煤炭热值测量不确定度的分析

Analysis of Uncertainty in Measurement of Coal Calorific Value

依据ASTMD5 86 5标准对煤炭的热值Qgr,ad进行测定 ,依据JJG10 5 9对测定结果的不确定度进行了评定和表述 ,根据标准的要求和以往的工作经验 ,寻找了影响测定不确定度的各个来源 ,对各分量进行了合成和分析。

The gross calorific value in coal is tested in accordance with the standard ASTM D5865, and the uncertainty of the testing result is evaluated and described based on JJG1095. The analysis of each resource that will affect the determination of the uncertainty as well as the analysis and combination of each component are carried out as per relevant standards and formal experience.
