1·Which coincide with the mean sea level surface is the geoid.

其中与平均海平面重合的面就是大地水准面。

2·The local refined Quasi-Geoid has been constructed in several regions and widely applied.

区域精化似大地水准面在全国多个地区已经建立，同时也得到了广泛应用。

3·The maximum difference of geoid undulation between the model and EGM96(to 70 degrees) is 2.

该模型与EGM96相比（70阶次），大地水准面起伏差异最大为2。

4·The main purpose of physical geodesy is to ascertain the outer Earth gravity field and geoid.

物理大地测量的主要目标是确定地球外部重力场和大地水准面。

5·As a criterion of the earth's equilibrium is taken the deviation of the geoid from the spheroid.

地球体与球的偏差，被用来作为地球平衡的判据。

6·The actual equipotent ial surface of the earth that corresponds to sea level is called the geoid.

相当海平面的地球实际等位面称为重力平面。

7·The invention discloses a disturbing gravity-based quasi-geoid land-sea seamless splicing method.

本发明公开了一种基于扰动重力的似大地水准面陆海无缝拼接方法。

8·The practical application of formulae to the absolute gravimetry and refineding geoid are discussed.

此外，还讨论了如何将它们用于绝对重力测量和精化大地水准面的实际中。

9·The quasi-geoid computed by geopotential model is fitted with the quasi-geoid measured by GPS leveling.

将地球位模型计算的阜新似大地水准面拟合于GPS水准实测的似大地水准面。

10·The geoid is also used as a reference surface from which to map the topographical features on the planet.

本次制作的地球水准面模型在绘制地球地貌时也将会被用来参考。
