摘要/Abstract

摘要： 应用改进的简单方程法求得(2+1)维ZK-MEW方程的精确解，这些解包括双曲函数解、三角函数解。当对双曲函数解中的参数取特殊值时，可以得到了孤立波解。当对三角函数解中的参数取特殊值时，可以得到对应的周期波函数解。实践证明，简单方程法对于研究光电子学、量子光学、激光物理和等离子体物理具有非常广泛的应用意义。

Abstract: Exact solution for the (2+1) - dimensional ZK-MEW equation is obtained by using the improved simple equation method. These solutions include hyperbolic function solutions, trigonometric function solutions. When the arbitrary parameters in hyperbolic function solutions are taken as some special values, the solitary wave solutions can be obtained.When the arbitrary parameters in trigonometric function solutions are taken as some special values, the trigonometric function solutions can be expressed as periodic wave solutions. Experience has proved that Simple equation method has a very wide range of application in the study of optoelectronics，quantum optics , laser physics and plasma physics.
