几类函数的留数定理

Theorem of Residue of Several Functions

在传统的留数计算方法的基础上,得到了新的留数计算方法,讨论了函数ф(z)f(n)(z)/f(z)的留数,并研究了该函数分子分母都有零点的情况下,共轭复极点处的留数与留数的共轭是相等的问题。

We obtain new methods which improve calculation of the residue based on traditional calculation of the residue,The residue of ф（z） f（n）（z）/f（z）is discussed,reserach the function,when the numerator and denominator are zero,the residue of conjugate complex poles and the conjugate of residue are equal.
