对利用数字地震波形资料探测上地幔深部间断面的研究进行了综述,并特别对利用宽频带资料的研究结果进行了介绍。在对80年代以来的研究状况进行概述的基础上,对目前存在的困难进行了分析。

Since 1980's, there have been much progress on study of transition zone in upper mantle, in detection of both physical and chemical feature. Summarizing on study of transition zone in upper mantle using digital seismic data is given, and state of study using broadband seismic data is introduced. Up to now, there are still different views on feature of transition zone in upper mantle, especially for 670 km transition zone. On the basis of comment on researches after 1980's, this paper analyses the existing problem in the present and indicates possible direction of study.
