摘要: 从地球重力学的水准椭球和麦克劳林-皮蔡奇椭球出发,根据作者近十几年研究发表的参数椭球、纬向密度、准等位条件、似水准椭球等一系列观点和内容,提出“地球正常密度”概念,并求解出“地核椭球-壳幔椭球层”模式的地球正常密度分布。根据“地球正常密度”概念,提出“地球正常密度假说”及“板块运动重力学机制”的地球重力学研究的新课题。

Abstract: In terms of level spheroid of the earth gravity and Maclaurin-Pizzetti spheroid, according to a series of viewpoints and contents of parameter spheroid, latitudial density, quasi-isopotential condition, approximation level spheroid shown in authors’ recent decade year researches, we propose the concept of earth’s normal density, and solve earth’s normal density distribution for earth’s core spheroid-crust mantle spheroid layer (CS-CMSL) model. On the basis of the concept of earth’ normal density, we advance a new topic of earth gravity research for earth’s normal density hypothesis and slab movement gravity mechanism.
