多组分复杂等离子体中(3+1)维非线性离子声孤波的研究
The study of (3+1) -dimensional nonlinear ion acoustic solitary waves in multi-component plasma
摘要
Abstract
In this paper, the basic propagating characteristics of (3+1) -dimensional nonlinear ion acoustic solitary waves in a multi-component complex plasma have been studied.The (3+1) -dimensional ZK equation for nonlinear ion acoustic solitary waves in a multi-component complex plasma system has been obtained by using the reductive perturbation method.Moreover, the important influence of different parameters on the nonlinear strength, amplitude, width and propagation characteristics of nonlinear ion acoustic solitary waves are also discussed by the numerical simulation method.关键词
