摘　　要：较系统地介绍了由比利时皇家天文台Vauterin博士研制的Tsoft重力潮汐数据预处理方法和由日本国立天文台Tamura博士研制的Baytap G潮汐数据分析方法。作为应用 ,利用武汉九峰动力大地测量学观测站超导重力仪 1999年观测数据 ,先实施预处理 ,再作数据分析 ,获得地球潮汐常数。数值结果说明 ,利用Tsoft方法可有效消除各种干扰信号 ,由BaytapA new approach Tsoft for tidal gravity data pre processing made by Dr. Vauterin with Royal Observatory of Belgium and a new method Baytap G for analyzing tidal gravity measurements by Dr. Tamura with National Astronomical Observatory, Japan, are introduced systematically in this paper. As an application example of these new approaches, using the data recorded with the superconducting gravimeter at Jiufeng Dynamic Geodesy Station in Wuhan in 1999, we do pre processing firstly and then analyze the pre processed data to acquire the earth's tidal parameters. The numerical results show that various kinds of interferences can be eliminated effectively by using Tsoft. The accuracy of the tidal parameters determined by Baytap G is similar to that by Eterna method, which is used popularly and internationally at present.
