摘要
从ＨａｓｅｇａｗａＭｉｍａ方程出发，对非线性漂移波进行解析和数值研究．数值结果表明，等离子体中静电波的初始扰动，由于非线性模耦合而发生演化，形成链状局域结构，并通过相互吞并。
Abstract In this paper,the nonlinear drift waves described by the Hasegawa Mima equation have been investigated by means of analytic researches and numerical simulations.The numerical results have been shown by figures.The initial disturbances of electrostatic waves,by the nonlinear mode coupling,will evolve into a chain of vortices,these vortices gobble up each other and some large stable vortices are formed at the final stage of the nonlinear evolution.
