杨乐1939.11.10～

数学家。江苏南通人。1962年毕业于北京大学，并考取为中国科学院数学研究所研究生。中国科学院数学研究所研究员、所长。主要从事复分析研究。70年代对整函数与亚纯函数亏值与波莱尔方向间的联系作了深入研究，与张广厚合作最先发现并建立了这两个基本概念之间的具体联系。对亚纯函数奇异方向进行了深入研究，引进了新的奇异方向并对奇异方向的分布给出了完备的解答。对全纯与亚纯函数族的正规性问题进行了系统研究，建立了正规性与不动点间的联系。与英国学者合作解决了著名数学家立特沃德的一个猜想。对亚纯函数的导数的总亏量与整函数的亏值数目做出了精确估计。

1980年当选为中国科学院院士（学部委员）。

Yang is mainly engaged in the research on complex analysis.In the 1970s, he made further study on the relation between deficient values and Borel directions of entire and meromorphic functions.Cooperated with Zhang Guanghou , he first discovered and established the detailed relation between these two basic concepts.He made further study on singular directions of meromorphic functions, introduced a new kind of singular directions and gave the perfect solution to the distribution of singular directions.He systematically studied the normality for families of holomorphic or meromorphic functions and established the relationship between the normality and fixed point.He and a British mathematician solved a conjecture posed by the exact estimation on the total deficiency of derivatives of meromorphic functions and the number of deficient values of entire functions.

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

Nuclear physicist.Born in Changzhou, Jiangsu Province.Graduated from the Department of Physics, Central University in 1937.Received Ph.D.from the University of Liverpool, UK in 1950.Research professor, director and honorary director, Institute of Modern Physics, Chinese Academy of Sciences.

Yang was mainly engaged in the development of static accelerator, Cockcrost-Walton and heavy ion accelerator and the research on experimental nuclear physics and he obtained many important results.From the 1950s, he and Zhao Zhongyao led the development of China’s first static accelerator.He took charge of instructing the preparation of the flashing crystals of NaⅠ(T1)and other compounds and developing China’s first Cockroft-Walton accelerator.He organized and led the construction of Lanzhou heavy ion accelerator and the experimental research of heavy ion nuclear physics.He got many original results in the above-mentioned work.

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