The most "young" alumni of the Southwest United University left, and once brought Nanchang University into 211

not

He is like a big director

Directed a drama of the development of the national energy and equipment industry

Pan Jiyi once said that he had done two more fulfilling things in his life. One was to establish a welding major in China, and the other was to build Nanchang University.

On April 19, 2022, Academician Pan Ji, 95, died.

Cai Zhipeng, a core member of the Pan Jizhen Research Team and a researcher at the Department of Mechanical Engineering of Tsinghua University, believes that Pan Jizhen is like a big director and directed a drama of the development of the national energy and equipment industry; and like an architect, he built a big stage for the team. He is like a heavy rain. You are a big tree that can get enough rain, and you can be fully nourished by the grass.

A good principal

In the fall of 1992, the country began to implement the "211 Project".

There was a tradition of education in Jiangxi, but at the time, there was no national key university in the province. A large number of graduates flowed to foreign universities outside the province, so that the poorly developed province's sense of anxiety was anxious.

To this end, Jiangxi has set up a "building a key university leadership group". The State Education Commission stated that it supports Jiangxi Office of 211 universities, but two conditions are mentioned: one is to invest at least 1 billion in the province, and the other is to merge Jiangxi University and Jiangxi University of Technology. Jiangxi agreed that the two schools after the merger were named Nanchang University.

"Tian Shi" and "geographical interest" have a bad "people" -on a good principal.

Entrusted by the Provincial Party Committee, at the end of 1992, the Jiangxi Provincial Education Commission held a symposium on a member of the Jiangxi Academy of Sciences (renamed "academician"). At this meeting, Jiangxi aimed at Pan Ji, the director of the Department of Mechanical Engineering of Tsinghua University and the director of the Tsinghua Academic Committee.

At the end of the year, Wu Guanzheng, then governor of Jiangxi Province, borrowed the opportunity of his alma mater, and asked Tsinghua University leaders to recommend the president. The first candidate recommended by the school was Pan Jizhen.

At the beginning, Jiangxi proposed that in order to influence Pan Jizhen's academic activities and health, even if he goes to the name, it is okay for specific affairs to do less or not, but Pan Jizhen's most disliked is the famous move, so he did not accept it. After learning that Pan Jiyi "either you don't go, you have to be famous and realistic", the Jiangxi side expressed that he could not ask for it and fully support it.

In April, Pan Jizhen took office. In order to support his work, Zhou Shaosen, deputy director of the Provincial Education Commission of the Jiangxi Provincial Party Committee, also served as the party committee secretary of the school.

Jiangxi was treated with Pan Jizhen with "deputy provincial" treatment. His salary and housing are directly expending by the provincial finance. A two -story building he lives is close to the dormitory area of ​​the teaching worker. There is a small courtyard of dozens of square meters, which is facing a lotus pond. Quiet.

At that time, Jiangxi province's fiscal revenue was less than 5 billion, and the provincial level was less than 1 billion. Air conditioner. Within three years, Jiangxi Province invested hundreds of millions of yuan to Nanchang University.

Pan Jiyi found that some hospitals used funding to decorate the office, conference rooms, buy tables and chairs and benches, and did not really use teaching and scientific research. We did not use these money well, so we sorry for 40 million Jiangxi Father. "He asked the school to formulate a system for use of funds.

The school implements the principal under the leadership of the party committee. Zhou Shaosen recalled that Pan Jiyi is the largest talent introduced by Jiangxi Province. The Provincial Party Committee and Provincial Government cares about him, respect and add, and the school party committee also respects him very much.

Xu Liping, the teaching staff of the Chinese Department of Jiangxi University, was transferred to the secretary department of the President's Office of Nanchang University after the merger. She told "China News Weekly" that Pan Jizhen's temperament is elegant, with a wide range of vision. He has a fair position, and everything is beneficial to the development of the school as a starting point.

Pan Jizhen completed the layout and cadre adjustment of the management agency three months after taking office. Xu Liping went to the province with Pan Jizhen. The leader of the Education Commission suggested that he must grasp the financial power and personnel rights, otherwise the principal would be difficult to be. He said: "I don't grasp these things, I only grasp the discipline construction, these vice presidents to catch."

