| Abstract: | In this paper,the dry basis ash of coal was determined in accordance with GB/T 212—2008 Proximate analysis of coal.According to JJF 1059—1999 Evaluation and Expression of Uncertainty in Measurement,each component of affecting the uncertainty in determination was analyzed and the standard uncertainty of each component was calculated and synthesized.And then the main influencing factors on uncertainty in determination of dry basis ash of coal were obtained by comparing the standard uncertainty of each component. |
