量子电动力学重整化理论的形成

THE FORMATION OF RENORMALIZATION THEORY IN QUANTUM ELECTRODYNAMICS

全面系统地论述了量子电动力学重整化理论的形成过程。介绍了 2 0世纪 30年代发现的量子电动力学的发散困难 ,考查了同一时期的实验状况 ,介绍了促使重整化理论形成的两个关键实验 :兰姆位移和电子的反常磁矩实验 ,着重研究了施温格、朝永振一郎、费曼和戴逊提出各自的量子电动力学重整化理论及其关于重整化理论的物理思想。

This paper presents the theoretical and experimental development of the renormalization theory in quantum electrodynamics,First it outlines the status of the devergence difficulty in QED in the 1930s.Secondly,it focuses on the experimental situation in 1930s.Thirdly it examines the important experiments such as Lamb shift and the anomalous magnetic of electron.Then it concentrates on the process in which Schwinger,Tomonaga.Feynman and Dyson developed their own renormalization theory and their physical ideas.
