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。
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,the concept of the earth s normal density is proposed to solve the Earth s normal density distribution for Earth s core spheroid-crust mantle spheroid layer(CS-CMSL)model.
