摘要
During the seismic wave propagation process,as for the anisotropic lower medium,the speed is a function of the propagating direction.This article focuses on solving the problem how to get the transmittance angle and speed,knowing the upper seismic wave propagation velocity and the angle of incidence conditions.The main theories used Snell law,Christoffel equation and speed characteristics.Taking the HTI medium as an example,the authors give the detailed solving process and draw the space velocity characteristic curve.
