【摘要】 提出了一种基于形变映射理论的构造非线性方程行波解的方法 ,并用该方法求得了非线性Kdv Burgers方程和耦合Schr ding KdV方程的行波解。这种方法不仅找到了先前用其他复杂方法求得的若干精确解 ,而且在有的情况下还可找到新的解或更为一般形式的精确解。更多还原

【Abstract】 In this work, a new approach to nonlinear physical system mainly based on the de formation mapping theory is proposed and successfully applied to some classical physical models such as KdV-Burgers model and Schrding-KdV model. Not only a re the previously known solutions obtained by more sophisticated method recovere d, but also in some cases new solutions or more general forms of solutions are d erived.更多还原
