摘　　要：不确定度是对测量结果质量的定量表述,测量结果的可用性完全取决于其不确定度的大小,不确定度在现代检验领域已广泛应用。本文研究了按HJ/T 400-2007标准对车内空气中甲醛含量分析测定的不确定度,研究表明在使用HPLC对甲醛进行定量分析时,标准曲线对不确定度分量贡献最大。Uncertainty is a quantitative description of the quality of measurement results. The availability of measurement results depends entirely on the magnitude of its uncertainty. Uncertainty has been widely used in modem testing. In this paper, the uncertainty of HJ/T 400-2007 standard for the determination of formaldehyde in vehicle air is studied. The results show that the standard curve contributes most to the uncertainty component when formaldehyde is quantitatively analyzed by HPLC.
