測(cè)量不確定度在機(jī)械天平計(jì)量檢定中的應(yīng)用研究

【摘要】測(cè)量不確定度是一種與結(jié)果相聯(lián)系的參量，能反映被測(cè)物的分散性。它的分析和評(píng)價(jià)是計(jì)量校準(zhǔn)中最關(guān)鍵的一項(xiàng)工作，不僅能反映測(cè)量值的離散性，而且也能為計(jì)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(jī)械天平》檢定規(guī)程的基礎(chǔ)上，總結(jié)了計(jì)量不確定度，并對(duì)其具體應(yīng)用進(jìn)行了分析。

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.
