论相对论重力位及相对论大地水准面

On the Relativistic Geopotential and Relativistic Geoid

  • 摘要: 讨论了相对论意义下的重力位及大地水准面,指出了等时率大地水准面的缺陷,建议今后采用等频面及等频大地水准面的概念,给出了等频大地水准面与经典大地水准面的差异,同时给出了等频大地水准面的近似表达式。

     

    Abstract: This paper carefully examines the definition of the relativistic geoid, firstly in this paper, and suggests to apply the equi-frequency surface and the equi-frequency geoid to geodesy in the future. The possible direct measurements of determining the geopotential on the earth's surface as well as the equi-frequency geoid are proposed. The difference between the classic geoid and the equi-frequency geoid should be considerd, which has been investigated and concluded to be around 0.5 cm. Moreover, the expression of the equi-frequency geoid is given.
