THE PROGRESS OF ASTROMETRIC RESEARCH WORK IN THE WORLD IN THE RECENT THREE YEARS

本文简述近三年来国际上天体测量的研究进展 ,特别是依巴谷星表向暗星扩充、2 0世纪初照相观测改进自行的精度和巡天观测资料对特殊天体物理现象的检测等方面的研究动态。最后介绍了空间天体测量卫星DIVA、GAIA、SIM和FAME计划的进展。

In this paper the progress of astrometric research work in the recent three years is briefly described, especially to study the extension of the Hipparcos catalogue to faint stars, the improvement of accuracy for proper motions with photographic plates at the beginning of 20 century and the detection of interesting astrophysical phenomena. Finally, the progress of space astrometric satellites:DIVA, GAIA, SIM and FAME are introduced.
