一类多值函数的单值化方法

The Single-valued Method of A Class of Multi-valued Functions

对于具有多个有限支点的根式函数f(z)=■np(z),现行教材已得到了求其某个特定解析分支上函数值的方法.文章给出了计算根式函数的另一种方法,即若曲线C穿过支割线时的情况.

For the radical function f（z）=n P（z）, with multi-branch points, Current textbooks obtains a general method to get the function value on the given branch of analytic function. In the paper, there will be another method for solving radical functions,in other words , it is the condition when C is passing through the support secant.
