直线上的主值积分换序问题分析

Analysis of Exchanging Order of the Singular Integral in Line

采用复变函数的方法 ,讨论了直线上的主值积分换序问题 ,得出了其换序公式 ,并将其结果与 Poincare-Bertrand公式进行了比较和分析 .

In this paper,the exchanging order of singular integral in line is discussed by the complex variable method.We obtain the formula of exchanging order and compare it with the Poincare-Bertrand formula.This formula is useful in solving singular integral formula.
