2 ) the effects on waves conversion are stronger in rocks with dry fractures than that in rocks with water - filled fractures , and s - waves attenuate more rapidly in rocks with water - filled fractures . 3 ) the explosive point source which locates in anisotropic media can excites not only p - waves but also s - waves . 4 ) the properties of waves propagation were discussed and compared for several point sources with different source functions 结果表明： 1 )平行排列裂缝造成的各向异性使波前变宽； 2 )含干裂缝岩石对波型转化的影响比含充水裂缝岩石的大，横波在含充水裂纹中传播时衰减较快； 3 )当介质存在各向异性时，爆炸点源产生的波不仅有纵波，还有横波； 4 )通过改变点源函数研究不同点源所产生波以及波型的转换。
Ava analysis plays an important role in the multiwave seismic data processing . the anisotropy , however , has an important influence on the ava . therefore , the multiwave amplitude characteristic equation of the anisotropic media should be established and then the ava analysis and parameter inversion could be realized Ava ( amplitudeversusangle -振幅随入射角变化)分析在多波资料处理中有着重要的作用，然而介质各向异性对ava有着重要的影响，因此需要建立各向异性介质中的多波振幅特征方程，以利于多波资料进行ava分析和地层参数反演。
The psm was extended to heterogeneous anisotropic medium and a program for 2d elastic waves propagation was written in fortran . the stable condition of psm for 2d anisotropic media was introduced and discussed . the propagations of elastic waves , excited by point sources in homogeneous isotropic / anisotropic rocks , were simulated 导出了适用于模拟二维各向异性非均匀岩石中弹性波传播、以位移为变量的伪谱法公式并编写了相应的程序，并推导了适用于二维各向异性介质的伪谱法稳定性条件。
The gauss - ray tracing have the dynamic and geometric character . it can compose the record by calculating the high frequency wave in transverse anisotropic medium , avoiding getting the accurate ray path . it is a very steady and effective method with little calculation time and a good precision 高斯射线束正演包括地震波运动学特征和动力学特征，能有效的计算横向上不均匀介质中高频体波的合成纪录，避开了精确求取两点射线路径，大大减少了计算的时间，同时又具有较高的精度，是一个很稳健有效的方法。
