| 摘 要： | 探讨了复合解析函数零点阶数的计算,证明了当z=z0是f(z)的m阶零点,ξ0=f(z0)是g(ξ)的n阶零点,则z0是复合函数w=gf(z)]的m·n阶零点,并结合实例阐述了这种方法的简便性.

| Abstract: | This paper studies the calculation for the order of zeros for compound analytic functions. The authors show that the zo is m . n orders of zero for compound analytic function w =gf（z） ] when z =z0 is m orders of zero forf（z） and ξ0 =f（z0） with n orders of zero for g（ξ）. This simple method is explained with examples. |
