摘要
该文从枝点定义出发,利用亚纯函数（包括整函数）的性质和幅角原理,给出了亚纯函数的对数这一类多值解析函数的枝点的几个判定条件。
In this paper,some conditions of judgement about the branch points of logarithm of meromorphic function,which is a kind of multivalued analytic functions,are given by means of the definition of branch point, the characterizations of meromorphic function (include integral function)and amplituded theory.
