摘要
本文论述了重力加速度的空间分布特性.求重力加速度除了按万有引力定律外,还必须考虑地球的半径、形状、自转和密度等变化情况.
The author elucidates the characteristics of space distribution of gravitational acceleration,and point out that it is impossible to determine the gravitational acceleration without considering the changes of the diameter,shape spin and density of earth.
