中文摘要: 采用斐林氏容量法测定新疆若羌灰枣总糖的含量,较全面考虑了整个测定过程中不确定度来源,并对各不 确定度分量进行评定与量化,计算了合成标准不确定度和扩展不确定度。不确定度主要来源于斐林氏溶液配制。新疆 若羌灰枣中总糖含量测定结果表示为(71.3341±0.017)g/100 g,k=2。
Abstract:Total sugar content in ruo qiang hui zao was determined by Fehling's reagent method, various factors which might be affect the precision of the result were systematically analyzed and the uncertainty of determina- tion result was analyzed and quantified. It was found that the uncertainty mainly derived from the uncertainty of the preparation of the Fehling's reagent. The determination result was(71.3341±0.017)g/100 g, k=2.
