一般分析试样与存查煤样测定结果核对允许差的确定方法研究

Research on the determination of check admissible error of testing results between general analysis sample and pack checking sample

介绍了一般分析试样与存查煤样的区别与联系,并对核对允许差进行估算及实验确定,指出一般分析试样与存查煤样测定结果的核对允许差不同于分析方法再现性临界差,提出了灰分和高位热值指标核对允许差的推算方法,并提供了用实验数据的统计处理来确定核对允许差的方法。

The differences and relations between general analysis sample and pack checking sample were introduced, and the check admissible error of testing results was estimated and finally determined by experiments. It was indicated that the check admissible error of testing results between general analysis sample and pack checking sample was different from the reproducibility critical difference. The calculation methods of check admissible error of determination of ash yield and gross calorific value were presented, and the further determination of check admissible error by statistical disposition of experimental data was put forward in this paper.
