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。

Not only the influence of average normal anisotropy but also the one of planar anisotropy on the flanging height can be taken into account.

该模型不仅能够考虑板材的厚向各向异性特性，而且也能够考虑面内各向异性对翻边高度的影响。

The results show when formations contains a single vertical parallel fracture system, the amplitude of reflected P-wave is more sensitive than velocity for different infillings of vertical fractures; the anisotropy increases as fracture density increasing; the anisotropy of gas-bearing fracture is stronger than the fracture saturated with fluid.

研究结果表明，当地层中含有单组垂直的平行裂隙时，反射P波振幅对垂直裂隙中充填物的敏感性大于速度对裂隙中充填物的敏感性，随着裂隙密度的增加，P波各向异性程度也相应增强，裂隙中含气时，各向异性程度较含饱和水时强。

Next,by the use of the method on anisotropy subdivision in [8],we have proved the properly advanced element satisfy the feature of anisotropy for arbitrary convex cuboid subdivision in 3-dimension space and the error estimate is obtained.

Moreover, strong anisotropy is observed in the north and southcentral Tien Shan. Fast Pn velocity in the southcentral Tien Shan is nearly in NS directions, which is consistent with the SKS wave anisotropy concerning mantle flow. However, fast Pn velocity directions in the northcentral Tien Shan show a southward rotation variation. We estimate that it is probably related to the inserting of the crust of the Chu basin from the southern Kazakhstan platform to the central Tien Shan, which caused a change of stress fields and lithosphere deformation.

中天山北部和南部的各向异性也存在一定的差异，南部各向异性的快波方向为近南北方向，与SKS波的各向异性特征基本一致，反映了地幔物质的迁移方向；北部各向异性的快波方向呈向南凸出的旋转趋势，估计与哈萨克地台南缘楚河盆地地壳块体向天山挤入造成应力场的改变和岩石层变形有关。
