应用混合模拟方法数值研究了高Ａｌｆｖｅｎ—Ｍａｃｈ数垂直无碰撞激波与等离子体间的相互作用。结果表明，激波上游的磁场非常稳定，粒子分布近似为Ｍａｘｗｅｌｌ分布。激波下游磁场存在不规则的湍动，质子分布有一个高能尾，且有些质子被激波反射。跟踪少量高速质子的计算结果表明，在ｔ＝４０Ω时约有４０％的质于被激波反射，而７％质子可被加速，最大速度值可达到２０ＶＡ激波区的电场分布对质子的减速或加速起了主要的作用。 The interaction between high-Alfven-Mach number vertical collisionless shock waves and plasma is studied numerically using a hybrid simulation method. The results show that the magnetic field upstream of the shock wave is very stable and the particle distribution approximates the Maxwell distribution. There is irregular turbulence in the magnetic field downstream of the shock wave. The proton distribution has a high-energy tail, and some protons are reflected by shock waves. The calculation of a small number of high-speed protons followed showed that about 40% of the masses were reflected by the shock at t = 40Ω and 7% of the protons could be accelerated with the maximum velocity reaching 20VA. Or speed up played a major role.
