摘要

程函方程走时反演是一种用有限差分解程函方程计算地震波走时的正演过程, 与最优化技术相结合, 实现了自动修改模型参数、加快拟合速度。通过实例计算结果表明, 效果较好。

Abstract

The traveltime inversion using eikonal equation is a forward process which gets traveltimes by solving eikonal equation with finite differcnce method. Together with optimization techniques,the modificaion of model patameters and speeding up of fitting can be achieved. Computation with real data shows that a good result has been generated.
