| 摘 要： | 采用博里叶红外光谱和Ｘ射线衍射分析方法，探讨了南华北区两类不同还原型镜质组化学结构物差异和随煤阶的变化。较强 原型镜质组明显比同煤阶较弱还原型镜质组含有较多的脂类结构，较少的芳环结构。随煤阶的增高，镜质组结构向芳环晶化程度增强的方向演变，芳香度、面网间距、晶核高度和宽度及芳环层数等结构参数均呈规律性变化。

| Abstract: | sing Fourier infrared spectra and X-ray diffraction, in this paper the difference of chemicalstructure of two types of vitrinite with different reductivity and their change regularities according to coalrank in the southern part of North China are studied. The vitrinite with stronger reductivity had morealiphatic structure and less aromatic structure than those of the vitrinite with weaker reductivity. Theevolution of structure in vitrinite involved with the crystallizing degree of aromatic structure increased. Someparameters of chemical structure in vitrinite, such as aromaticity, foe distance between surface network, theheight and width of crytal nuclear, and the number of aromatic ring varied regularily with coal rankincreased. |
