摘要
根据GB/T213-2008《煤的发热量测定方法》中8.4自动氧弹热量计法,测定煤的发热量,并以此为据建立了数学模型,分析了煤的发热量测量不确定度的来源及其种类,并对不确定度分量进行了计算、合成和扩展,最终报出测定结果。
In this paper, a mathematical model is established to measure the calorific value of coal according to 8.4 of GB/T 213 - 2008. 〈 determination of calorific value of coal 〉 , the sources and types of uncertainty is discussed, the uncer- tainty is calculated, combined and expanded ,then the measureing result is obtained.
