【摘要】測量不確定度是一種與結(jié)果相聯(lián)系的參量,能反映被測物的分散性。它的分析和評價是計量校準(zhǔn)中最關(guān)鍵的一項工作,不僅能反映測量值的離散性,而且也能為計量裝置的應(yīng)用提供更為精確的數(shù)據(jù)關(guān)系。文章在JJG 98—2019《機械天平》檢定規(guī)程的基礎(chǔ)上,總結(jié)了計量不確定度,并對其具體應(yīng)用進行了分析。

【關(guān)鍵詞】測量不確定度;計量檢定;應(yīng)用

Abstract:The uncertainty of measurement is a parameter related to the result,it can reflect the dispersion of the measured object,its analysis and evaluation is the most important work in metrology calibration,it can not only reflect the dispersion of the measured value,it can also provide more accurate data relation for the application of metering device. Based on the verification regulation of JJG 98—2019 Mechanical balance,the uncertainty of measurement is summarized and its application is analyzed.

Key words:measurement uncertainty;measurement verification;application
