摘要
地震波场正演模拟、层析成像、偏移成像经常需要用到射线追踪，本文在基于图形理论的Ｍｏｓｅｒ法基础上，改进其网格节点的划分、追踪时路径的选取，并增加直射线追踪以消除在速度变化不大时射线受节点布置影响出现不合理的折曲现象．
Seismic wavefield modeling,tomograph,migration are closely related to ray tracing. In this paper,we improve Mosers shortest ray trace method based on network theory,on arranging nodes and on picking path in tracing. Also we add straight ray trace to eliminate irregular inflexion because of sparse nodes arrangement
