JJF1135-2005《化学分析测量不确定度评定》中对测量不确定度定义为表征合理的赋予被测量之值的分散性,与测量结果相联系的参数〔1〕,不确定度的评定已成为理化检验人员的基本技能。氟化物的测定常采用标准曲线法和标准加入法定量,采用标准曲线法评定不确定度已有文献报道〔2～7〕,庞敏晖等所写文章《连续标准加入法测定焚烧飞灰中氟化物的不确定度分 JJF1135-2005 “Evaluation of chemical analysis of measurement uncertainty,” the measurement uncertainty is defined as characterizing the dispersion of the measured values ​​assigned to the measurement results associated with the parameters [1], the uncertainty of the assessment has become Physical and chemical inspection staff’s basic skills. Fluoride determination is often used standard curve method and standard addition method to quantify the use of standard curve method to assess the uncertainty has been reported in the literature 〔2 ~ 7〕, Pang Min-hui and other articles written "continuous standard addition method for the determination of fluoride in incineration fly ash Uncertainty points
