Compared with the seismic responses of free homogeneous half space, the results present the effect of vertical cracks on the propagation of seismic wave and the ground motion near the fault site.
计算结果与均匀半空间自由场做了对比，以说明竖向地裂缝对地震波传播和附近地面运动的影响。

In the end, the propagation of cylindrical wave in freespace, and the hollow cylinder scattering characteristics in near field and far field is completed when it is initiated by cylindrical wave.
最后，模拟了柱面波在自由空间中的传播及空心圆柱体在柱面波入射下的近场和远场散射特性。
