五阶KDV-LIKE方程的精确解

Exact Solutions of a Fifth-order KdV-like Equation

根据齐次平衡原则和F-展开法,求出了五阶KdV-like方程一些用Jacobi椭圆函数表示的双周期解.并且在极限的情况下,得到了孤立波解和三角函数表示的周期波解.

In the paper, according to homogeneous balance principle and F-expantion method,some double-periodic wave exact solutions of a fifth-order KdV-like equation is obtained,in the form of Jacobi elliptic function. Solitary wave solutions and periodic solutions in the form of trigonometrical function can be obtained in their limiting condition.
