摘要
提出了“似水准椭球”概念,给出了“似水准椭球”的“匀质分层”、“整体纬向”和“内匀外纬”3种模式的密度分布方式。针对“似水准椭球”密度分布的合理性和稳定性问题,初步提出了求解“似水准椭球”的拉格朗日函数和哈密顿积分的设想。
This paper presents the conception of “quasi level ellipsoid”. The three density distribution forms including density layered, total latitudinal and two-layer where outside density is distributed along latitude are discussed. In the light of the rationality and stability problem of density distribution of “quasi level ellipsoid”, we primarily put forward the idea to solve “quasi level ellipsoid” using Lagrange function and Hamilton integration.
