Abstract

The nonlinear properties of ion acoustic shock waves in a magnetized electronegative plasma with nonextensive electrons and stationary dust grains are studied. The reductive perturbation technique is applied to derive the Zakharov–Kuznetsov Burgers (ZKB) equation. The Tanh method is used to obtain the shock wave solution. The present model is applied to four different electronegative plasma media which are found in space plasma, e.g. (H⁺, H⁻) plasma and (H⁺, O₂⁻) plasma, and laboratory experiments, e.g. (Xe⁺, SF₆⁻) plasma and (Ar⁺, O₂⁻) plasma. It is found that the concentration of negative ions and the electron nonextensive parameter have important effects on the features of the propagated ion acoustic shock waves.

摘要

研究了具有不扩散电子和固定尘埃的磁化负电等离子体中离子声波的非线性特性。还原摄动技术被用于推导Zakharov–Kuznetsov Burgers（ZKB）方程。Tanh方法用于获得冲击波解。本模型被施加到在空间等离子体，例如（H找到四个不同的带负电的等离子体媒体⁺，H ^- ）等离子体和（H ⁺，O- ₂ ^- ）等离子体，和实验室实验，例如（XE ⁺，SF ₆ ^-）等离子体和（AR ⁺，O- ₂ ^-）血浆。发现负离子的浓度和非电子扩展参数对传播的离子声波的特征有重要影响。
