摘要
首先讨论如何改进最佳(短)路径算法实现快速射线追踪,然后论述弯曲射线地震波透射层析成像(cT)实现方法.数学模型的正反演计算以及实测资料的具体应用均证实这种方法与直线CT相比具有较高的成像精度和收敛速度,是一种较理想的成像方法.
In this paper,The shortest path algorithm is improved and the application to seismic rays tracing is introduced,Then a method of computing tomography using crooked seismic rays is emphatically discussed.The accuracy of the method is tested and verified by mathematical models and observed data.
