| 4. | 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。 |
| 5. | 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。 |
| 6. | 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。 |
