| 摘 要： | 利用地震记录反演震源非均匀特征是目前强震地震学研究中的一个重要的课题。本文在总结现有文献的基础上，对与震源反演相关联的六个环节即震源模型及模型参数、格林函数计算、观测数据、反演准则与目标函数、初始模型与迭代方式、反演精度与分辨率等进行了初步阐述和分析，同时对地震源反演中存在的问题也进行了相应的讨论。

| Abstract: | The inversion of heterogeneous characteristics of seismic source is an important field in strong earthquake seismology at present.This paper is focused on illustrating and analyzing six interrelating steps of inversing seismic source processes by using seismic records,which are as follows:(1)seismic source model and model parameters;(2)calculation of Green function;(3)observation data;(4)inversion criteria and objective function;(5)initial model and iterative procedure;(6)inversion precision and resolution.Some problems in inversion of seismic source are also correspondingly discussed in detail. |
