摘　　要：检测结果是按照检测过程要求赋予被测量的一个量值,而为了更完整地表述检测结果,还应该给出一个不确定度值。依据GB/T 5009.131—2003对食用农产品中亚胺硫磷残留量开展检测工作,并对测定过程的不确定度进行分析,最终生成合成不确定度。结果表明,测定过程中引入的标准溶液、校正曲线、样品质量、体积、回收率、重复性等多个不确定度分量来源中,标准溶液配制引入的不确定度分量最大,扩展不确定度为15.6%,扩展因子k=2。The test result is a value assigned to the measured quantity according to the requirements of the testing process,and to more fully express the test result,an uncertainty value should also be given.This article analyzes and synthesizes the uncertainty of the detection work of azinphos-methyl residues in edible agricultural products based on GB/T 5009.131-2003.The results show that among the multiple sources of uncertainty components introduced during the experiment,such as standard solution,calibration curve,sample quality,volume,recovery rate,repeatability,etc.,the uncertainty component introduced by the configuration of the standard solution is the largest.The expansion uncertainty is 15.6%,and the expansion factor k=2.
