摘要
依据GB/T212-2008《煤的工业分析方法》[1]测定煤炭挥发分、灰分,测试中使用仪器为电子天平、智能马弗炉。根据《测量不确定度评定与表示》(JJF1059.1-2012)有关规定建立数学模型,分析煤中挥发分、灰分测定中不确定度的来源,并对不确定度分量进行计算、合成和扩展,得出测量不确定结果。
The paper according to GB/T212 - 2008 ＂ Method for proximate analysis of coal＂, Determination of volatile matter, ash content of coal, the instruments for use in electronic balance, intelligent muffle furnace. According to the ＂ evaluation and expression of uncertainty in measurement＂ （JJF1059.1 -2012） the relevant provisions of the establishment of mathematical model, analysis of volatile matter in coal, ash measuring uncertainty sources, and calculation, synthesis and extension of the uncertainty components, finally obtains the measurement uncertainty of the results.
