首先必须设计和布置测网，选择一个测量基点，而这些测网交点便是重力测量的观察点。

First of all, You have to design the gravimetric network and a base stATion. Gravimeter observATion are usually made AT the corner of the square grid.

地形的起伏以及测点位置的准确性是否会影响重力测量的结果？

Do the topographical relief and the precision of the location of stations affect the result of gravimetric rneasurement?
