和别的卫星不同，它没有可能干扰重力测量的常规活动部件。

Unlike other satellites, it has none of the usual moving parts that could interfere with the gravity measurements.

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?

You know, if you want to measure the potential energy of something in a gravitational field, you have to define the zero somewhere, right, because it's arbitrary. You can set it anywhere you want. It's the same with enthalpy.

你知道，如果你想测量重力场,中某种东西的势能，你需要，在某处定义一个零点，对吧？,因为势能的值是任意的,你可以把它设定在。
