硫代硫酸钠标准溶液标定的不确定度评定

余奇飞漳州职业技术学院食品与生物工程系,福建漳州363000摘　要:对硫代硫酸钠标准溶液标定的不确定度分析，对其标定结果的质量进行了定量表征。结果表明，硫代硫酸钠标准溶液的浓度为0．1017±0．00035mol／L（k=2），测量结果重复性的不确定度对总体不确定度作用最大。[著者文摘]

Evaluation of uncertainty for determination of sodium thio-sulfate standard solutionYU Qi-fei Food and Bioengineering Department, Zhangzhou Institute of Technology, Zhangzhou, Fujian, 363000, ChinaAbstract:The quality of result of measurement is characterized quantitatively through the analysis of the uncertainty for determination of sodium thio-sulfate standard solution. The result shows the concentration of sodium thio-sulfate standard solution is 0.1017±0.00035mol/L（k=2）, and the uncertainty of repeatability of results of measurements contributes mostly to total comparing with others.[著者文摘]
