| 摘 要： | 为提高天然地震折射与反射速度CT的精度,我们运用＂走时最小纵横波速度层析成像＂与＂波形基本解纵横波速度层析成像＂相结合的方法,反演各层界面形状及各层纵波、横波速度。反演结果图与＂正演地球模型剖面图＂基本一致。本文在数学上发展了＂层析成像＂的内容,提出＂波形基本解纵横波速度层析成像＂基本概念,是天然地震简单模型实验的初步...

| Abstract: | Base on the theory established in which deal with the man-made multilayer medium data,we apply it to the case of natural earthquake by using the principle of minimization of travel time and tomography of fundamental solution of wave equation to invert the interface shape and the velocity of P and S seismic wave’s velocity of each layer. |
