set up in the squadron, and a study group system can be set up to study together during recess and after school. "Parents should never save trouble, just throw us to mobile phones and computers, and you can watch online problem-solving ideas with us and solve problems together."

Water turns into ice, reflecting sunlight.

Recently, affected by the continuous cold air, many places in China have ushered in a wide range of snowfall. On the morning of February 25th, in the Evergreen Flower Community of Dongxihu Lake, the original accumulated water gradually froze in the cold, with different shapes, reflecting the rising sun.
With the continuous drop of temperature, the accumulated water in the community gradually freezes. Especially in some low-lying areas, the accumulated water forms a thin ice layer, which forms a beautiful picture with the surrounding buildings and trees under the sunlight.
While the continuous snowfall has brought beautiful scenery to the residents of the community, everyone should also pay attention to the weather changes and their own safety.(Changjiang Daily reporter Liu Bin photo report)

Reform of professional title system Foreign language examination is no longer a hard requirement for assessment.

  Core reading

  In January this year, the Central Office and the State Council issued the Opinions on Deepening the Reform of the Professional Title System, which continued to promote the reform of the professional title system and proposed that there should be no unified requirements for the professional title foreign language examination, which attracted widespread attention. Professional title evaluation needs to pass the professional title foreign language examination, which has been implemented for many years. Why not make a unified requirement? How is the progress of all localities in canceling this rigid requirement? Does it mean that foreign languages are not important to evaluate professional titles?

  It is out of date to optimize the structure and level of the talent team, and "one size fits all"

  At the end of last year, Li Hua (a pseudonym), an old teacher in a research institute in Shandong, was finally awarded a senior title.

  "Don’t begin to understand" is Li Hua’s evaluation of personal foreign language learning. As a professional backbone of studying the history of China, he has a good knowledge of ancient Chinese characters, but he is not so "smart" in learning English. Every year, he buys the latest reference books, spends a lot of time learning English and even takes part in training. But after more than ten years of examination, I just failed to pass the foreign language title. In July 2016, the Shandong Provincial Department of Human Resources and Social Security issued a notice, which no longer made uniform and rigid requirements for the foreign language test for professional titles. "This has finally passed!" Li Hua said.

  The history of professional titles in foreign languages can be traced back to 1991. The Notice on Strictly Mastering Foreign Language Conditions in the Evaluation and Employment of Professional and Technical Positions issued by the former Ministry of Personnel made it clear that the evaluation and employment of professional and technical positions must strictly master foreign language conditions in accordance with the relevant provisions of the Trial Regulations on Professional and Technical Positions. In 1998, the Notice on the Unified Examination of Foreign Language Grades for Professional and Technical Personnel issued by the former Ministry of Personnel made it clear that professional and technical personnel who hold or promote the corresponding professional and technical titles must obtain a certificate of conformity in the unified examination of foreign languages for corresponding titles, and implement the unified examination of foreign language grades for professional and technical personnel nationwide.

  "It should be said that the professional title foreign language examination system played a historical role at that time. The foreign language examination for professional titles has played an important role in promoting Chinese professional and technical personnel to learn advanced international experience, and promoting Chinese talents to strengthen international exchanges. Therefore, we cannot hold a completely negative attitude towards the foreign language of professional titles. " Yu Jiadong, director of the Technical Department of the Ministry of Human Resources and Social Security, said.

  However, since the reform and opening up more than 30 years ago, English education in schools has been greatly developed, and the structure of talent teams has been more and more optimized. It is out of date for professional title evaluation to make unified requirements for professional title foreign languages. In the interview, the reporter found that some industries have little to do with foreign languages in actual work, but some staff members have spent a lot of energy learning foreign languages in order to evaluate their professional titles; There are also some professional and technical personnel who have obtained other foreign language level certificates before joining the job, and the foreign language examination for professional titles belongs to repeated identification and waste of resources for them; In addition, some industries need certain professional foreign language ability, and the professional title foreign language examination is only an entry level, which can not meet the professional requirements of these positions.

  Zhuan Zhan is engaged in accounting work in a real estate company in Zhengzhou. "Usually, English is used less. Even for H-share listed companies, Hong Kong’s financial statements are bilingual. " In his view, if you want to further integrate with international accounting, the current level of foreign language examination for professional titles is far from enough.

