摘要
建立了分光光度法测定水中氨氮含量的合成不确定度的数学模式。按照分析方法操作步骤的先后顺序,分别对标准溶液的配制、稀释和取样、标准曲线的绘制及样品的测定的不确定度分量进行了详细的分析和计算,得出测量扩展不确定度结果。
The paper erects math model of determined ammomial nitrogen compound uncertainty by prismatic photometer. Based on detailed alnlyse and account for confecting, dilution and sample of standard liquid, protracting of standard curve and uncertainty determining of sample, this paper educes measure enlargement uncertainty.
