指示表的不确定度分析

Analysis of Uncertainty on Indicator

本文认为ＪＢ／Ｚ１８１—８２《３１７７—８２光滑工件尺寸的检验使用指南》中提供的指示表不确定度偏大。通过分析和计算后提出，指示表的不确定度略大于其示值误差的二分之一。

This paper thinks that the uncertainty of indicator provided by JB/Z 181 82《Usage Manual of 3177 82 Smooth Part Dimension Check》is very large.By means of analysing and calculating, this paper proposed that the uncertainty is rather too larger than its half of error of indication.
