We summarize and explain the treatment to the permanent tide in the reduction of gravity data.
同时对重力数据归算中的永久性潮汐的处理进行总结和说明。
In this paper, it is pointed out theoretically that the ground surface tilt is not observed by only tiltmeter, but must be determined by both tilt and gravity earth tide data.
本文从理论上阐述了单靠倾斜仪不能监测地面倾斜，必须联合倾斜和重力固体潮资料才能测量地面倾斜。
Using TOPEX altimeter data, a few new earth gravity models, geoid models and ocean tide models were generated, and these models were better than old models.
利用TOPEX资料可以得到新的地球引力场、海洋大地水准面和海潮模型。
