摘要
提出一种推广的求解非线性波动方程精确孤波解的双曲函数展开方法,借助符号计算Maple,应用该方法得到了2个非线性波动方程的精确孤立波解,其中包括一些由4个双曲函数组成的新解。结果表明该方法简单有效,并且可以应用到其它的非线性波动方程。
A generalized hyperbolic function expansion method is proposed to obtain exact solitary wave solutions of two nonlinear wave equations with the aid of Maple. Some of the new solutions are made up of four hyperbolic functions. The results show the method is simple and effective and can be applied to other nonlinear wave equations.
