| 摘 要： | 推导了利用地面重复重力观测结果计算大地水准面变化的计算公式;研究了利用相同点上的重复重力观测进行重力归化的理论和方法。并利用我国河西地区1996~2000年的重复重力观测资料对该地区的大地水准面变化进行了计算研究,本文在计算大地水准面变化模型中,提供了一个新的方法,采用了地面上相同点的两期重复重力观测值之差来计算大地水准面变化。

| Abstract: | In this paper,the formula which calculates the geoid changes is deduced by the repetition gravity measurement.Then the theory and method that the repetition gravity measurement is transformed to the geoid are discussed.Besides,Hexi geoid's changes are calculated and researched with the gravity variation data in the period from 1996 to 2000.This paper also adopts the same point repetition gravity measurement difference in calculating the geoid changing model,avoiding the complex gravity transform,and providing a new way to study the geoid deformation by using the difference of the two periods of repetition gravity survey on the same point. |
