Characters experience, Zheng Zhemin

1924 (13th year of the Republic of China) 654381October 2nd, Mr. Zheng Zhemin was born in Jinan, Shandong Province, and his ancestral home was Yinxian, Zhejiang Province (now Yinzhou District, Ningbo City). His father, Zheng, herded cattle from childhood, studied in private schools and primary schools for several years, then went to town as an apprentice, and later set up a factory in business, advocating industry and educating his children to be diligent, eager to learn, cultivate themselves and raise their sexuality. The family environment has a profound influence on the formation of Mr. Zheng Zhemin's studious and upright personality in his youth.

Mr. Zheng Zhemin went to Jinan Yu Ying Middle School after finishing primary school in Jinan No.5 Primary School.

1937 (26 years of the Republic of China), the second day, War of Resistance against Japanese Aggression broke out, and Mr. Zheng Zhemin entered Sichuan. He studied in Chengdu Jianguo Middle School, Chengdu Huayang County Middle School and Jintang Mingxian Middle School. He studies hard and is willing to do things for everyone. He used to take care of food, run a drama troupe and an English club, and had a strong interest in physics and English. He got excellent grades in all subjects and was beaten by some classmates because he didn't take the exam and cheated.

1943 (32 years of the Republic of China) Mr. Zheng Zhemin graduated from Jintang Mingxian Middle School, was admitted to the Department of Electrical Engineering of Southwest United University with the first place in science and engineering, and transferred to the Department of Mechanical Engineering the following year.

1946 (thirty-five years of the Republic of China), after the victory of the Anti-Japanese War, Zheng Zhemin's engineering school returned to Beiping (now Beijing) Tsinghua Campus, and Mr. Zheng Zhemin continued to study in department of mechanical engineering, Tsinghua University; In the same year, Qian Weichang returned from the United States to teach in Tsinghua University. Zheng Zhemin, a senior, was exposed to modern mechanical theories such as elasticity and fluid mechanics for the first time in his class. Qian Weichang's rigorous and vivid theoretical analysis aroused Zheng Zhemin's great interest and had a far-reaching influence on him.

1947 (thirty-six years of the Republic of China), graduated from Tsinghua University with a bachelor's degree in engineering, and stayed in school as a teaching assistant of Professor Qian Weichang after graduation.

At the end of 1947/at the beginning of 1948, after being selected by Tsinghua University, Beiping, North China and the whole country (North China, Central China and South China), Zheng Zhemin stood out and became the only Rotary international scholarship winner in China. Young Mr. Zheng Zhemin thinks that applied mechanics plays an important role in China's industrial construction, and puts forward that applied mechanics should be his major. At the same time, he listed California Institute of Technology and University of London as recommended schools, and was recommended by Mei Yiqi, Futian Chen, Qian Weichang, Li Jixiang and others. 1948 (thirty-seven years of the Republic of China) In April, his application was approved and he was admitted to California Institute of Technology. In August of the same year, he went to the United States by boat from Shanghai and successfully obtained his master's degree a year later. Then he became a doctoral student of Qian Xuesen, doing research on thermal stress.

1In June, 952, Mr. Zheng Zhemin received his doctorate from California Institute of Technology; After receiving his doctorate, he set out to return to China to participate in the construction of the motherland, but was blocked by the American government.

1954 After the Geneva Conference, the US Immigration Bureau lifted the restriction that a number of international students were not allowed to leave the country, so Zheng Zhemin left the United States by boat from new york on September 26th 1954 and arrived in Switzerland on October 2nd 18.

Zheng Zhemin was able to leave France on February 26th, 2 1 year and enter from Baoan County (now Shenzhen) due to the visa formalities at the passing place and waiting for the sailing date. After returning to China, Mr. Zheng Zhemin first worked as an associate researcher in the Institute of Mathematics of China Academy of Sciences, and then joined the Mechanics Laboratory founded by Qian Weichang. At the end of the same year, Qian Xuesen returned to China, and he immediately founded the Institute of Mechanics of Chinese Academy of Sciences together with Qian Xuesen.

