摘要
文章在截断展开法中采用特殊的函数变换形式,从而求出了广义变系数KdV方程三类新的精确解。这些解更具有一般性,它包含着已有文献给出的精确解析解。
In this paper, by using of new special function transform in truncated expansion method, the three kinds of exact solutions of the general variable coefficient KdV equation are obtained. The solution we obtained presents generality, because it contains some exact analytic solutions that are given in other papers.
