　　曹怀信编著的《复变函数引论(第2版)》简介：For several years, I have been

conducting courses in Complex Analysis, Real Analysis and

Functional Analysis in a so-called "bilingual" way. That is, the

lessons are given with Chinese textbooks, but mainly teached in

English. The main purpose of teaching in this way is to improve the

undergraduate students' ability to read and write English. Using a

Chinese textbook in such "bilingual" courses is not, however,

useful for training students' ability of English-thinking.

Consequently, although there are a number of books on complex

analysis in Chinese, in order to meet the requirements of bilingual

teaching, it is necessary to write a textbook on complex analysis

in English for Chinese undergraduate students. This is just the

main aim of compiling the present book.