1956 1, the Institute of Mechanics of Chinese Academy of Sciences was established, and Zheng Zhemin became one of the first batch of scientific and technical personnel, serving as the head of the elastic mechanics group to study the earthquake resistance of dams. In the same year, he also participated in the formulation of the national mechanical discipline plan as an assistant in the 12 science and technology development prospect plan hosted by Qian Xuesen. Later, under the guidance of Qian Xuesen, the discipline of explosive mechanics was established in Zheng Zhemin.

From 65438 to 0958, Zheng Zhemin led the scheme demonstration of large hydraulic turbines, and then began to study the theory and application of explosive forming.

In the early 1960s, he expounded the main laws of explosive forming, and cooperated with industrial departments to produce missile parts with high technical requirements, making explosive forming a new process based on scientific laws.

During the period of 1964, Mr. Zheng Zhemin accepted and completed the relevant tasks involving underground nuclear tests, and took the initiative to consider the prediction of underground nuclear explosion power.

1965, Zheng Zhemin and Xie Bomin, together with other countries except China, independently put forward a new mechanical model-fluid elastic-plastic body model. In the same year, he also instructed the ordnance department to carry out a model test of armor-piercing geometric similarity law.

During the Cultural Revolution, Zheng Zhemin's body, mind and scientific research were all impacted. He worked in the May 7th Cadre School in June 55438+July 0970, June 55438+June 09765438 +654381October+June 065438.

197 1 year, Zheng Zhemin returned from the cadre school. In order to change the backward situation of conventional weapons in China, he organized forces to study the armor-piercing mechanism. After 10 years' efforts, a series of problems have been solved, such as the similarity law between armor piercing and armor piercing, the mechanism of armor piercing, the simplified theory of armor piercing, and the stability of jet.

From 65438 to 0978, Mr. Zheng Zhemin was promoted to researcher.

From 65438 to 0979, Zheng Zhemin led the establishment of the laboratory of mechanical properties of materials in the Institute of Mechanics, and served as the first director of the laboratory.

1980 was elected as an academician of China Academy of Sciences (later renamed as an academician).

1February, 984, Zheng Zhemin took over the baton of Qian Xuesen and became the second director of the Institute of Mechanics of Chinese Academy of Sciences.

65438-0986, Zheng Zhemin led and organized the research of marine engineering mechanics, and served as the director of the research center of marine engineering science and technology of China Academy of Sciences.

From 65438 to 0988, Mr. Zheng Zhemin led the establishment of an open research laboratory for nonlinear continuum mechanics, and served as the first director of the laboratory, leading and guiding the basic research on nonlinear mechanical properties of materials and nonlinear behavior of fluids.

1993, Zheng Zhemin was elected as a foreign academician of the American Academy of Engineering for his contribution to explosive mechanics.

From 65438 to 0994, Zheng Zhemin was elected as an academician of China Academy of Engineering.

1In May, 1999, under the planning of academicians Zheng Zhemin and Zeng Hengyi of China Offshore Oil Corporation, Lu Yongxiang, President of China Academy of Sciences, and Wei Liucheng, General Manager of Offshore Oil Corporation, signed the Letter of Intent for the Tenth Five-Year Scientific and Technological Cooperation between China Academy of Sciences and Offshore Oil Corporation.

From 2003 to 2004, Zheng Zhemin, who was nearly eighty years old, was entrusted by the Technical Department of the Chinese Academy of Sciences as the head of the special consulting group of "National Strategic High-tech and High-tech Industrialization Research", and was responsible for organizing high-level experts to make suggestions on the special project "National Medium-and Long-term Science and Technology Development Planning and Development Strategy Research" 13.

Won the highest national science and technology award in 20 13 years and 20 12 years.
