摘要
通过对不同变质程度煤的Ｘ射线衍射分析，探讨了各种煤的结构特点，提出了考察煤变质程度的新指标——变质系数，不仅合理，而且能较精确地反映出煤的变质程度。
By the X ray diffraction analysis of the coals with different metamorphic degree,the structual features of various coals are inquired,a new index is presented,by which the metamorphic degree of coal could be examined With the metamorphic index the metamorphic degree of coal could be not only indicated rationally but also could be reflected more accurately
