摘要

为标定FG5绝对重力仪及检测其性能,于2008年1月在中国地震局地震研究所的3053测点进行了绝对重力测量比对。研究表明,绝对重力仪FG5-214与FG5-232具有较好的一致性,二者几乎不存在系统误差;两台仪器都具有较强的抗干扰能力,重复性很好,内符合测量精度达(2～3)×10-8ms-2。
To calibrate absolute gravimeter of type FG5 and test its performance,a comparative experiment had been carried out at point 3053 of Institute of Seismology,CEA in 2008.1.The experiment shows that there is no obvious system error between FG5-214 and FG5-232.Both FG5-214 and FG5-232 have the strong ability of anti-jamming and repetitiveness,their inner coincidence accuracy are about(2~3)×10-8ms-2.
