Abstract : based on recent english literature , this paper has summed up the present state and development of important gravimeters in the world , described a new type digital supergravimeter , and a new designing idea for gravimeter , viz . the application of absolute scale to the measurement of relative gravity 文摘:根据最近的英文文献，综述了世界上重力仪的现状及的发展，介绍了一种新型的数字式超级重力仪，以及重力仪的一个新的设计思想应用绝对标度测量相对重力。
Then , harmonic analysis is done with the newest baytap - g tidal data analyzing software developed by ishiguro and professor tamura , who are working in japan and the eterna34 tidal data analyzing software developed by wenzel , who had worked in german . as a result , the recently observed tidal gravity parameters of jiufeng station are obtained . finally , the ocean loading correction of the observing tidal gravimetric parameters , the temporal synthesized tide , correction of the station air pressure and the polar motion on the gravity residual , the analysis of the final residual , and so on , are investigated Vauterin研制的tsoft潮汐数据预处理软件，实施了观测数据的预处理，为超导重力仪观测数据的国际资料交换和数据分析准备了修正后数据；然后利用由日本ishiguro与tamura研制的最新的baytap - g和由德国的wenzel研制的eterna34潮汐分析软件，对预处理后的重力潮汐观测数据进行调和分析，获得了九峰台最近的观测重力潮汐参数；最后讨论了观测潮汐参数的海潮改正、随时间变化的重力合成潮的构制、大气效应改正、极移重力改正以及最终重力残差的分析。
