摘要
继“参数椭球”概念提出以及“参数椭球”的地球重力学性质和数学性质得到初步研究之后 ,本文研究了参数椭球的密度分布问题。结果表明 ,当参数椭球内的密度界面无限趋向表面时 ,两种“准等位条件”是完全等价的。在参数椭球的“准等位条件”下 ,匀质分层的密度分布并不符合地球的实际密度分布。因此 。
After Parameter Ellipsoid concept has been presented,as well as its geophysical and mathematic characteristics have been preliminarily studied,we research the problem about density distribution of Parameter Ellipsoid in this paper. The results indicate:when the inner density interface extends to the Earth surface,these two quasi-equal level condition are completely equivalent. Under the condition of quasi-equal level condition,density distribution of homogeneous layers are conflict with the real Earth density distribution. So the density of the Earth is related to latitude.
