本文提出了一种新的用于计算波速层析成像理论走时的射线追踪算法，并通过数值计算对该算法进行了评价。该算法通过设置中继点来减少光线跟踪结果对网格的依赖性，从而减少了光线路径估计的不准确性。中继点应均匀地安装在网格上，以使射线路径在横截面上均匀分布。结果表明，新算法在射线路径表示上有了明显的改进。(C)2013爱思唯尔有限公司保留所有权利。
A new ray-trace algorithm, that is used for calculation of the theoretical travel time, is introduced for wave velocity tomography, and it is evaluated by numerical investigations in this paper. Relay points are installed for reducing the mesh dependency of results of the ray-trace that causes inaccurate estimation of the ray-path in the presented algorithm. The relay points are intended to be installed on the mesh uniformly for uniform distribution of the ray-path on the cross section. The comparison of the results from the new and conventional algorithm showed improvement in the ray-path representation of the presented algorithm. (C) 2013 Elsevier Ltd. All rights reserved.