  As early as 2007, the former Ministry of Personnel issued the Notice on Improving the Foreign Language Test for Professional Titles. In order to prevent the foreign language test for professional titles from being "one size fits all", it made specific provisions on certain situations in which it was confirmed that the requirements for foreign language scores could be relaxed or the foreign language test for professional titles could not be taken. In November 2015, the Ministry of Human Resources and Social Security and the National Health and Family Planning Commission jointly issued the "Guiding Opinions on Further Reforming and Improving the Evaluation of Professional Titles of Primary Health Professionals", stipulating that foreign language scores of professional titles of primary health professionals can not be used as reporting conditions.

  At the same time, many places have already had corresponding practices. For example, the "Measures for the Identification of Senior Professional and Technical Qualifications of Special Talents (Trial)" issued by Chongqing proposes that those who meet the requirements, have genuine talents and outstanding abilities and achievements can be evaluated without being restricted by foreign languages and other conditions; In 2007, according to national requirements, Henan Province exempted 13 categories of people who have proved to have high foreign language ability, worked in grass-roots units or engaged in agriculture, forestry and water for a long time, engaged in clinical Chinese medicine with China characteristics and national traditions, and arranged ancient books, and simplified the examination and approval procedures for exemption.

  The abolition of foreign language hard requirements for professional titles has made different progress in various places.

  The Opinions on Deepening the Reform of the Professional Title System issued in January this year clearly stipulates that if there is no uniform requirement for the professional title foreign language examination and it is really necessary to evaluate foreign languages, the employer or the evaluation institution shall independently determine the evaluation conditions; Professional and technical personnel working in hard and remote areas and at the grassroots level, as well as professional title series and posts with low requirements for foreign language level, are not required to have professional titles in foreign languages.

  At present, Guangdong, Shandong, Shaanxi, Guangxi, Anhui, Henan, Shanghai, Fujian, Beijing, Jiangsu, Yunnan and other provinces have made it clear that foreign languages for professional titles are not required uniformly or are not necessary for professional title evaluation.

  In July 2016, Shandong Province no longer made uniform and rigid requirements for the foreign language test for professional titles. When applying for intermediate or below titles, there is no requirement for foreign languages. When applying for senior professional titles, there is no uniform requirement for foreign languages; Need to evaluate the level of foreign language, professional title foreign language test and other government organizations or social recognition of various certificates can be used as a basis, the specific requirements are determined by the senior review committee. According to reports, the scores of CET-4 and CET-6 and TOEFL IELTS can prove their foreign language proficiency. In 2016, the number of people who participated in the evaluation of professional title declaration tripled compared with previous years.

  According to Zhang Shaohong, director of the Personnel Department of Shandong Academy of Social Sciences, foreign languages are no longer a necessary condition for the evaluation of professional titles in 2016. "This is to loosen the talent." Wang Yiping, a researcher at the Institute of Sociology of Shandong Academy of Social Sciences, said that in the social science field, those who are sent abroad and need to know the latest foreign trends, as a researcher, will definitely take the initiative to learn and master foreign languages, and need not be used as a hard lever to evaluate their professional titles.

  In August 2016, the Office of the Leading Group for Professional Title Reform of Henan Province issued the Notice on Adjusting the Foreign Language Policy for Professional and Technical Personnel in our province, stipulating that foreign language for professional titles is no longer a necessary condition for the evaluation of professional and technical positions. According to the characteristics of series, specialty and post, the employer can independently determine whether the foreign language with professional title is a condition for the appointment of professional and technical posts.

  The relevant person in charge of the Henan Provincial Department of Human Resources and Social Security said that the Notice further highlighted the leading role of employers in talent evaluation and talent use, emphasized the talent evaluation orientation of having both ability and political integrity, and paid attention to evaluating talents based on ability, performance and contribution, stripped off the factors that are not closely related to the evaluation of professional titles, and "loosened" professional and technical personnel, so that professional titles returned to the talent evaluation standard recognized by the society in terms of professional and technical level, ability and performance.

  "Not only" does not mean "don’t", but also encourages learning foreign languages.

  The evaluation of professional titles no longer needs to go through the hard lever of foreign language examination. Does it mean that foreign languages are not important?

