| 摘 要： | 继"地球纬向正常密度假说"和"板块运动纬向重力模式"的提出之后,以参数椭球为工具,应用求解"地球纬向正常密度函数"的数学方法,在假设地核为匀质椭球和地壳并入地幔的前提下,初步求解出满足极点与赤道重力条件的"地幔纬向正常密度函数",从而使得"地幔纬向密度异常"的提法在理论上获得了依据.

| Abstract: | After presentation of 'Latitudinal normal density hypotheses of Earth' and 'Latitude depended gravity mode of Earth plate movement', this paper by means of parametric ellipsoid concept, using the mathematic method of deducing latitudinal normal Density function, assuming that Earth core having even density and Earth crust pushed into Earth mantel, the latitudinal normal density function of mantle is given out, which satisfies the pole and equator gravity condition. Therefore the latitudinal density anomaly of mantel would have theoretical bases. |
