中文说明：应用背景 相应的射线追踪代码，主要通过考虑各种折射条件，求解地震方程从而确定地震波源所在的位置。代码主要分为5个部分，运行代码是需要调用各个文件中的函数，压缩文件中有相应的说明文档。 关键技术 用于确定地震源的射线追踪代码，考虑到实际的电离层参数，以及由地震激发的波的传播速度求解相应的方程可以初步确定地震波的传播路径。
English Description：
Application backgroundCorresponding ray tracing code, mainly by considering various refractive conditions, solving the equation of earthquake to determine the position where the source of seismic wave. Code is mainly divided into 5 parts, the code is required to call the function of the various documents, compressed file in a corresponding description document.Key TechnologyUsed to determine the source seismic ray tracing code, taking into account the actual ionospheric parameters, and excited by earthquake wave propagation speed of solving the corresponding equations can preliminary determine the path of propagation of seismic wave.
