气相色谱法测定血样中毒鼠强的不确定度评定
付朝晖 黄雪祥 邓海中国疾病预防控制中心职业卫生所,北京100050摘　要:血样中毒鼠强含量的测定是判断是否中毒的重要依据，测定结果的准确性对临床诊断与卫生行政监督部门的决策具有重要的意义，而测量不确定度正是反映测定结果准确性的一个指标，因此有必要对毒鼠强测定不确定度进行分析评定，血样浓度为30．48μg／L，扩展因子k=2时，总不确定度UC=3．3μg／L。[著者文摘]

Abstract:Determination of Tetramethylenedisul in blood is the gist for deciding whether or not being poisoning. Accuracy of the result has a significant effect on both clinical judgments and decisions of the health administration and supervision department. The uncertainty is an important index reflecting the accuracy of results. So it is necessary to analysis the uncertainty of the measurement of Tetramethylenedisul in blood, When the concentration of blood sample is 30.48μg/L and expanded factor K is equal to 2, Overall Expanded Uncertainty is 3.3μg/L.[著者文摘]