In order to reverse the style of academic style, he began to implement teaching reforms based on credit systems and elimination systems.

He made a detailed explanation at the first school faculty and staff congress. He said that in order to do a university, you must create a free activity space, and a very loose academic environment can make talents. When he was studying in the Southwest United University, some people graduated in four years, some graduated in five years, and some even graduated in eight years. The current university does not have this atmosphere. The reason is that one is not strict, the other is not loose, and higher education should be a diversified model. "Where is our creativity? To a large extent, it is caused by the long -term education 'one -size -fits -all'. Everyone has no possibility and space for free development."

In September 1993, Nanchang University's metal plastic processing major became the first doctoral award point in Jiangxi Province. In 1996, Nanchang University became the first local university in the country to pass the National Education Commission's 2111 pre -trial. Jiangxi's "three -none" situation of higher education in Jiangxi has no key universities, members of the department, and no doctoral points.

Nanchang University has become a typical typical of the merger in this round of teaching reform. Li Lanqing mentioned several times in the "Education Interview Records" that Nanchang University believed that it brought a good start to the reform of college management systems. Zhou Shaosen said that the merger of this round of universities has always had different views and has indeed different results, but the merger of Nanchang University is generally considered success. Pan Jizhen's educational reform in Jiangxi, with underdeveloped economy and poor universities, has successfully entered the 211 project in Nanchang University.

At the end of 2002, Pan Jizheng retired, renamed the honorary president of Nanchang University, and returned to Tsinghua University.

National treasure expert

One day in June and July 2008, Cai Zhipeng, an associate researcher at the Department of Mechanical Engineering of Tsinghua University, rode to the Tsinghua Welding Hall. When he saw that Chen Bingsen, 75, was not far ahead, he caught up and greeted him. Chen Bingsen asked him what he was doing recently. He said that Mr. Pan's high -speed rail project also had some summary work. In addition, there was a research project from the National Natural Science Foundation of China.

"Mr. Pan's high -speed rail project" is the first national intercity high -speed railway, the Beijing -Tianjin high -speed railway built on the eve of the Beijing Olympics. This is China's first seamless high -speed rail. When the rails leave the factory, each section is 100 meters long, and five rails should be welded together in the workshop, and then it is laid and welded on the line. From Beijing to Tianjin 120 kilometers, there are thousands of welded joints, and there are no gaps at all. In two years, Pan Jizhen led the research team to inspect the quality of the rail welding.

After chatting a few words, Chen Bingsen asked Cai Zhipeng slightly, do you want to do a big project with Teacher Pan? Cai Zhipeng said without thinking, of course, thinking about it. Chen Bingsen also said that this project may not be approved, and you have to "bring dry food". Would you like to do it? He said, following Teacher Pan, there is no problem.

After a few days, Cai Zhipeng should come to Panji's office. Pan Jiyi told him that now there is a big task of the country to engage in a low -voltage rotor of nuclear power, and it takes a long time to go to the scene with the Shanghai Steam Turbine Machine Factory and want to hear his opinions.

As early as the early 1960s, Tsinghua University cooperated with several units such as the Shanghai Steam Turbine Factory and completed the first large -scale welding rotor in China for the 6000 kW gas turbine group. This time, the Shanghai Steam Turbine Factory hopes to cooperate with Tsinghua University again. The leaders in the factory said that the low -voltage rotor of nuclear power is a major card neck problem that the country is urgent in large -scale nuclear power construction in the upcoming large -scale nuclear power construction. I hope that Tsinghua's "national treasure -level expert" can continue to provide technical guidance for research.

The background of this incident is that in 2007, China officially released the "Special Plan for Nuclear Power Development (2005-2020)".

