食用菌中粗脂肪测定结果不确定度的评定

Evaluation of Uncertainty of Results of Crude Fat Measurement in Edible Mushroom

本文通过建立不确定度的数学模型,对食用菌中粗脂肪的测定不确定度进行了评估,分析了测定过程中存在的不确定度来源,量化了不确定度的分量,并求出合成不确定度和扩展不确定度,最终给出了不确定度测定结果的表示式。

A mathematical model of uncertainty was established in the paper to evaluate the uncertainty of crude fat measurement in edible mushroom. Sources of uncertainty in the process of measurement were analyzed. The components of uncertainty were measured and the combined uncertainty and the expanded uncertainty were gotten. At last, the expression of measurement results of the uncertainty was given.
