摘要
利用四面体单元模型讨论了地震波在三维横向不均匀介质中的传播路径和走时的计算方法 ,给出震源所在四面体的确定方法。以华北地区大地构造模型为例 ,计算了直达波走时曲线 。
The seismic ray path and the calculating method of travel time in 3 D transverse inhomogeneous medium has be discussed with finite tetrahedral model The way to determinate the source tetrahedron is given The North China's travel time has calculated, the result is satisfied
