文章根据层状介质中折射波的运动学规律,对多层结构中具有不同倾角界面折射波的运动学正反演问题从理论上进行了讨论,给出了多层倾斜界面结构中的折射波时距方程,以及利用相遇时距曲线资料计算界面产状及有关参数的递推公式和计算流程图.文章还对两种结构模型进行了、正反演计算,并取得了满意的结果.为利用微机对折射波资料进行解释提供了一种方法.

In accordance with the ground rules of kinematics of refraction in the multi-layered media, the forward and inverse problems concerning the kinematics of refractions in multi-layered medium with different angle were examined. The time-distance equation for multi-inclined interfaces, the recurrence formula and the flowchart for calculating the interface occurrence and their parameters (by using the time-distance curves with reciprocal time) were given. The forward and the inverse calculation for two kinds of these models were carried out and the positive results were obtained. A technique ofr the data interpretatinn by minicomputer was presented.
