The probes have been measuring subtle variations in the Moon's gravity field.

这两辆探测仪在月球重力环境中发生了微妙变化。

Studies of the gravity field of the Earth indicate that its crust and mantle yield when unusual weight is placed on them.

对地球引力的研究表明 在不寻常的负荷之下地壳和地幔会发生位移。

And since this is all an exponent, it means that if we increase the strength of the gravity field we're in, this number goes up really quickly.

因为这都是指数， 这意味着如果我们增加我们所处的重力场的强度，这个数字就会上升得非常快。
