摘要
本文介绍的方法,对时间场法求取等时线方法进行了改进。经过理论推导,建立了便于数值计算的计算模型,并根据这一计算模型编制了FORTRAN—77计算程序。该程序不仅适用于均匀介质的情况,对地震波速度随深度变化的纵向不均匀介质等情况均适用。
The method introduced in this paper improves the contour way which is gained from time field. A computing model for the convenience of numerical evaluation has been established based on theoretical derivation. According to the computing model, a computer program is worked out by using Fortran—77. The program is suitable not only for homogeneous medium, and also for inhomogeneous one in vertical, which leads to change of seismic wave velocity in depth.
