三十年来,一直被认为是无可怀疑的物理学基本定律之一——宇称守恒定律,已经被一项新的发现所动摇了。这个有关基本粒子的性质的新发现,是由美国哥伦比亚大学在今年1月16日宣布的,参加这项研究工作的有三位留美的中国物理学家——哥伦比亚大学教授李政道,普林斯顿大学研究院教授杨振宁和哥伦比亚大学副教授吴剑雄(女),以及其他两位美国物理学家贾文博士和莱德曼副教授。
For thirty years, one of the fundamental laws of physics that has long been considered as beyond doubt - the law of conservation of parity - has been shaken by a new discovery. The discovery of the nature of elementary particles was announced by the University of Columbia on January 16 this year. Three Chinese physicists from the United States who participated in the study, Professor Li Zhengdao of Columbia University, Princeton University Research Institute Professor Yang Zhenning and associate professor Wu Jianxiong (female) of Columbia University, as well as two other American physicists, Dr. Jia Wen and Associate Professor Ryderman.
