摘要
测量不确定度是一种与结果相联系的参量,能反映被测物的分散性。它的分析和评价是计量校准中最关键的一项工作,不仅能反映测量值的离散性,而且也能为计量装置的应用提供更为精确的数据关系。文章在JJG 98—2019《机械天平》检定规程的基础上,总结了计量不确定度,并对其具体应用进行了分析。
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.
