| Abstract: | Silicon in low alloy steel was determined by inductively coupled plasma atomic emission spectrometry （ICP-AES）. The causes of the uncertainty in measurement were discussed by statistics. Mathematical model for evaluation of each uncertainty in measurement was constructed. The sources of each uncertainty and their effects on the total uncertainty were analyzed. Confidence interval of the results has been given. Silicon content in low alloy steel determined by ICP-AES and its confidence interval was given as 0. 472%±0. 014%. |
