【摘要】 反射波走时和梯度是反演的基本数据,从地震资料上拾取这些数据是层析成像的关键问题。文章推导和研究各参数对拾取结果的影响,最后通过实验得到拾取结果的最佳参数组,从而发现参数选取的一般规律。更多还原

【Abstract】 Travel time and gradient are basic data of inversion,picking up them from seismic data is the key issue in tomography.Various parameters which effect picking up results are derived and researched in this paper.Best parameters are obtained after carrying out experiments and general regularities of selecting parameters are also found.更多还原
