机械天平测量结果的不确定度评定与表示

Evaluation and Expression of Uncertainty of Measurement Result of Mechanical Balance

本文依据新的JJG 98—2019《机械天平》检定规程,选取实验室中稳定的机械天平为测量对象,建立机械天平测量模型,对影响机械天平不确定度的来源进行计算分析,最后合并得出该称量点测量结果的不确定度。

According to the new verification regulation JJG 98—2019 Mechanical Balance,the stable mechanical balance of the laboratory is selected as the measurement object,the measurement model of mechanical balance is established,the source of the uncertainty of the mechanical balance is calculated and analyzed,and the uncertainty of the measurement result of the weighing point is finally obtained.
