| 摘 要： | 根据当前的国际天文背景和实际需要论述了大地水准面概念的局限性和建立相对论大地水准面的必要性,采用广义相对论天体力学理论给出了大地水准面的两种形式的推广,指出了其中1阶后牛顿(1PN)等时面适合作为1PN大地水准面的定义,在目前和不远的将来可以满足天文和相关领域应用上高精度的需要.

| Abstract: | According to the present international astronomical background and actual need, this paper discusses the limitation of the existing geoid and the necessity to set up the relativistic geoid. Adopted the general relativistic celestial mechanics theory, two forms of the generalized geoid are proposed. The 1PN isochronized surface is suitable for as the definition of the 1PN geoid, which can meet the need of high-accuracy in astronomy and other related fields at present and near future. |
