摘要
为了求非线性发展方程的孤立波解,提出了齐次平衡法的扩展应用.在此基础上,得到2+1维耗散长波方程组的椭圆周期解.这种方法也可用于求大量非线性发展方程的精确解.
The extended homogenous balance method is applied to find solitary wave solutions of nonlinear evolution equations. Some new exact elliptic periodic solutions of the dispersive long wave equations in 2 ＋ 1 dimensions are obtained by using the method. This method also can be applied to find exact solutions of a lot of nonlinear evolution equations.
