摘要
利用双曲正切函数方法求出了推广kdv方程的孤立波解，其求解过程是初等的、直接的，而且给出了更一般形式的孤立波解。关键词##4推广的kdv方程;;双曲正切法;;
The generalized kdv equation is a model equation with extensive physics background. Thesolitary wave solution is expressed in terms of hyperbolic tangent function in this paper. Thus thegeneralized kdv equation is converted into nonlinear algebraic equation and the generalized form ofsolitary wave solution is obtained.
