| 摘 要： | 测量不确定度是对测量结果可疑程度的一种定理表述.为减小实验误差,提高检测精确度,我们分析了饮料中菌落总数测量不确定的来源,评定了由重复性测量的分散性引起的测量不确定度.测量结果显示扩不确定度为0.04%.

| Abstract: | Measurement uncertainty is to describe the result of suspicious quantification.In order to decrease experimental error and increase accuracy,we analyzed the source of measurement uncertainty of the colony determination in drink,and assessed measurement uncertainty caused by dispersibility.The result shows that the expand uncertainty is 0.04%. |
