| 摘 要： | 地球内部非弹性介质广泛存在,垂向线性连续变化非弹性介质模型具有重要理论与实际意义,本文利用复速度概念推导得到了复速度随深度线性连续变化的非弹性介质中地震波射线轨迹与等时线方程.理论结果表明:在线性连续变化非弹性介质中,射线轨迹呈圆形,等时面的形状为椭圆.最后对射线轨迹与等时线方程的适用性条件进行了讨论.

| Abstract: | The viscoelastic media exist videly in the earth. The model of vertical linear continuous varying vis-coelastic media is very important whether in seismic theory or application. In this paper, by using the definition of complex velocity, we have derived the ray paath and isotime equations in the viscoelastic media with vertical continuous varying complex velocity, the theory result shows that the ray path is as a circle,the isotime plane as an oval. Finally we discussed the condition of application of the ray path and isotime plane equations. |
