摘要
对 1999~ 2 0 0 2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了总结 .分别对地球内部结构的地震波速度成像研究 ,中国及其周边地区上地幔介质各向异性的研究 ,S波介质品质因子Qβ,俯冲带研究 ,地幔间断面的研究 ,地球物质性质的实验研究以及其它方面的一些研究工作进行了综述 .指出了各方面的主要研究内容、使用的主要方法和得到的结果 .从这 4年的研究中可以发现 ,中国的科学家在地球内部结构和物质性质的研究中又取得了新的进展 ,主要表现在 3个方面 :一些原有领域中的研究更加深入 ;开辟了新的方向 ;研究方法更先进
The studies on the structure and physical properties of the Earth's interior done by Chinese geophysicists from 1999 to 2002 were reviewed in this paper. It includes several research areas: the structure of the Earth′s interiors using seismic tomography, anisotropy of the upper mantle in China and its adjacent areas, quality factor Q β for S waves, subduction zone, mantle discontinuities, physical properties of Earth′s materials and others. The review concerns mainly the contents, the methods and the results of the studies. It can be seen that new progress in the study on the structure and physical properties of the Earth′s interior has been made since the last 4 years in China. It is shown on three aspects: advancement made on some preexistent areas; pioneering on some new fields and new methods adopted.
