镜质组 meaning in Chinese
vitrinite
Examples
- Separation of vitrinite group in bituminous coal
烟煤的镜质组密度离心分离方法 - 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。 - The results show that there is distinct relation between reflectance of vitrinite and coal classification , though this correspondence is relatively complex , especially in low - medium metamorphic bituminous stage where coals with same sometimes can be divided into different classes
研究表明：镜质组反射率与煤种之间的关系较复杂，特别是在中低变质烟煤阶段，相同变质程度煤往往归属于不同煤种，受煤岩组成和还原程度的影响较大。 - Based on analyses of about 600 coal - seam samples used for " classification of chinese coal " , the range of mean maximum reflectance of vitrinite ( r ( superscript o subscript max ) , % ) of different classes of bituminous coal was presented and the correspondence between them was discussed
摘要运用制定《中国煤炭分类》国家标准所依据的近600个烟煤煤层煤样实测数据，分析了中国不同煤种烟煤镜质组平均最大反射率的分布范围，探讨了烟煤镜质组平均最大反射率与中国煤分类系统之间的关系。 - Under general geological study of exploratory development of coalbed gas and underground gasification of coal bed in eastern depression of liaohe basin , authors apply the basic principle of coal geology and the data of vitrinite reflectance and technical analysis of coal to ascertain that coal classification are dominantely the lignite , long - flame coal and gas coal of coal - bearing upper section of third member of shahejie formation , and then dissertate the variational regularity between coal rank and buried depth in vertical and otherness of vertical limit of coal rank in different coal - rich regions
摘要运用煤田地质学基本理论和煤的镜质组反射率值及工业分析等有关数据，确定了辽河盆地东部凹陷古近系沙三段含煤亚段的煤种主要为褐煤、长焰煤和气煤；进而阐述了该煤段垂向上煤级与埋深的变化规律性、不同赋煤区各煤级垂向界限的差异性。
