摘要:

综述了准垂直和严格垂直无碰撞激波的理论和模拟。正文分为以下几个部分和小节:1.设置的框架,准垂直冲击问题制定,反映粒子动力学的理论条款,脚的形成和脚离子加速讨论,和冲击电位的解释。2.冲击结构,3.离子动力学,描述其在冲击重整和各种离子激发不稳定性中的作用。4.电子动力学,描述电子不稳定性的脚; 5。平稳性问题,提出激波非平稳的理论原因,讨论非线性哨声介导的变率,双流和修正双流变率,二维波纹的形成,6。总结和结论:冲击破裂的可能性。

英文摘要:

The theory and simulations of quasi-perpendicular and strictly perpendicular collisionless shocks are reviewed. The text is structured into the following sections and subsections: 1. Setting the frame, where the quasi-perpendicular shock problem is formulated, reflected particle dynamics is described in theoretical terms, foot formation and foot ion acceleration discussed, and the shock potential explained. 2. Shock structure, 3. Ion dynamics, describing its role in shock reformation and the various ion-excited instabilities. 4. Electron dynamics, describing electron instabilities in the foot; 5. The problem of stationarity, posing the theoretical reasons for shocks being non-stationary, discussing nonlinear whistler mediated variability, two-stream and modified two-stream variability, formation of ripples in two-dimensions, 6. Summary and conclusions: The possibility of shock breaking.
