庐山重力短基线场初值测定

利用FG5绝对重力仪对庐山基线场的3个基点和九江地震台的1个基准点进行绝对重力测定，使用7台CG-5相对重力仪对24个基点和1个基准点进行2个往返闭合测量。基于绝对重力控制解算的结果表明，基点点值精度均优于±5.0 μGal，相邻各段段差精度均优于±3.0 μGal。该基线场初值测定方法是一种崭新和现代的方法，具有科学意义和经济效益。

Determination of Gravity Values for Lushan Short Gravity Calibration Baseline

Using the FG5 absolute gravimeter, absolute gravity values are determined at three base gravity sites in Lushan and one datum site in Jiujiang seismic station to determine the Lushan calibration baseline.Further, twenty-five sites are determined using seven CG-5 relative gravimeters with two return measurements. The results show that the accuracy of gravity values at all of the base sites is better than ±5.0 μGal.The application of FG5 absolute gravimeter along with several relative gravimeters to construct short calibration baselines is a new and modern approach which has scientific significance as well as economic value.
