地球重力场 earth gravitational field
- 高阶高精度地球重力场模型具有广泛的用途。
High order, high precision geopotential models have broad application. - 我们注意到,这个问题同在地球重力场中水平抛射一个球体十分相象。
We've noted that this is just like a body projected horizontally in the earth's gravitational field . - 随着重力卫星计划的实施,地球重力场的研究也将因此产生质的变化。
Along with the implementation of gravity satellite plans, therefore, research on the gravity field of the earth will change in quality.
