摘要：

１９９１年１２月乘“极地号”科学考察船使用ＬａｃｏｓｔｅＧ型重力仪从澳大利亚塔斯马尼亚大学一国际重力点［ＩＧＳＮ７１］联测至中山站，两点间重力差达２１５４ｍｇａｌ，测得中山站重力基础点值为９８２５７１．３４８±０．１５ｍｇａｌ。

Abstract:

In the December of 1991, the connection measurement from international gravity point(IGSN71)-Tasmania University to Zhongshan Station was carried out making use of Lacoste G gravimeter by "JIDI" scientific investigation ship. The gravity difference between both points reaches 2154mgal, and finally the gravity base point value obtained at Zhongshan station is 982571.348±0.15mgal.
