| 摘 要： | 利用双曲函数方法求解一类非线性波动方程的精确行波解，得到了若干其它方法不曾给出的新的精确解.这种方法的基本原理是利用非线性波方程孤立波解的局部特点，将方程的孤立波解表示为双曲函数的多项式，从而将非线性波动方程的求解问题转化为非线性代数方程组的求解问题.

| Abstract: | The hyperbolic function method has been used to study new exact travelling wave solutions for a class of nonlinear evolution equation. The basic idea of this method is based on the fact that solitary wave solution of the nonlinear evolution equations is essentially of a localized property.Because the travelling wave solution can assum the polynomial form of the hyperbolic functions, the resultant solutions are obtained by solving a systems of nonlinear algebraic equations. |
