【摘要】 研究了KdV-mKdV方程的行波解求解的问题,利用双曲函数法和新的G展开法,获得了该方程的含有多个任意参数的新的行波解,分别为三角函数解、双曲函数解、有理函数解和指数函数解,扩大了该类方程的解的范围。更多还原

【Abstract】 By using new G-expansion method with the aid of computer symbolic system,some new travelling wave solutions which involve parameters are obtained.These solutions contain the hyperbolic function solutions,the trigonometric function solutions,the rational function solutions and the exponential function solutions.The solutions of KdV-mKdV equation have been enriched.更多还原
