摘　　要：本文对采用ICP-AES法测定玩具喷粉中可溶性铅含量过程中的不确定度来源进行了分析和评定。结果表明:在各分量中,由标准曲线非线性所产生的不确定度分量最大。因此,在日常检测中通过对校准曲线的不断测定,可降低样品测试的不确定度。The content of soluble lead in paintings on the toys was determined by ICP-AES,and the uncertainty in the determination was analyzed.It shows that： in all of the factors,the probability for uncertainty occured by stardard non-linear curve is the highest.Therefore,we can reduce the probability at the daily testing to the calibration curve.
