The deeds of scientist Guo Yonghuai.

In study, work or life, everyone has tried to write deeds. Deeds materials are written materials used to praise the advanced, set a typical example, make the broad masses of cadres and people see Si Qi, apply what they have learned, try their best to do their jobs, and truthfully record and reflect the outstanding deeds of advanced collectives and advanced figures emerging in their work and study. There are many precautions in writing deeds. Are you sure you can write it? The following is the story material of Guo Yonghuai, a scientist, which I compiled for you. It is for reference only and I hope it will help you.

Guo Yonghuai is one of the pioneers of modern mechanics in China. Together with Qian Xuesen, Zhou Peiyuan and Qian Weichang. He planned the setting of mechanics major in China universities. He and mechanics strategized, carefully studied the development direction of modern mechanics, and formulated the short-term development plan and long-term goal of the discipline, which greatly changed the face of China's mechanics discipline, especially the modern mechanics science had a high benchmark from the beginning, and in just a few years it was close to the world advanced level in some aspects.

First, strive to cultivate scientific and technological talents.

As early as before returning to China, Guo Yonghuai discussed with Tan how to train technicians after returning to China. After returning to China, he has always regarded the cultivation of scientific and technological talents as the top priority.

From 65438 to 0956, China resumed the establishment of the postgraduate system. Guo Yonghuai actively planned the postgraduate training of the Institute of Mechanics. The first batch of enrollment, he brought five graduate students himself, and later personally brought several batches. He advocated that the training of talents should be based on "leading by example and teaching by example". In teaching and scientific research, he sets an example and often works with young people to solve specific technical problems. When training graduate students and teaching assistants, he pays attention to improving both theoretical analysis and experimental research. His guidance and help to young people is heuristic and gradual, and the focus is on mastering scientific research methods and improving scientific research skills, not just solving some specific problems. Under his training, many graduate students have become academic leaders or doctoral supervisors.

1957, Guo Yonghuai and Qian Weichang organized and led Tsinghua University mechanics research class. In addition to being responsible for the daily organization of the seminar, he also taught himself an introduction to fluid mechanics. Before the start of the course, he called the tutors, personally led them to visit the laboratories of relevant colleges and universities, inspired some key issues, and then asked them to arrange an experimental plan for the course to combine theory with practice. Before graduation, Guo Yonghuai personally instructed students to arrange graduation thesis topics, and tried to meet with tutors and students every week to understand the progress and help solve problems. Tsinghua University mechanics research class has been held for three times, with more than 290 graduates. Now these students are distributed in various departments of the country, especially in the mechanical departments or teaching and research departments of national defense scientific research units and key universities, and they play a pillar role.

Guo Yonghuai spared no effort in personnel training. During the period of 1958, he also served as the head of the Department of Chemical Physics of China University of Science and Technology, and the professor of the Department of Mathematical Mechanics of Peking University, teaching the high-speed boundary layer. During his teaching, every class was condensed with his painstaking efforts. His comments and analysis of scholars' success or failure experience are enlightening for beginners and even beneficial for life. When it comes to solving various forms of N-S equations, he is always very happy. He chats with Kan Kan and points out what transformation is promising, which road is futile, what problems will be encountered and where the crux lies. Everyone who has listened to his class thinks it is memorable. Lu Shijia often comes to Guo Yonghuai's lectures. She once commented: "Only he can speak so vividly."

Guo Yonghuai is an excellent educator. He compares himself to a stone and is willing to pave the way for the growth of young people. He deeply feels that cultivating a large number of outstanding talents is an important guarantee for the development of science and technology in China. The arduous task of cultivating academic successors occupies a prominent position in his work arrangement. Everything he says and does reflects this. In 196 1, he wrote: "The current plan is to train a group of backbone forces as soon as possible and gradually form a professional team." Then he said with a sigh of relief, "because of several years' work, the effect has been seen." "

Second, devote yourself to China's nuclear weapons cause.

1960 in may, Guo Yonghuai was transferred to the institute of nuclear weapons (nine institutes) and concurrently served as the vice president of the institute. While dealing with the daily work of the Institute of Mechanics, he spent a lot of energy on developing nuclear weapons, which is of great significance to China's political, national defense and scientific and technological development. At the early stage of atomic bomb development, Guo Yonghuai was mainly responsible for the leadership of mechanics.

In the exploration stage of the atomic bomb theory, Guo Yonghuai made great contributions to solving some key problems. For example, there were different views on the detonation mode of the first atomic bomb at that time. By comparing their advantages and disadvantages, Guo Yonghuai strongly supports the policy of "striving for high and preparing low", that is, taking the advanced "implosion method" as the main attack direction. For another example, in the theoretical calculation of explosive detonation wave, Guo Yonghuai correctly proposed the one-dimensional characteristic method, which solved a lot of theoretical and technical problems. In order to let everyone know about detonation, Guo Yonghuai also personally taught explosion mechanics.

