任意尘埃大小分布对非磁化尘埃等离子体中包络孤波的影响
Effects of arbitrary dust size distributionon envelope solitary wave in unmagnetized dusty plasma
摘要
Abstract
The nonlinear envelope solitary wave in unmagnetized dusty plasma with arbitrary dust size distribution,Boltzmann distributed ions and electrons is investigated.A (1+1)-dimensional nonlinear Schr(o)dinger equation through the reductive perturbation technique is obtained.After that the influence of arbitrary dust size distribution on nonlinear dispersion relation and group velocity are analyzed by the numerical simulation method.Moreover,the variations of the amplitude and width of envelope solitary wave are studied as well.关键词
