本文总结了作者等最近十年来对地球重力学“水准椭球密度问题”进行研究的初步结果,首次提出了“密度水准椭球”概念,给出了从“匀质椭球”、“参数椭球”、“纬向密度椭球”、“似水准椭球”到“密度水准椭球”的研究路线,并对该问题的研究前景进行了讨论.
This paper reviewed the study on density of the level ellipsoid proposed by author and his colleagues during last ten years, presents the conception of Density Level Ellipsoid. These research approaches include uniform ellipsoid, parameter ellipsoid, latitudinal density ellipsoid, quasi-level ellipsoid and density level ellipsoid. The prospect of the research is discussed.
