摘要
介绍格林函数的定义、求法和一般表达式，并就定态势散射和时间相关势散射两种情况分别进行讨论，求出相应的格林函数并得到散射波函数的各级近似，最后求得微分散射截面。
The definition, solving method and general expression of Green's function are in-troduced. The scattering problems of stationary potential and time-dependent potential are studied respective-ly.The Green's functions and all order approximations of scattering wave functions are obtained corre-spondingly.Finally the scattering differential cross section is calculated.
