论文摘要
研究了两倍无碰撞等离子体中脉冲的非线性动力学，并研究了分散性冲击波的形成。对在均匀密度背景下具有足够光滑密度曲线的任意形式进行了分析描述。在波浪破裂力矩分散冲击波之后的很长一段时间内。其边缘的运动是在Gurevich-Pitaevskii理论和调制理论的框架中研究的。将分析结果与数值溶液进行比较。
The nonlinear dynamics of pulses in a two-temperature collisionless plasma with formation of dispersion shock waves is studied. An analytical description is given for arbitrary form of an initial disturbance with smooth enough density profile on a uniform density background. For large time after the wave breaking moment dispersive shock waves are formed. Motion of their edges is studied in framework of Gurevich-Pitaevskii theory and Whitham theory of modulations. The analytical results are compared with numerical solution.