The key components of the construction of millions of millions of nuclear power are extra large low -voltage rotors. The rotor is the core component of the turbine. It is divided into two types: welding and overall forging. The former is only produced by French Albes, and the latter only has the capacity of the Japanese Steel Main Steel (JSW) and South Korea Dushan Heavy Industries. The million -kilowatt -class nuclear power low -voltage rotor that China has built and under construction all relies on imports, so independent development of low -voltage rotor has become the key to China's development nuclear power.

According to national planning, the development of the "two leg walking" is implemented, which not only develops the overall forging rotor, but also develops welding rotors.

Cai Zhipeng told "China News Weekly" that in the study, Pan Jizhen always chased a question: What are the benefits of welding rotor than to a whole forged rotor? Everyone discussed and discussed, and never answered this question completely.

Pan Jizhen decided to hold an academic seminar, and thoroughly figured out the differences between these two rotors from technology to national planning.

Yao Eryi, a senior expert in Shanghai Steam Wonders and Alumni, to Tsinghua University, to introduce the situation to Tsinghua. In the factory, a domestic and foreign survey report on the comparison of welding and the comparison of the whole forged rotor, Yao Eryi brought a brief version of the report festival. This is a precious internal information that allows Pan Jizhen to basically grasp the characteristics of welding rotor.

In October 2008, a large -scale electrical welding rotor development exchange meeting was held at Beijing Guohong Hotel. At that time, the entire forging route of the Japanese Steel made the world leading the world. The leaders of the Guangdong Nuclear Power Group of China participating in the meeting proposed the problem of welding residual stress, which expressed concern about whether the domestic welding rotor could be applied. Pan Jiyi clearly stated that the main technical way to create large rotor should be welding, not for the whole forging casting. At that time, this view was advanced.

After the meeting, Pan Jizhen was hired as chief scientists in the development of large nuclear power low -voltage welding rotations, and coordinated with Shanghai Electric, Tsinghua, Harbin Welding Research Institute and Shanghai Jiaotong University. At the same time, the state supports the "one heavy" (China First Heavy Machinery Group) and "Double" (China Second Machinery Group) to carry out the research and development of large -scale rectification rotors.

In January 2009, the Tsinghua research team was initially established and continued to expand. In the team, there were both old -generation scientists who participated in the development of the first air -pellet welding rotor in China.

Welding residual stress is a special concern for the research group and customers. Cai Zhipeng brought an assistant to the Shanghai Steam Turbine Factory to measure the distribution of welding rotor residual stress, and evaluated the effect of key process technology on reducing stress.

Cai Zhipeng reported the measurement results to the research team. Pan Jizhen was very happy and evaluated them to "make the leader." He also reported to the leaders of the Shanghai Steam Turbine Factory, and the other party was also very happy to praise Mr. Pan's new generation team to maintain a style of Tsinghua. Deputy Chief Craftsman Shen Hongwei said to him with a smile that every time he saw Teacher Pan, he did not dare to speak easily, because every time he met, Mr. Pan was sitting next to him. How can other units have such top teams. Pan Jiyi divided the research team into several groups and held a meeting every week. The team also has an academic lunch every week, a collective basketball or swimming event, and organizes the entire group report every two or three weeks. Under the leadership of Chen Bingsen, Ren Jialie, and Lu Anbi around Pan Jizhen and around him, the research team grew rapidly.

Cai Zhipeng discovered that Pan Jiyi was always in Wenwen Erya in the subject group, and he didn't speak much, but he had a lot of aura outside the meeting. Each sentence was cut off, which was very important. He treats others and is friendly, but he can always seize important key issues. Zhao Jiancang, chief scientist of CGN, has touched him for the first time, and admires his style.

Cai Zhipeng himself also came to the body that Pan Jizhen was full of academic democratic atmosphere, which was really fascinating. He said that during that time he could feel his growth every day, it was a particularly beautiful time, like "the years of passion burning."

A dial of Pan Jiyi in 2010 made him "a lot".

At that time, the research team continued to have new topics, and the state of development was good, but they could not publish the dissertation. This is due to the needs of conservative business secrets, and the second is because of the dissertation to involve the energy of the assault. However, there was some conflicts with the school's assessment indicators, and the differences in college culture and factory culture also brought some misunderstandings. Cai Zhipeng was quite troubled and went to Pan Jizhen for help.

