The quasi-perpendicular collisionless shock consists of foot, ramp and a series of overshoots and undershoots, after travelling back upstream for a short distance, the reflected protons gyrate back into the downstream where an temperature anisotropy is formed due to an anisotropy of velocity distribution, then excite Alfvén ion cyclotron waves and mirror waves that dissipate the kinetic energy into heat; At quasi-parallel collisionless shocks, the reflected protons can travel far upstream, and lead to the generation of ion beam instabilities which excite large-amplitude right-hand polarized ultralow-frequency resonant waves whose frequencies are are about〓 These waves are convected back downstream by solar wind and gradually merge to form the downstream state, in the meantime new waves are generated continuously in the upstream, this process where ULF waves are generated and merge into downstream state is cyclical.

准垂直无碰撞激波系由根部、斜坡区以及一系列的低冲和过插组成，被激波反射的质子向激波上游运动很短的距离就在回旋作用下再次向下游运动，和激波发生相互作用以后进入激波的下游，在激波的下游引起质子速度分布的各向异性，进而引起激波下游温度的各向异性，激发起Alfvén离子回旋波和镜波，将激波上游的动能耗散成激波下游的热能；在准平行无碰撞激波(θ〓＝10°)情况下，这部分质子能向激波上游运动很大一段距离，并在激波的上游激发起束流不稳定性，引起大振幅的低频波动。
