摘要:

分析了煤镜质组反射率指标的统计属性和存在的偏差,用于判断煤化度的优势、煤种的劣势与判断的真伪性。比较了各种测定方法与表达指标的优缺点,讨论了识别镜质组方法对测定结果的影响,论证了不同测定方法中存在的系统误差不影响反射率分布图的应用。

Abstract:

This paper analyzed the mathematical statistics attribute of the coal vitrinite reflectance index and existing vitrinite deviations for judging coal rank and disadvantage of coal kinds,showing the advantages and disadvantages of various determination methods and expression index,with description of impact on the determination result by identifying vitrinite.The system errors among different determination methods not affecting the application of reflectance distribution has also been demonstrated.