In the process of detonation physical test, Guo Yonghuai often went deep into the test site to guide the work and assist the test. At that time, in order to determine the technical scheme of atomic bomb detonation focusing, the debate was very fierce. Chen Nengkuan, a young physicist, put forward a focusing scheme which is difficult and risky, but takes fewer detours. Many people are skeptical about this. Guo Yonghuai repeatedly estimated from the mechanical point of view, and boldly supported the adoption of this scheme. In order to cooperate with the detonation test, Guo Yonghuai also instructed the design personnel to design the structures of different test elements, so that the detonation test can be carried out smoothly.

Guo Yonghuai attached great importance to the weaponization and serialization of nuclear bombs, and often repeatedly stressed at the meeting of the Ninth Academy that efforts should be made to do a good job in the later development of nuclear weapons. In the following process, he has been responsible for the overall structural design, appearance design and environmental simulation experiments. He arranged a series of pre-research topics related to weaponization very early, including structural design, shape design, flight trajectory, physical fuze, environmental test items and equipment. On the structural design of missiles, Guo Yonghuai put forward many unique ideas, including thin shell structure, universal nuclear bomb and so on. They have been gradually implemented in the later work, which is of great significance to the lightweight, actual combat, serialization and experiment of new principles of nuclear weapons.

In environmental testing, Guo Yonghuai has played a leading role in the establishment of environmental testing equipment and the analysis of nuclear weapons in China. He started with the allocation of technicians, the arrangement of subjects, the determination of test items, the preparation of test equipment, etc., so that China has a set of large-scale, precise and extensive equipment, including shock, noise, vibration, overload, temperature and humidity, mold, salt spray and other combined test equipment, large-scale centrifugal testing machine. He also personally went out to discuss with the relevant units to develop special equipment.

Guo Yonghuai's scientific research vision is long-term, and he always has a long-term plan for the weaponization stage in his mind. He proposed that random vibration, high-speed impact and noise tests should be carried out in dynamic environment tests. In order to improve the adaptability of nuclear weapons, he proposed a widening temperature test. At that time, the division of labor was not divided, and Guo Yonghuai's attention often went beyond the field of mechanics. He pays special attention to the research on the subject of "safety demonstration". "Safety demonstration" is to study whether and how the aircraft can safely escape the threat of optical radiation and shock wave after dropping nuclear weapons. In order to ensure absolute safety, Guo Yonghuai strongly advocated the combination of theoretical calculation and model airdrop test. To this end, he also personally questioned and participated in the calculation of the flight trajectory and ballistic characteristics of nuclear aviation bombs and hydrogen bombs during airdrop. At his initiative, after strict calculation and analysis, every nuclear test plane returned safely.

His contributions to China's nuclear weapons cause are manifold. For example, he put forward many suggestions and ideas about the serial development of nuclear weapons; He directed underwater explosion mechanics research, water tunnel test and anti-submarine nuclear weapons investigation; It also promoted the research and development of submarine missiles. In addition, Guo Yonghuai also put forward important ideas on China's nuclear weapons research system to meet the needs of the combination of the two bombs.

1968 10, Guo Yonghuai went to Qinghai again to plan the thermonuclear weapon test of China's first missile. Before leaving Qinghai, he made an evaluation speech on this national experiment. At that time, there was a problem of "the probability of premature fire" in the experimental theory; In the experiment, there are problems in the design of the new structure of the inner ball; Material processing is considering the self-heating, assembly and storage of products; In the whole system, there is a problem of "missile, umbrella and plane" coordination. Looking forward to 1969 and its future tasks from the preparation of this hot test, Guo Yonghuai boldly proposed to reconsider the above problems in the future design, which pointed out the direction for the mobility, safety and miniaturization of China's nuclear weapons. On February 5th, 65438, Guo Yonghuai flew back to Beijing from Lanzhou. When the plane landed at Beijing airport, there was a first-class accident, and Guo Yonghuai was killed in the line of duty.

Guo Yonghuai devoted his whole life to China's mechanics and national defense science and technology. It is amazing how much work he has done in a short period of 12 years after returning to China. Participated in the development of small surface-to-air missiles, hydrogen-oxygen engines and anti-missile missiles in China; He translated and published Pelant's masterpiece "Introduction to Fluid Mechanics" and organized the translation of "Explosive Mechanics". He used to be the editor-in-chief of Mechanical Journal and Mechanical Translation. He is a director of China theoretical and applied mechanics Society and vice chairman of China Aviation Society. Guo Yonghuai's academic achievements and noble moral character are admired and admired by people. In memory of him, China Science Publishing House published the Collected Works of Guo Yonghuai and Guo Yonghuai in 1982 and 1990 respectively. 1988 65438+On February 5th, a white marble statue was erected for Guo Yonghuai in the shade of the east side of Institute of Mechanics, Chinese Academy of Sciences. The glorious image of Guo Yonghuai will last forever.
