| 摘 要： | 粗蛋白是评定饲料原料及其产品的重要指标之一,在理化分析中,测定结果存在不确定度。找出影响测量不确定度的因素,对各个不确定度分量进行评估和计算合成,并最终得出豆粕中蛋白质含量的合成标准不确定度和扩展不确定度。分析了不确定度的来源,提出减小不确定度的方法。

| Abstract: | The crude protein detection is an important indicator of evaluating feed raw materials and products,and all results inevitably have a measure of uncertainty in the process of physical and chemical analysis.In this paper,the factors affecting the measurement uncertainty are identified,and the combined standard uncertainty and the expanded uncertainty of the protein content of soybean meal are expressed by means of uncertainty measurement and calculation.Meanwhile,the sources of uncertainty are analyzed,and the methods to reduce the uncertainty are proposed. |
