摘要
分析和讨论了汽油中铅含量原子吸收光谱测定法不确定度来源,对不确定度进行了评定。不确定度主要来源于最小二乘法拟合标准曲线产生的不确定度分量。
The source of uncertainty for determination of lead in gasoline by atomic absorption spectrometry was analyzed and discussed,and the uncertainty was evaluated.The uncertainty mainly comes from the uncertainty component generated by the least square fitting standard curve.
