中文摘要：
利用一维全粒子模拟得到的垂直无碰撞激波的位形，通过试验粒子方法研究了不同初始能量粒子的激波加速机制．将与激波相互作用的离子分成反射和直接穿过两类，发现只有被激波反射的离子可被激波明显加速，其中初始能量较小的反射离子通过激波冲浪机制加速，而初始能量较大的离子通过激波漂移加速机制加速．同时激波厚度还对离子被加速过程有重要影响．
英文摘要：
With one-dimensional （1D） perpendicular eollisionless shocks obtained by full particle two groups at the shock front, the reflected ions and the directly transmitted ions. Only the reflected ions can be accelerated significantly. Moreover,the lower initial energy ions are accelerated by shock surfing mechanism,and the higher initial energy ions gain energy by shock drift acceleration. Meanwhile, the thickness of the shock can significantly affect the acceleration process of ions.
