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。
The characteristics of artificial measurement and automatic determination of vitrinite reflectance were comparatively analyzed. The automatic measurement methods and conditions highly correlated with the results of artificial measurement were given. The measurement results show that the reproducibility of automatic determination results is better than that of manual determination; the discrimination ability is comparable to that of manual determination. After the automatic measurement results are converted into manual measurement results, the deviation from the manual measurement results is less than the error range manually measured by different units.
