自动和人工测定煤镜质组反射率的对比研究

THE CONTRAST BETWEEN AUTOMATIC AND ARTIFICIAL DETERMINATION OF COAL VITRINITE REFLECTANCE

摘要: 对比分析了煤镜质组反射率人工测定与自动测定的各自特点,给出了与人工测定结果高度相关的自动测定方法和条件。测定结果表明:自动测定结果的重现性好于人工测定结果;区分能力与人工测定相当。自动测定结果换算为人工测定结果后,与人工测定结果的偏差小于不同单位人工测定的误差范围。

Abstract: The characteristicts and distinctions between both the automatic and artificial determinations of vitrinite reflectance are compared and analyzed.The method and conditions of automatic determination,which are highly correlated with the results of artificial determination,are given.The determining results indicat that the result repeatabitity by automatic determination is better than that by artificial one,and the resolution capability is equal between them.After the results by automatic determinations transformed to those by artificial one,the deviations with the latter are less than the error ranges of the artificial determinations carried by different research units.
