| 摘 要： | 利用特殊的截断展开方法求出了变系数KdV方程的孤子解．其基本思想是假定该方程的形式解具有截断展开形式，以致可把变系数KdV方程转化为一组待定函数的方程组．进而给出待定函数容易积分的常微分方程。

| Abstract: | By using of the special truncated expansion, the soliton-like generalixed KdV equation with variable coefficients is obtained. In this method, the form solution is assumed as the truncated expansion form which is based on the idea that the generalized KdV equation with variable coefficients is reduced to a set of algebraic e-quations of undetermined tunctions, so that we can obtain a set of ordinary defferential equations of undetermined functions which are easily integrated. |
