Characteristics of preparation and separation, and some other technological features were further studied. It concluded that vitrain is low in density and in HGI. It is rich in lighter and corser parts of the coals.
然后，进行了各煤岩组分的工业分析、元素分析、密度测定、HGI测定、表面基团测定、表面电位测定、润湿热分析、比表面积和孔经测定，进而深入研究了其分选性质和其他工艺性质。

But, fusain is high in density and in HGI. It is usually concentrated in the coals of heavier and finer parts. Less oxygen functional groups exists in vitrain even if the total oxygen is high. However, more oxygen functional groups is found in fusain though total oxygen is low.
指出，镜煤的密度较低、HGI值较小、易富集于密度较氢的粗粒径煤中，尽管其总氧含量较高、但是含氧官能团的数量相对较低，丝炭的密度较大、HGI值较高、易富集于较重的细粒径煤中，其总氧含量尽管较低、但是含氧官能团的数量较高。

Research on Coal-forming Environment and Sequence Stratigraphy in Coal Measures Strata;2. The results show:1, there were the differences between the characteristics of the coalification between the Taiyuan Formation vitrain and the Shanxi Formation vitrain which were formed in differencial coal-forming environment s, and the differ.
结果表明：在高煤级煤早期阶段，形成于不同成煤环境的太原组煤与山西组煤的煤化特征仍有差异，在第三次煤化作用跃变之后这种差异逐渐缩小消失；高煤级煤分别以第三次和第四次煤化作用跃变为界，呈现出阶段性演化的特征，每阶段的演化机理有所不同；第三次煤化作用跃变中大分子结构的演化以芳构化作用主为，第四次煤化作用跃变则以强烈的环缩合作用占优势。
