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]
