摘　　要：利用统计分析方法,依据GB/T 33303—2016《煤质分析中测量不确定度评定指南》及测定煤发热量的测量模型,分析发热量的不确定度来源,计算每个来源的标准不确定度分量以及合成标准不确定度,最终得到干基高位发热量测量结果的不确定度。Using statistical analysis methods, this paper analysed the main sources of uncertainty of coal calorific value and calculated uncertainty of measurement results of gross calorific value on dry basis of coalaccording to the standard GB/T33303-2016“Guidelines for Evaluation of Measurement Uncertainty in Coal Quality Analysis”and the mearurement model for measuring the calorific value of coal.And the paper calculated the standard uncertainty components of each source and the combined standard uncertainty.
