摘要
地震波非线性反演方法研究跟正演模拟方法研究一样,是地球物理学中一个非常重要的研究领域,其进展对人们正确认识和了解地球内部的细节及物性具有重大意义,对地球动力学的研究也具有不可忽视的推动作用。对地震波非线性反演问题理论研究的进展作了评述;在简单回顾非线性反演方法发展历史的基础上,总结了近年来常见的非线性反演方法研究的最新进展情况,对非线性反演中存在的各种问题进行了比较和评述,同时指出了目前非线性反演方法存在的问题,并对今后发展的方向作了简要展望。
In this paper, the author firstly provides a brief review of the progress of theory wave--field inversion from two aspects, namely, theory and method of the nonlinear inversion problem. On the bases of a brief historical retrospect of the nonlinear inversion problem. On the basis of a brief historical retrospect of the nonlinear inversion method in recent years, the author concludes the newest advances in the familiar nonlinear inversion method research, makes some comparisons and comments on some problems consisting in the nonlinear inversion method, at the same time points out some problems existing in the nonlinear inversion method at present, and at the end gives some expectations for new advancing direction of the nonlinear inversion theory.
