摘要
根据Snell定律提出了透射射线的非线性效应的概念,从理论上证明了当地震射线的轨迹在1个界面上为1条直线时在另1个界面上可为1条曲线;并进一步通过射线追踪实验证明:当地下介质为非水平层状介质时,即使对应于地面同一条直线段上的接收点,来自地下同一个界面上的反射点的轨迹仍可为一条曲线。
The nonlinear effect of transmitted rays is presented based on Snell'slaw.It is theoretically proved that when a seismic ray trajectory is a straight line on an interface it may be a curve on another interface. It is further demonstrated experimentally that when the media are not horizontal layers the reflection point trajectory from the same interface can be a curve even corresponding to a straight receiving segment on the earth surface.
