摘要
地震波散射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深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。这里从地震波散射的理论和方法研究二个方面,对地震波散射研究的进展作评述。首先回顾了地震波散射的基本概念、研究历程及研究的各个方面,对散射理论进行了系统评述,同时对先辈们关于散射波数值模拟的情况进行了总结。
The investigations of seismic wave scattering is an important research field in geophysics, their progresses are of great significance for us to cognize and realize the structure and physical characteristics of the earth's interior. At the same time, it is the great impetus to the research of geodynamics. In this paper we give out the remarks to the progress of the seismic wave scattering from the view of theory and method. We first review the basic concept, the development history and the mainly researching aspects of the seismic wave scattering theory and then give out our comments to the seismic wave scattering systematically. In the paper, we summarize the actuality of the numerical modeling of the seismic wave scattering. At last, we indicate the development direction of seismic wave scattering and the corresponding numerical modeling.