  "At present, we still have language shortcomings in international communication. The lack of uniform requirements for professional titles in foreign languages does not mean that everyone does not have to learn foreign languages. ‘ Not only ’ Not equal to ‘ Don’t ’ 。” Yu Jiadong said, "At the same time, as China plays an increasingly important role on the world stage, international exchanges are also increasing, whether it is ‘ Belt and Road ’ The implementation of national strategy, the internationalization of talents and the going abroad of China enterprises all require talents’ foreign language level. In addition, the proportion of our employees in international organizations is still relatively low, which also puts forward requirements for learning foreign languages. Therefore, in terms of orientation, we still encourage everyone to study foreign languages hard. "

  According to the relevant person in charge of the Professional and Technical Personnel Management Office of Shandong Provincial Department of Human Resources and Social Security, foreign languages are an important tool for professional and technical personnel to learn and master advanced knowledge and technology and carry out academic and technical exchanges with foreign countries. With the rapid development of science and technology, economic globalization and the accelerating pace of China’s opening to the outside world, it is still a long-term task to improve the foreign language level of professional and technical personnel. According to the needs of professional technology, we should actively encourage and guide the vast number of professional and technical personnel to strengthen their study through various ways and means such as self-study, counseling and examination, highlight their advanced nature, practicality and effectiveness, and constantly improve their foreign language level to better meet the needs of scientific, technological, economic and social development.

  In addition, in order to further implement the requirements of the National Regulations on Continuing Education for Professional and Technical Personnel and promote the continuous improvement of professional and technical personnel’s ability and quality, Shandong encourages and guides foreign languages with professional titles as one of the contents of continuing education, and professional and technical personnel voluntarily choose to take the examination. Those who pass the examination can be converted into corresponding continuing education hours and registered with continuing education certificates.

"Fireworks purchased outside Beijing

 

Can it be shipped back to Beijing for discharge? "

 

 

Not long ago, when the police inspected the vehicle at Fengheying checkpoint, they found five boxes of fireworks and firecrackers in Gao’s car, claiming that they were bought from outside Beijing and had to be brought back to Beijing to set them off … Illegal transportation of fireworks and firecrackers has violated the relevant provisions of the Public Security Administration Punishment Law. At present, Daxing police have imposed administrative detention on Gao for five days according to law.

 

Attention, attention, attention!

 

Don’t transport without a license!

 

No discharge in the forbidden area!

 

 

Recently, when the police patrolled the area, they found six boxes of fireworks and firecrackers in the trunk of a vehicle. Upon inquiry, it was learned that after the car owner Zhang attended a friend’s wedding outside Beijing, the other party gave him the remaining fireworks and firecrackers. Zhang intended to bring it back to his hometown in Shanxi before the Spring Festival, but he was seized by the police before he left. At present, Daxing police have imposed administrative detention on Zhang for 5 days for illegally transporting dangerous substances.

 

I was lucky enough to receive a "big order"

 

And got arrested …

 

 

Recently, the police found 26 boxes of fireworks and firecrackers in a car during their duty. Upon inquiry, they learned that the driver Su Mou took an order from a stranger and asked him to transport fireworks and firecrackers from other places to Beijing. Knowing the relevant laws and regulations, Su was still lucky enough to take orders for transportation, but he did not expect to be seized by the police just after entering Daxing District. At present, the driver Su Mou has been administratively detained by Daxing police for illegally transporting dangerous substances.

 

Police tips

 

Although the beauty of fireworks is romantic, it is illegal to produce, store, manage and transport fireworks and firecrackers without permission, and there are great security risks. At the same time, the general public and friends are reminded that from January 1, 2022, the city has implemented a global ban on fireworks and firecrackers, and no retail outlets for fireworks and firecrackers are set up. Please actively support the safety management of fireworks and firecrackers in Beijing, abide by the ban regulations, and do not set off fireworks and firecrackers (including cold fireworks and children’s toy fireworks) illegally, and consciously resist illegal fireworks and firecrackers.

The man died of heatstroke with a body temperature of 42℃. The doctor told you not to "carry hard" in sauna days, and be alert if you suddenly "have no sweat" after sweating.

Shencheng entered the "roasting" mode.

The hottest day of the year has come! In the past two days, most parts of the country were scorched by the scorching sun. In Shanghai, the temperature also went up all the way, from 33℃, 35℃ and all the way to 38℃, and the outdoor high-temperature barbecue mode was started. With the continuous high-temperature weather, the incidence of heatstroke also increased. Recently, a middle-aged man in Huizhou, Guangdong Province suffered from heatstroke and his body temperature approached 42℃, and he died after being rescued. In this regard, the doctor once again reminded:In high temperature environment, if you have sweating, thirst, chest tightness, dizziness, nausea, limb weakness and numbness, you must pay attention to it. You may have heatstroke, so don’t "carry it hard".

