分别用扩展的双曲函数法,指数函数法和吴消元法,得到了GKP方程的多个新的显式解,这些解包括孤波解,奇性孤波解;并用CK直接约化方法求得两组关于GKP方程新旧解之间的关系,从而可以得到GKP方程更多的精确解.
We obtain some solutions of GKP equation which contain soliton wave solution and singular soliton solutions by using hyperbolic function and exp-function method and the relationship between the new solutions and the old ones by using direct method.
