水准仪i角检验方法及其精度分析

Testing Methods for Level's "i" Angle and Their Accuracy Analysis

水准仪i角检验在水准测量中具有重要作用,本文具体介绍了水准仪i角检验中的弗尔斯特法、奈鲍尔法、库卡迈金法和日本方法等四种方法,推导了它们的检验公式,并对其测定精度进行了分析比较,进而提出了各种方法的适用条件及一些新的有参考价值的建议———精密水准仪i角检验最好采用弗尔斯特法,普通水准仪i角检验采用日本方法较适当。

The level's 'i' angle testing is very important in leveling. This paper introduces four testing methods for level's 'i' angle, namely, Frstner method, Nhbauer method, Kukkamki method and Japanese method. Their testing formulas are derived and their measuring accuracy is analyzed and compared. Then their application conditions and some new valuable advices are given: Frstner method is the best one for precise level and Japanese method is suitable for normal level.
