摘要
依据GB/T 212—2008《煤的工业分析方法》对煤样进行工业分析测定,分别对煤的水分、灰分、挥发分、固定碳进行不确定度评定,比较得出测量重复性引入的不确定度是各不确定度来源中的最大分量,并提出日常工业分析检测中可使用的、简化的测量不确定度评定方法。
The proximate analysis of coal was determined in accordance with national standard of GB/T 212-2008 'Proximate analysis of coal',the uncertainties of four origins analysis were evaluated respectively including moisture、ash、volatile matter and fixed carbon of coal.It is concluded that the uncertainty of repeatability is the largest component in various origins of uncertainty.A usable and simplified method to evaluate the uncertainty of proximate analysis of coal in daily work is proposed.
