本文介绍了陕西天文台守时用氢原子钟(H2)的改进、分项误差、准确度及在国际时间局(BIPM)公报中取权情况.H2自1991年开始连续运转至今已两年多了。1991年3月开始每月向BIPM报送数据,1991年9月开始取权1.H2是我国唯一的一台在BIPM公报上取权的氢钟.
n this paper,improvement for the hydrogen maser(H2)are described.Various errors in hydrogen maser,its accuracy and weights reported by BIPM are also introduced.H2 has been put into regular opration since 1991, its results have been sent to BIPM monthly since march. 19gi.and it got the weight of 1 from BIPM in septemper of that year, the weight has increased to 10 by now.
