因瓦水准标尺尺长改正检定方法的对比研究

目前国内外新旧水准标尺检定装置并存,有传统的特定分划检定和采用自动化装置的全尺分划检定两种方法。为比较两种方法的差异,用配对样本t检验法对两种方法测量结果的一致性进行检验,对复现性条件下测量结果的可接受性进行评价,并对全尺分划检定进行重复性试验。结果表明,全尺分划检定与分米分划检定的结果无显著性差异;同一种检定方法的重复性误差与两种检定方法的互差为同一数量级。

Comparative Analysis on Scale Calibration for Invar Levelling Staff

This paper compares the full-scale verification method with the decimeter verification method, which are used for the verification of levelling staff. By using a paired-samples t test, we compare the results obtained by the two verification methods, and evaluate the repeatability and reproducibility of the results. The results obtained by the two verification methods show no significant differences| the reproducibility error occurred in both verification methods and the difference which occurred in the comparisons obtained by the two verification methods are of the same order of magnitude.
