水中挥发酚的测量不确定度评定

建立了分光光度法测定水中挥发酚的合成标准不确定度的数学模式，它由质量的标准测量不确定度和体积的标准测量不确定度组成。应用一个实例对这两部分标准不确定度的分量作了详尽的分析和计算，得出测量扩展不确定度结果。

To Evaluatethe Uncertainty of Detection of Volatile Phenolin Water

To construct the mathematical mode of detection combined standard uncertainty in detection of volatile phenol in water by spectrophotometry. The mode was composed by mass detection combined standard uncertainty and volume detection combined standard uncertainty. With a case, these two uncertainty's value were calculated and to get the value of detection expanding uncertainty.
