用FORTRAN编制的交错网格化数值模拟程序，生成共炮点理论地震记录。-using FORTRAN compiled by the staggered grid of numerical simulation program to produce a total theoretical shot seismic record.

地震正演程序，在已有的数值地质模块基础上采用正演模拟公式来对地震波在地下的传播进行模拟，相对描述出地下地层岩性情况。-Seismic forward procedure, the values have been adopted on the basis of geological block formula for forward modeling of seismic wave propagation simulation in the ground, and the relative d

该代码主要是讲解射线追踪方法在地震正演中的应用，可以较好的用于实际地震数值模拟当作，本人写了好久可以当作学习材料的-The code is mainly to explain the ray tracing method in seismic forward in the application, can be better used as a numerical simulation of the actual earthquake, I wrote a long time can be us

弹性波数值模拟，可以修改模型，可以做波场模拟，做面波的地震记录((Numerical simulation of seismic surface waves, you can modify the model, you can do the wave field snapshots do surface wave seismograms))
