摘要
根据JJF1059.1-2006《测定不确定度的评定与表示》和QB 2238.2-2005《强化营养盐锌强化营养盐》的原理,对锌强化营养盐中锌含量的不确定度进行评定,建立不确定度的数字模型,系统分析并计算出营养盐中锌含量测定全过程中的各分量值结果标准不确定度及扩展不确定度,建立一种简便、适用的锌含量测量不确定度的测定方法。
According toEvaluation And Expressing Of Uncertainty In Measurement ( JJF1059.1-2006) and principle of Strengthen Nutrition And Salt Zinc Fortified Nutrient Salt (QB 2238.2-2005), a mathematical model was established, and stan-dard uncertainty and expanded uncertainty of component value in the process of zinc content measuring were systematically ana-lyzed and calculated. An applicable and convenient method to measure uncertainty of zinc content was developed.
