We have investigated the transportation and circulation of materials in global earth from the surface to the core of the Earth by using the high pressure techniques. We have established four research groups, A01-A04, and have promoted the research on the interaction of the subducting slabs with the mantle and core. We have made the meetings of the steering members of this project six times, and circulated newsletters (no.1〜no.18). We also made seven domestic research symposia and one international workshop, which is co-sponsored by COMPRES and BGI. The meeting was held in 2002 in Barbania, Italy. These activities made it possible to achieve the high productivity of this research area.

利用高压技术研究了全球地球物质从地表到地心的输送和循环，成立了A01-A04四个研究组，推进了俯冲作用的研究。我们已经举办了六次该项目的指导成员会议，并回收了通讯（第1~18期）。我们还举办了7次国内研究研讨会和1次国际研讨会。 - 赞助者COMPRES 和 BGI 于 2002 年在意大利巴尔巴尼亚举行了这些活动，使得该研究领域的高生产力成为可能。
