煤空干基灰分测定结果的测量不确定度评定

Evaluation of Uncertainty in Measurement of Air-dry Ash Content in Coal

文章分析了煤空干基灰分测定结果的不确定度来源,识别出不确定度分量,并对煤炭样品空干基灰分含量测定结果进行了不确定度评定。文章评定得出的是煤炭空干基灰分含量结果的不确定度,是实验室测定结果的不确定度。

This paper analyzes the source of uncertainty in the determination of air-dry ash content in coal,identifies the uncertainty components,and evaluates the uncertainty in the determination of air-dry ash content in coal samples.In this paper,the uncertainty of coal ash content in air dry base is evaluated,and it is also the uncertainty of coal ash content in laboratory.
