摘　　要：文章通过对萤石样品小体重测量不确定度进行分析评定,分析了影响结果的不确定度的来源,找出影响不确定度的主要因素,为实验室采取措施进行质量控制提供参考。通过实验计算出萤石样品的小体重为2.94 g/cm3,扩展不确定度为0.02 g/cm3(k=2)。Uncertainty evaluation of measurement results for the determination of small volumetric weight about fluorite samples was carried out in this article in order to find the influence factors of uncertainty. The sources of the total uncertainty that affect results was detected. The aim was to provide preventive reference for the quality control in laboratory. The small volumetric weight of fluorite samples was calculated in experiments. The expanded uncertainty was 0.02 g/cm3 as the small volumetric weight was 2.94 g/cm3.
