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。
Therefore it is considered that the decrement of gravity vertical gradient is caused by mountain mass distribution.
本文以极简单的数学推导，给出了正常重力垂直梯度的实用表达式，并对其精度作出了评价。
By very simple mathematical derivations, the practical expression of (Vzz), the expression of normal vertical gravity gradient, and the comment on the accuracy were given.
此外，还可以用激光拉曼光谱和在垂直静置液柱中的浓度梯度来证实和测定这种溶质团粒的存在。这种浓度梯度是过饱和溶液中由于重力的影响而形成的。
Moreover, the existence of clusters of solute has been detected by both Raman Spectroscopy and analysis of concentration gradients generated in supersaturated solutions under the influence of gravity.
