['eksinait]
壳质组
1.
According to the GC-MS analysis of soluble organic matters extracted from coal and exinite heated in closed system pyrolysis,one characteristic feature of all samples is the relative low abundance of tricyclic diterpanes in saturated hydrocarbon fractions with the detection in the C_ 19 to C_ 26 range.
通过对塔里木盆地煤岩与壳质组热模拟实验可溶有机物的色—质分析,煤岩和壳质组三环二萜烷具有低丰度、窄碳数(C19～C26)特征,且三环二萜烷主要来源于煤岩结构中具有三环萜骨架前身物的断裂释放。

Further study on their composition of organic matter shows that the content of exinite and maturation (vitrinite Ro<1.
进一步分析这套地层的有机地球化学特征后，提出壳质组含量和成熟度是决定石炭－二叠系能否生成轻质油的主要因素，并提出该区煤系地层生成轻质油的成熟度下限是镜质组反射率Ｒ０为１。

These include proximate and ultimate analyses,BET nitrogen adsorption and thermogravimetry,It is found that the H/C ratio and VM content of exinite concentrate are the highest in three macer al concentrates,and these parameters of vitrinite concentrates are higher than those of inertinite concentrates.
结果表明，壳质组具有最大Ｈ／Ｃ比和最高挥发分含量，镜质组的Ｈ／Ｃ比和挥发分含量高于隋质组；显微组分的粘结性，镜质组大于惰质组；镜质组和惰质组相比较，镜质组的着火点低、燃尽温度也低，具有较窄的燃烧区间；壳质组的着火点最低，但是燃尽温度要高于镜质组。
2) constitution of the crustal materials
