摘要: 2004~2005年南极夏季期间,我国第21次南极科学考察队利用FG5绝对重力仪在长城站两个站点(C001和C002)进行了绝对重力测量,精度在±3×10-8ms-2以内,并同时进行了重力垂直梯度测量和水平梯度测量;利用2台LCR相对重力仪在韩国站、智利机场(2点)和菲尔德斯半岛地区的山海关、盘龙山、香蕉山、半边山等7个站点进行了高精度相对重力测量,精度达±10×10-8ms-2,并进行了相对重力仪比例因子的标定,建立了我国南极长城站地区绝对重力基准。

Abstract: During the 2004-2005 austral summer season,the 21st Chinese National Antarctica Research Expedition(CHINARE) carried out the absolute gravity measurement using FG5 absolute gravimeter at Great Wall Station,West Antarctica,the precision is within ±3 ×10-8 ms-2,at the same time,the vertical and horizontal gradient of gravity were measured.The relative gravity measurements were carried out using LaCoaste & Romberg(LCR) superconducting gravimeters at 7 sites in the Great Wall station area,the precision is within ±10 ×10-8 ms-2,and the scale factor was precisely determined.
