判别奇点的函数代换方法

The Method of Distinguishing the Order of a Singularity by the Function Replacement

在判别奇点的类型以及极点的阶数时，对某些问题进行适当的函数替换，可使问题变得简单。本文给出了替换的方法并作了证明。

When distinguish the type of the order of the singularity and the order of the extreme value poimt,it can make the problem more simple by a proper fuution neplacement. In this paper we give the method of the neplace ment and prove it.