After listening to hearing, Pan Jiyi told him: "You need to let go of these little things. Now you have got a research platform that others have not encountered. You should be determined to become an expert in the field of heat -resistant steel welding metallurgical ten years later. A few words made him feel the feeling of seeing the sun.

In October 2011, Pan Jizhen was invited to participate in the nuclear -welding rotor technology appraisal organized by the National Nuclear Power Technology Company. At this meeting, for the first time, welding adjustment to the main technical route of manufacturing nuclear power low -voltage rotor proves the predictions of Pan Jizhen in 2008.

Nevertheless, users are still watching. After all, the welding rotor has never been applied to a million kilowatt -class steam turbine.

In order to make it easier for users to accept a million -core power low -voltage welding rotor, Shanghai Steam Turbine Factory in 2010 specially developed a super -supercritical million hemo -electric low -voltage welding rotor. The large nuclear power turbine is a semi -speed unit, and the thermal power is a full -speed unit. In contrast, the thermal power unit has more loads and frequently start and stop. Before that, millions of thermal power used to use low -voltage rectification rotors, so after this rotor was successfully developed, no user was willing to use it.

In 2012, the SAIC plant was preparing to hold a technical appraisal of a large -scale welding rotor in Beijing. Shen Hongwei asked Cai Zhipeng to discuss. One was to invite Pan Jizhen as the director of the appraisal committee, and the other was to make Tsinghua a technical report.

After Cai Zhipeng returned to report, the research team met. Everyone thinks that there is no problem with Pan Jizheng as the director of the appraisal committee, but isn't Tsinghua's technical report? Isn't it an athlete and a referee? It is Pan Jizhen's shooting. As long as it is good for promoting the welding rotor and is good for the country, it should be responsible.

Cai Zhipeng suggested that Tsinghua is a third -party status, from an academic perspective, the reliability of welding rotor, so that it does not affect the logical relationship of the appraisal. This suggestion was recognized by everyone. He also boldly made a suggestion that the core content of the report should be that the welding rotor "weak links are not weak".

After he told Shen Hongwei this idea, Shen Hongwei didn't speak for a long time. After thinking about it for a long time, he said it according to Tsinghua's idea. He later said that at that time, he was worried that users had worried about their concerns, and then introduced the weak links to worsen if they would be more snowy.

In May 2012, the technical appraisal will be held. On behalf of a third party, Cai Zhipeng made a technical report. For the first time, the weakest data of the welding rotor developed by the SAIC plant was for the first time, and the test curve provided a test curve.

After listening to the report, the former deputy minister of the Ministry of Machinery Industry Lu Yanzheng first spoke. He said excitedly: "For such a long time, I have been struggling with the safety and urgency of welding rotors. Today I finally rest assured that our welding rotor can be used. Tsinghua's work really clearly explains the welding welding. Why is the rotor safe? "

This meeting is a turning point for large welding rotor breakthroughs in the application link. Only one week after the meeting, users visited the SAIC factory on the spot. After two weeks, they signed a business agreement, and the second product manufacturing was completed after one year. In February 2014, the crew of welding rotors was successfully put into operation, which refreshed the world record of the power generation efficiency of thermal power crew at that time.

"Post -90s"

In 2011, Pan Jiyi suddenly felt chest tight when walking.

After the inspection, it was found that Pan Jizhen's heart was blocked by 90 %. 70 % of the average person will have obvious discomfort, but he focuses on the subject and does not feel it. At this time, the bracket can no longer be placed, and a bridge is needed.

Pan Jizhen is 84 years old this year. He is close to the oldest record of bridge operations at Fuwai Hospital, but he is calm and confident in his body. He really recovered quickly, and he rode an electric bicycle to work in the Tsinghua Welding Pavilion 51 days after surgery. In 2012, Pan Jizhen recovered, the rotor project progressed smoothly, and young members of the team grew up. In Cai Zhipeng's words, there is no more exciting tension since then.

