摘要
介绍了Hereman等提出的构造非线性发展方程孤波解的混合指数方法 .依据数学机械化思想对该方法进行了改进和完善 ,使之能够求得非线性发展方程更多的孤波解 。
Mixed exponential method proposed by Hereman for finding solitary wave solutions of a nonlinear evolution equation is presented. The method is developed and perfected according to the theory of mathematical mechanization, and with this method many solitary wave solutions not only of a nonlinear evolution equation(s) but also a multi-dimention equation can be obtained.
