摘要: 本文应用核磁共振法CP/MAS-13C-NMR和1H-NMR技术,研究高挥发份烟煤阶段(R°max≈0.64~0.74%)两种煤相的镜质组和镜质组氯仿可溶物的核磁共振特征,并结合元素分析、抽提物分离分析以及煤岩学特征等,对这两种煤相镜质组的结构进行研究。Abstract: In the paper, the NMR characteristics of vitrinites and their chloroform soluble matters from the two coal facies during the high volatile stage of bituminious coal (Rmaxo≈0.64~0.74%)are approached by the techniques of CP/MAS-13C-NMR and 1H-NMR. Moreover, with the basis of element analysis,separation of extracts and coal petrological characteristics,the authors have studied the vitrinite textures of the two coal facies.
