Petrographic analysis of bituminous coal and anthracite - method of determining microscopically the reflectance of vitrinite 烟煤和无烟煤岩相分析.第5部分:镜煤反射率显微测定方法
The method can accurately determine the reflectivity of a mirror , using combination of linear and folded cavities 利用直型和折叠型衰荡光腔结合，可以高精度地测定高反镜的反射率。
The regularity is obvious about the correspondence between mean maximum reflectance of vitrinite and classification of coals 但总的来说，烟煤镜质组反射率与煤种之间的关系规律性明显。
