摘　　要：依据GB/T213《煤的发热量测定方法》对煤的热值进行检测,并依据JJF1059 对测量结果的不确定度进行评定。简述煤发热量测量过程,分析了煤恒容高位发热量测定不确定度的来源及其种类,对不确定度分量及合成不确定度和扩展不确定度进行了评定。Measurement of calorific value for coal has been carried out according to GB /T213 《Measuring method of calorific value for coal》, and evaluation of uncertainty in measured results being made in accordance with JJF 1059. The process of measuring calorific value for coal has been briefly described, the source of uncertainty and its sorts in measuring constant volume gross calorific value for coal being analysed; the evaluation of components for uncertainty, resultant uncertainty and expanding uncertainty have all been carried out.
