液体盐中氯离子测定的不确定度评定

Uncertainty Evaluation in the Determination of Chloride Ions in the Liquid Salt

依据测量不确定度的评定方法,结合液体盐中氯离子含量的测定方法,建立数学模型,确定不确定度的来源,计算各分量的相对标准不确定度,进而计算合成标准不确定度和扩展不确定度。

Basing on the assessment method of the measurement uncertainty and combining with the determination method of chloride ions in the liquid salt, a mathematical model to determine the sources of uncertainty was constructed to calculate the relative standard uncertainty of each com-ponent, the combined standard uncertainty and expanded uncertainty.
