Therefore it is considered that the decrement of gravityverticalgradient is caused by mountain mass distribution.
分析了佘山重力垂直梯度偏小的原因,认为这是由于山体质量分布引起的。

By very simple mathematical derivations, the practical expression of (Vzz), the expression of normal verticalgravitygradient, and the comment on the accuracy were given.
