两个非线性演化方程的孤立波解

<title>Solitary Wave Solutions to Two Evolution Equations

利用新近提出的一种直接代数方法,在计算机代数系统Maple上系统求解了广义Fisher方程和Sine Gordon方程,获得了它们的精确孤立波解。

<Abstrcat>With the aid of symbolic manipulation system Maple by the direct algebra method proposed recently, generalized Fisher equation and SineGorden equation are studied, and thus some important solitary wave solutions are obtained.
