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。
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.
利用所建立的模型，将航空重力测量试验数据采用最小二乘配置的方法向下延拓到地面，与地面已知重力数据进行比较。
Using this model, the airborne gravity measurement test data is downward continued based on least squares collocation and is compared with known ground gravity data.
讨论了应用GPS测量重力点的大地高，从而获得地面点的扰动重力（或称纯重力异常）值这样新的重力边值条件，如何从理论与实际上确定重力场的问题。
This paper discusses the problem of gravity field determination by application of such a new gravity boundary condition as the disturbing gravity by use of GPS.
