摘　　要：对饲料中维生素A含量的测量不确定度进行评定,分析测量不确定度的来源,建立数学模型,经计算得到维生素A的含量测定结果的扩展不确定度为46IU/g。在维生素A的含量测定过程中,标准溶液浓度是影响含量测量不确定度的主要因素。The measurement uncertainty of Vitamin A in feed was evaluated in paper. The source of the measurement uncertainty was analyzed, and the model of mathematical was established. The expanded uncertainty of the determination result in Vitamin A was 46 IU/g by calculation. At the determination of Vitamin A, the main factor of the content determination uncertainty was affected by the standard solution concentration.
