从地球重力数据推导看地球内部构造

An Insight into the Earth's Inner Structures on a Gravity Evidence

在此之前，人们对地球内部构造的观点是：“地球的内部具有层圈构造，从地表向地心，密度和压力都不断增大，而且在地心最大”。笔者根据万有引力定律和大量推算，认为这种构造模式不合理，而且自相矛盾。于此提出了一种新的层圈构造模式：“地球从地表到地心，其间有一个高密度和高压力层，近地心的密度和压力都与地表很相近，可能比地表还小”。

There has long been an opinion that the density and pressure increase innerward and reach to maximum at the Earth's core. However, this view contradicts with the results from law of universal gravitation. In the author's opinion, the Earth is characterized by spherical structures among which there is a sphere of high density and pressure, and the density and pressure at the core are more or less similar to one at the surface, even smaller than the surface' s.
