摘要
本文定义了基面关系式的概念,提出了基面与基本水准点考证的原则,分析了十六类基面关系式的计算方法,通过研究得出结论:基本水准点变动,冻结高程变动,基本水准点不变,冻结高程不变;绝对基面变化国冻差变化,绝对基面不变国冻差不变;冻结高程及国冻差有一项变动标准高程变动,冻结高程及国冻差都不变动标准高程不变。
This paper defined a conception of relationship of datum, proposed the principles of textual criticism of datum and basic benchmark and analyzed the computing method of sixteen types of relationship of datum. Through analysis and research, this paper reached a conclusion that if basic benchmark is changed,stationary elevation will change, and if absolute datum is changed, the difference between national datum and stationary datum will change; If one of stationary elevation and the difference between national datum and stationary datum is changed, the national elevation will change, otherwise, the national elevation will not change.