In 2012, the Tsinghua team and SAIC jointly conducted research on the 700 ° C super super criticalrmal crew. During the "Thirteenth Five -Year Plan" period, with the adjustment of the national energy policy, and the overall cost performance of the 700 ° C unit is not very high, this project is temporarily put on hold, but by the "Fourteenth Five -Year Plan" period (2021 ~ 2025), with the surrounding energy situation situation, with the surrounding energy situation situation The uncertainty gradually increased, and the state adjusted the 700 ℃ unit to a 650 ℃ commercial model. Cai Zhipeng said that the results of their team are simply "dimensional promotion", and their research results can be applied to large -scale application.

The welding hall is located in a three -story old building built in 1955. At that time, Pan Jizhen, Chen Bingsen and others planned to build a Tsinghua welding major here. At the end of the corridor on the north side of the first floor, Pan Jizhen's office. In the small conference room next to his office, there were work meetings almost every week. Pan Jizhen, Ren Jialie, Chen Bingsen, and Lu Anbu have always insisted on participating. A conference table and chair are full of space. In order to facilitate the old gentlemen, the students will sit inside each time and leave them to them.

In 2016, the Tsinghua Machinery Department moved from the welding hall to the newly built Li Zhaoji building. After moving, the important activities of the research group will still notify several old gentlemen in time. Pan Jizhen will participate on time every time, even if you do not meet, you like to go to the laboratory, saying that you ca n’t live at home.

He will listen carefully to what everyone says, even if it is a very small thing, he will carefully analyze and discuss. He ordered the students in the morning and asked the progress at noon. The students have developed the habit of finishing today.

The calendar on the wall of the family records his compact schedule. There is almost no one -day idle, and there are countless large and small meetings. Sometimes they have to travel four times a month.

He has a free computer and mobile phone operation. The operating system is always the latest version. You can use QQ and WeChat proficiently, and use PPT as an electronic New Year card. Occasionally, when I encountered a problem, I shouted the graduate students to demonstrate in front of them, and I could soon be able to understand it.

He is always interested. He likes to drink strong tea with a large brown bottle with a Nestlé coffee. When checking the report in the hospital, he will let the secretary accompany him to the restaurant downstairs to eat a burger, drink cola, and like to eat ice cream in the summer. Essence

He often rides his own electric bicycle, traveling through the campus from the northernmost puppet of the school, through the campus, and driving to the southern Li Zhaoji building. Later, his "car" was replaced with three -wheeled and four -wheeled electric vehicles. In 2017, he participated in the recording of the CCTV "Lang Reader" program. The photo of his wife Li Shiyu through the campus of the electric bicycle to make him a "net red".

He is the president of the Beijing Alumni Association of the Southwest United University. He always spares no effort to organize activities and speeches to publicize the college concept of the United University and the spirit of resoluteness and spirit. In 1944, he was admitted to the Department of Machinery Department of the Southwest United University. Conference affairs and website maintenance.

On November 3, 2012, the 75th anniversary of the establishment of the Southwest United University, Pan Jizhen made a report on "The Revelation of the Apocalypse of the Southwest UN General Assembly" at the meeting. The PPT he reported was always prepared by himself, and asked students at most to have a little material. This PPT is made of templates of "welding cutting -edge technology". The above lists "strict teaching requirements, loose teaching environment", "highly democratic style, good -hearted patriotism", "strong academic atmosphere, free academic environment "Wait for revelation.

The average old gentlemen of 90 years of age are very individual. Most of them have declined to pick up and drop off, insist on taking a taxi and taking the bus by themselves. The team surveyed the weather in Beijing in the past 20 years and found that the probability of raining in this day was very high. In the school, 200 volunteers were recruited and distributed to the surrounding bus stations and subway entrances. As a result, that day, it turned out to be small to the middle rain.

Cai Zhipeng watched the team members in an orderly manner at the venue. The volunteers who admired and admired the old scholars such as Yang Zhenning and other "post -90s" scholars, and they felt inexplicable in their hearts.
