改变觇标高度的三角高程测量

A Trgono - metric Leveling Method by Changing the Height of Measuring Mark

通过改变觇标的高度,利用普通光学经纬仪进行三角高程测量,阐述了其观测原理,分析了其观测误差,并 且与其他三角高程测量方法进行了比较。

A trgono - metric leveling method using optical theodolite through changing the height of measuring mark is discussed in this paper. This paper expatiates the observational principle, analyzes the observation error and explains the difference between this method and trgono - metric leveling method.
