间隙法测量矩形角尺外角的不确定度分析

Uncertainty Analysis of the Measurement of the Outer Angle of the Rectangular Angle Ruler by the Gap Method

矩形角尺在实验室检测、现场调试的运用越来越广泛。矩形直角尺的检定及校准,既可以通过测微表直接测量,也可以通过间隙法间接测量。文章主要介绍间隙法测量0级及以下矩形角尺外角的不确定度分析。

Rectangular angle ruler is more and more widely used in laboratory testing and field debugging.The verification and calibration of rectangular square can be directly measured by micrometer or indirectly measured by gap method.This paper mainly introduces the uncertainty analysis of the measurement of the outer angle of the rectangular square with the gap method.
