通过分析论证,说明了中国理论物理学家张宗燧对约束系统的量子化作出了重要的贡献。他于1946年指出了此前的有关约束系统哈密顿正则形式的研究,由于没有正确地处理其中的一个关键问题——不定乘子问题,因此不能用来实现量子化,同时,首先提出了一种解决了这个问题的对于许多约束系统可行的量子化方案。
This paper demonstrates an important contribution by T.S.Chang,a Chinese theoretical physicist,to the quantization of constrained Hamiltonian systems through textual research and analysis.It shows that in 1946 Chang pointed out that the previous studies about Hamiltonian canonical forms of constrained systems can not pass to quantum theory because these studies did not deal properly with one of the key issues,that is,undetermined multipliers.Meanwhile,he was the first to work out a feasible formulation of quantization which could solve this problem in many constrained systems.
