| 摘 要： | 本文给出了中科院测地所FG5-112和日本京都大学FG5-201及日本国土地理院FG5-104等几台绝对重力仪在武汉九峰和香港天文台绝对重力测量比对结果。分析说明不同仪器间具有良好的一致性,其中FG5-112与FG5-104结果间的互差达8×10-8m/s2;FG5-112与FG5-201和FG5-104等的观测互差小于2×10-8m/s2。这种比对观测,可为深入了解仪器性能和精确测定不同台站重力非潮汐变化提供可靠参考。

| Abstract: | The Comparison of the Absolute Gravity Measurements Obtained with China and Japan Instruments at stations of JiuFeng/Wuhan and HongKong Observatory are given by using the FG5-112 of Institute of Geodesy and Geophysics,Chinese Academy of Sciences,FG5-201 of Kyoto University and FG5-104 of Japan Institute of Geography.The analysis shows that there exists a good agreement among the various absolute gravity instruments.Among them,the discrepancy of the results obtained when using FG5-112 and when using FG5-104 is given as of 8.0×10~(-8)m/s~(2);and that when using FG5-112 and FG5-201 and FG5-104 is less than 2.0×10~(-8)m/s~(2).It is showing that such kind of comparison can provide the variable reference in understanding the characteristics of the instruments and in determining accurately the non-tidal variations at various stations. |
