aromatic structure造句

• Fouriertransformation infro - red microspectroscopy micro - ftir technique was used to investigate the chemical compositions and structures of cutinite , vitrinite and fusinite from jurassic coals in tarim basin at different temperatures . the results show that the chemical structure of cutinite is mainly composed of long aliphatic - side chain with minor amounts of aromatic compounds . vitrinite is mostly composed of aromatic compounds , in addition to large amount of short aliphatic - side chain compounds . whereas fusinite are dominant by aromatic structure . the study indicates that cutinite is one of the best oil source - rocks , with the higher hydrocarbon - generation potential ; vitrinite is one of better gas source - rocks , and has medium hydrocarbon - generating potential ; fusinite has little hydrocarbon - generating potential . in addition , the components of aliphatic structures of cutinite , vitrinite and fusinite decrease , the aromatics are enriched and condensation of aromatic structure increases with increasing the temperature , and along with the rise of temperatures , the intensity of aliphatic structure and heteroatomic compounds decrease obviously , however the aromatic structure changes a little
  应用显微红外光谱技术，对塔里木盆地侏罗纪煤中有代表性的3种组分角质体镜质体丝质体在不同热模拟温度下的结构组成变化特征进行了研究，结果表明：角质体结构组成中含有较丰富的长链脂族结构，而芳香结构和含氧官能团的含量则相对较少与此相反，丝质体结构组成中芳香烃占绝对优势，而脂族结构含量则很少镜质体结构组成介于角质体和丝质体之间，含有较多的短链脂族结构和芳香结构。
