二等环规标准装置测量不确定度估算

Estimation on Measurement Indetermination of Second-Class Gauge Standard Device

不确定度是与测量结构相联系的 ,用以表征测值的分散性。介绍了以二等标准环规为基准 ,用 82 8NES万能测长仪检定三等环规的测量不确定度的估算过程及结果。附表 3个。

The Uncertainty corresponds to measurement result and express seatter of measuring value. On the base of second standard ring gauge, the evaluating procedure and result is introduced, and measuring uncertainty of the third-class ring gauge is calibrated, using 828NES universal measuring length instrument.
