在许多工程技术领域(如电磁场理论、量子力学、固体物理、材 料物理、流体力学等)经常遇到复变量的函数.复变函数理论研究复 变量之间的对应关系,它是实变函数理论在复数域中的推广,因此两 者之间有许多相近之处,这有助于我们学习比较,但在学习中更要注 意它们之间的不同之处.本章主要讨论复变函数的一些基本概念

When in 1920 I resumed my studies of theoretical physics which had long been interrupted by circumstances beyond my control, I was far from the idea that my studies would bring me several years later to receive such a higl and envied prize as that awarded by the Swedish Academy of Sciences each year to a scientist: the Nobel Prize for Physics. What at that time drew me towards theoretical physics was not the hope that such a high distinction

整个科学的发展与全人类的文化是分不开的,在西方是这样,在中国也是如此。可是科 学的发展在西方与中国并不完全一样。在西方,尤其是如果把希腊文化也算作西方文化的话, 可以说,近代西方科学的发展和古希腊有更密切的联系。在古希腊时也和现代的想法基本相 似,即觉得要了解宇宙的构造,就要追问最后的元素是什么

Nobel Lecture december 13. 1946 The history of the discovery of the exclusion principle m, for which I have received the honor of the Nobel Prize award in the year 1945, goes back to my students days in Munich. While, in school in Vienna, I had already ob- tained some knowledge of classical physics and the then new Einstein rel- ativity theory, it was at the University of Munich that I was introduced by Sommerfeld to the structure of the atom- somewhat strange from the point of view of classical physics. I was not spared the which every
