地球内部结构及物性研究的进展及问题

Study on the structure and physical properties of the earth′s interior

本文对近几年中国地球物理学家在地球内部结构和物质性质方面的研究工作进行总结.从地球内部结构的地震波速度成像,地幔介质的各向异性,地幔间断面及地幔介质物性进行了综述,指出在一些原有的研究领域,工作更加深入,方法更加先进,而且进行了广泛的国际合作,合作的范围也逐渐扩大,方式多样,并开拓了一些新的研究方向.在肯定我们近几年取得的一些新的进展的同时,也提出了地球内部结构研究中应进一步研究的问题.

The studies on the structure and physical properties of the earth＇s interior done by Chinese geophysicists in recent years are reviewed. It mainly contains the seismic velocity structure of the earth＇s interior, anisotropy of the mantle, mantle discontinuities and the physical properties of mantle. It can be found that new progress in the study on the structure and physical properties of earth＇s interior has been made in the recent years in China： In some preexistent areas much progress has been made, advanced methods have been adopted, extensive international co-operation has been conducted in many ways, the scope of the co-operation has gradually expanded, and some new fields appear as well. Moreover, problems in the study of structure of the earth＇s interior are also pointed out.
