非纵观测系统地震测深资料分析处理的人机对话过程

本文在三维壳幔结构中两点射线追踪分步搜索算法的基础上，在物探中心地震方法研究室ＳＵＮ工作站上研究开发出可应用于非纵观测系统深地震测深资料人机对话三维分析处理的方法及软件。对研究区域的三角形剖分减少了人机对话过程中的工作量及人为干预，并用该方法以反演得到的华北块状模型作为初始模型，对该模型的剩余ＰｍＰ波残差进行了人机对话拟合。

MAN-COMPUTER COMB-TION FOR INTERPRETATION OF SPATIAL DEEP SEISMIC SOUND-DATA

Based on the Indirect--approach Method for specified--ends seismiotray tracing inthree--dimensional inhomogeneous media, we developed a new technique along with itsFortran 77 programs that can be applied to interpretate the spatial deep Seismic soundingdata at Sun Work Saution, Department of Seismology, Research Center of ExplorationGeophysics. In the process of travel time data fitting and model parameter estimations,according to priori information about geological structures, we devide the investigated region into triangular cells so as to reduce man--made effeCt on the Fmal model and saveworking hours. Using a reference model obtained from PmP travel time inversion as an initial model, we applied this technique to fit a PmP travel time data set from North China,and thes method considerably decreased the remnant residual from the reference model.
