Research professor, consultant and permanent member, Science and Technology Committee, State Commission of Science, Technology and Industry for National Defense.

Cheng has been specialized in theoretical physics for years and is one of the pioneers of Chinese nuclear technology investigations. He jointly presented the 5-dimensional space field theory in the field of quantum mechanics and field theory, derived the Dirac equation under quantum mechanics conditions, relative theory and inertia principle, and proved the kinetic formulation of Mercury’s perihelion by using Einstein’s equivalent principle.In the field of solid state physics, he presented his theory of superconductivity on the basis of the energy band theory and raised criticism against conventional model of electron pair. He presented the generalized themodynamic dissipation theory and obtained important results in modifying the TFD models.

He was elected Member of the Chinese Academy of Sciences in 1980.

函數(shù)論學家。江蘇吳縣人。1940年畢業(yè)于浙江大學并轉為研究生。1949獲美國普林斯頓大學博士學位。北京大學教授。主要從事數(shù)學與應用數(shù)學特別是調(diào)和分析方面的研究與教學工作，并取得多項很有影響的成果。在多重三角級數(shù)唯一性理論、多重富里葉級數(shù)求和與逼近理論方面作出了開創(chuàng)性并有深遠影響的成果。是中國多元調(diào)和分析研究的先驅(qū)和學術帶頭人。對有限華爾希變換作了系統(tǒng)研究，奠定了此變換的理論基礎，為運用此變換于圖像處理提供了理論依據(jù)并作出了優(yōu)秀成果。

1980年當選為中國科學院院士（學部委員）。

Theoretician of functions. Born in Wuxian, Jiangsu Province.Graduated from Zhejiang University in 1940 and continued to study as a postgraduate student. Received Ph.D. from Princeton University, USA in 1949. Professor, Peking University.

Chen has been mainly engaged in the research and education in pure and applied mathematics, especially in harmonic analysis,and obtained lots of very influential results. In his studies of the uniqueness theory of multiple trigonometrical series, summation and approximation theory of multiple Fourious series, he made pioneering achievements of far-reaching effects. He is respected as the pioneer and foregoer in multi-variable harmonic analysis in China. With his systematic studies, he has laid the theoretic foundation for the finite Walsh transformation, provided theoretic basis for applying this trans formation in image processing, and carried out excellent work.

He was elected Member of the Chinese Academy of Sciences in 1980.

Accelerator physicist. Born in Harbin, Heilongjiang Province.Graduated from Yenching University in 1943. Received Ph.D. from Stanford University, USA in 1951. Research professor,Institute of High Energy Physics, Chinese Academy of Sciences.

From the 1950s to 1960s, Xie made many contributions in leading the development of China’s electron linear accelerator,high power klystron, etc.. In the 1980, he guided the design,prefabrication research and construction of the Beijing Electron Positron Collider and made outstanding contributions as the project director. He was later responsible for the development of Beijing Free Electron Laser project which was the first facility in Asia that lased in the IR spectrum region. With decades of research,construction and personnel training in the field of accelerator, he has played an important role in advancing Chinese experimental physics and accelerator physics and technology.

He was elected Member of the Chinese Academy of Sciences in 1980.
