移动星团视差研究方法的改进

Progress in the Studies on Moving Cluster Parallax

因此，在大约一个世纪的时间内，确定移动星团视差的方法一直处于不断改进之中。

Various models and improvements on determination of moving cluster parallax have been made in the last century .

移动星团视差的精确测定对于宇宙距离尺度以及许多天体物理关系的研究起重要的定标作用。

The precise determination of moving cluster parallaxes plays an important role in the calibration of cosmic distance scale as well as many other astrophysical relations .

天文学家于1980年用数字和图形表示出昴宿星团正通过一气体云移动另外不与星团星星联系。

Astronomers figured out in the1980s that the Pleiades cluster was moving through a cloud of gas otherwise not associated with the cluster 's stars .
