| 摘 要： | 基于连续地球模型的ＢＧ理论，系统地研究了地球物理反问题，描述了地球物理反问题高度的非唯一性，给出了构造和评价解估计的一系列准则和方法。根据ＢＧ方法的一般原理，针对地震勘探等一类具体问题，利用地震走时，实现了地震波速度重建。

| Abstract: | On the basis of Backus-Gilbort theory of continuous earth model,theauthors systematically studied the peophysical inverse problems ,with emphasizins theheisht nonuniqueness of inversion,and provided a series of criteria and methods forsolution estimation construction and evaluation.This paper realized the seismic velocityreconstruction through usingthe travel-time,and the general principle of BG method. Compared with some present methods of seismic tomography,this method has manyvirtues,such as algorithms stability and higher resolution.The tomogrnphic resutts dueto this method are ideal. |
