The Earth: Is Gravity Drifting?doi:10.1038/10.1038/physci242113b0Nature
aThe earth's gravity field is almost the same as that of a sphere having the same average radius and total mass but increases slightly towards the poles. In gravity surveys, gravimeter measures gravity differences ,not absolute field strengths. 地球的引力场轻微地几乎是相同象那球形有同样平均半径...
