摘　　要：依据JJF1059-1999《测量不确定度评定与表示》的原理与方法,建立了液相色谱法测定乳粉中苯甲酸含量的测量不确定度评定的数学模型,并对测试过程中不确定度分量的来源进行了分析、量化和合成。结果表明:最终结果的不确定度主要由样品处理过程产生的不确定度引起。Based on JJF1059-1999 Evaluation of the Uncertainty of Determination and Expression,a mathematical model was established to assess the uncertainty of analyzing benzoic acid in milk powder by HPLC.Factors that were contributing to the uncertainty were analyzed,quantified and synthesized.The results showed that the uncertainty of this experiment is mainly caused by the treatment of sample.
