根据化学分析中不确定度的评估指南提供的不确定度分析思路,对亚硝酸钠标准溶液浓度不确定度进行了评估,分析了影响测量不确定度的各个因素。测量结果表示为,置信概率为95%,k=2。
According to the uncertainty analysis method provided by the evaluation guide of uncertainty in chemical analysis, the uncertainty of concentration of sodium nitrite standard solution is evaluated, and the various factors that affect the measurement uncertainty are analyzed. The result of the measurement is that the confidence probability is 95% and k = 2.
