摘要
运用约化摄动方法,研究了在高阶横向扰动下,具有两种温度离子的磁化尘埃等离子体中的尘埃声孤波,得到了描述尘埃等离子体中小振幅尘埃声孤波的ZK方程,讨论了横向扰动对孤波振幅和宽度的影响,并分析了存在压缩型孤波和稀疏型孤波的条件.
By using the reductive perturbation technique,we derived a ZK equation for small amplitude dust -acoustic waves. The transverse perturbation has significant effects on the solitary wave amplitude and width. It has been found that there may exist both rarefactive solitary waves and compressive solitary waves in this dusty plasma.
