摘要

从理论上研究了小而有限振幅的尘埃声孤波在磁化无碰撞尘埃等离子体中的非线性传播。假设电子被困在旋涡状分布中,带负电荷和正电荷的离子随着电荷波动的静止尘埃的存在而移动,其中离子质量提供惯性,热电子的热压提供恢复力。采用约简摄动法得到了一阶势的修正Korteweg-de Vries (mK-dV)方程,并得到了平稳解。讨论了捕获电子、带正电荷和带负电荷的离子以及任意带电尘粒的存在的影响。

The effects of vortex like distributed electron in magnetized multi-ion dusty plasmas
The nonlinear propagation of small but finite amplitude dust-ion-acoustic solitary waves in a magnetized, collisionless dusty plasma is investigated theoretically. It has been assumed that the electrons are trapped following the vortex-like distribution and that the negatively and positively charged ions are mobile with the presence of charge fluctuating stationary dusts, where ions mass provide the inertia and restoring forces are provided by the thermal pressure of hot electrons. A reductive perturbation method was employed to obtain a modified Korteweg-de Vries (mK-dV) equation for the first-order potential and a stationary solution is obtained. The effect of the presence of trapped electrons, negatively and positively charged ions and arbitrary charged dust grains are discussed.
