（2＋1）维ZK方程的孤立波解和周期波解

摘要

对（2＋1）维ZK方程进行了动力学定性分析，应用椭圆方程映射法和Jacobi椭圆函数展开法求得了方程的孤立波解、周期波解。%We made a qualitative dynamic analysis of the (2+1)-dimensional ZK equation .The elliptic equation mapping method and Jacobi elliptic function expansion method were applied to construct the soli -tary wave and periodic wave solutions to this equation .
