摘要
本文简要介绍了北京和南宁两个国际绝对重力基本网(IAGBN)点的点位和环境条件,列出了这些点上的首批绝对重力测量结果及所使用的仪器。在北京点的测量结果表明,不同仪器的测量结果间差异很小。将IAGBN点的1990年观测值通过换算后求得了同一城市的我国1985重力基本网(85网)点的重力值,与1981年意大利绝对重力仪IMGC的测量结果和85网的平差值作了比较。
:A general deseription of the locations and environmental conditions at twoIAGBN stations in China, Beijing and Nanning, is given. Also presented arethe first results of absolute gravity measurement at these stations and theinstruments used. These results indicate that good agreement exists among theresults obtained by different gravimeters at Beijing station. The gravityvalues at China Gravity Basic Net-85 (CGBN-85) stations obtained bytransforming the observation values in 1990 at IAGBN station in the same cityhave been eompared with the results determined by Italian gravimeter IMGCin 1981 and the adjusted values of CGBN-85 respectively.