After sleeping, the topic of heatstroke has become one of the most concerned topics of the public, which is not only uncomfortable, but also may have fatal consequences. Recently, "the man died of heatstroke at a temperature of 42℃" directly boarded the hot search.

"The air humidity increases after falling into the air, coupled with continuous high temperature, which is very prone to heatstroke." Zhou Yong, chief physician of the Department of Internal Medicine of Shanghai Renai Hospital, explained that heatstroke is an acute disease with disorder of body temperature regulation, water electrolysis metabolism and dysfunction of nervous system and circulatory system in an environment with high temperature and high fever and no air circulation. Heatstroke is mainly related to high temperature, direct sunlight, high labor intensity, poor air circulation and other factors. In addition, weak personal constitution, poor nutritional status, excessive fatigue, lack of sleep and obesity are also factors that induce heatstroke.

How to judge whether it is heatstroke? Heatstroke can be divided into premonitory heatstroke, mild heatstroke and severe heatstroke. After heatstroke, there will be a series of disease symptoms from light to heavy. Among them, severe heatstroke can be divided into three types: heat spasm, heat exhaustion and heatstroke.Heat stroke is a particularly serious disease. The patient’s body temperature can be as high as 40℃, and he sweats a lot in the early stage, and then "no sweat", accompanied by different degrees of consciousness disorder, and some may even lead to shock, which can seriously cause coma, liver and kidney failure, and even multiple organ failure. The condition deteriorates rapidly and the mortality rate is extremely high.

So, what should I do if I get heatstroke? Dr. Zhou Yong suggested that,Once you feel heatstroke, you should stop your activities immediately, move to a cool and ventilated place, turn on the electric fan or air conditioner, take off your excess clothes and let your body dissipate heat quickly.; People around you can use cold water or alcohol to help patients wipe their bodies, or use wet towels and cold patches to cool them down.

During this period, patients can take summer medicine, drink more light salt water and mung bean soup to replenish lost body fluids, and closely observe the patient’s situation. If the patient is unconscious, or the symptoms are difficult to relieve or disappear, it may be severe heatstroke. At the same time as taking treatment measures, dial "120" in time to send the patient to the hospital for treatment.

How to prevent heatstroke in hot weather? Since the high temperature can’t be avoided, you should take precautions at ordinary times. Dr. Zhou Yong suggested:When the weather is hot, whether you are thirsty or not, you should drink more water, especially when you sweat a lot, you must replenish water in time; Usually eat more vegetables and fruits with high water content and keep enough sleep;Avoid going out at high temperature. If you can’t avoid it, you should prepare sunscreen and sunscreen, and prepare some medicines for heatstroke prevention and cooling.

Talking about how special people spend the midsummer safely, Director Song He of Shanghai Yuanda Cardiothoracic Hospital found that,Many patients with cardiovascular and cerebrovascular diseases have a misunderstanding. They always think that the blood pressure is the lowest in summer and the symptoms are relatively stable, so they stop taking drugs or change their own medicines without authorization. Actually, it is not. High temperature weather is also a high incidence of cardiovascular diseases, especially when the weather continues to be sultry, human metabolism and blood circulation are obviously accelerated, subcutaneous blood vessels are dilated, blood flow is increased by 3-5 times than usual, and the burden on the heart is aggravated.Secondly, the high temperature in summer makes people sweat a lot, and the body’s water evaporates with sweat in large quantities, causing blood viscosity, which is easy to lead to cardiovascular and cerebrovascular ischemia and even embolism.

In addition, hot weather makes people prone to emotional "heatstroke", irritability and irritability, coupled with factors such as long days and short nights and "discounted sleep quality".Patients are prone to angina pectoris, arrhythmia, cerebral infarction, myocardial infarction, and even sudden death.

Therefore, high temperature weather will also bring challenges to patients with cardiovascular and cerebrovascular diseases. Director Song He reminded us to replenish more water and have a light and balanced diet in the dog days. Patients with chronic diseases such as hypertension, heart disease and diabetes should have regular outpatient check-ups, take medicine strictly according to the doctor’s advice, and do not stop taking medicine without authorization. Cardiovascular patients should avoid overwork and spicy diet, and eat more fresh fruits and vegetables. You should avoid activities at high temperature, pay attention to drinking a glass of water in the morning, reduce blood viscosity, keep proper exercise, and avoid great joy, great sorrow and great anger.
