煤发热量测量方法的不确定度研究

摘要

Analyzed the uncertainty on calorific value of coal with the automatic calorimeter, found out the main factors which influence the coal heal and provide the scientific basis for the reliable degree. Taken automatic calorimeter method for the determination of calorific value of coal experiment as an example, according to the ＂ evaluation and expression of uncertainty in measurement （ JJF1059-1999 ）＂ the relevant provisions of the source of uncertainty was analyzed. The paper studied the uncertainty of automatic calorimeter in coal calorific value.%分析自动量热仪测定煤发热量的不确定度，找出影响煤发热量测定的主要因素，为评价检测报告的可靠程度提供科学依据。本研究以自动量热计法测定煤的发热量试验为例，根据《测量不确定度评定与表示》（JJF1059—1999）有关规定分析不确定度的来源．评定自动量热仪测定煤发热量的不确定度。
