The Study of the Test Method on Eccentric Errors of a Theodelite in Vertical Axes Series by Using Variance Analysis

• 摘要: 本文简要介绍了经纬仪竖轴系偏心差的检验方法和计算公式,并推导了精度估算公式,利用观测数据计算了偏心元素f以及同一台仪器采用三种方法所得结果的均值和方差,并对所取得的偏心元素进行了正态检验、粗差检验、方差检验,最后将检验结果进行了方差分析,对按三种计算公式所得的结果的精度进行了此较,并对各种方法的适用情况作了分析。

Abstract: In this paper, the test method and the computation formula of eccentric errors in vertical axes series are briefly described, and the precision of the formula is discussed as well. This paper also presents the result of the calculation of the eccentric element (f) by means of the observed data and the mean value and variance are computed by using three method on the same instrument. Not only normal examination, gross error examination but also variance examination, are made with respect to measuring errors. Finally, while relevant data are analysed by way of variance, a comparison of the three methods is made with regard to their precision, and the applicability of each method is also analysed.
