As a result of aromatization of organic matter during the thermal cracking of original bitumen into gas,the aromatic hydrocarbons in the bitumen are characterized by abnormally abundant tetra-and penta-cyclic compounds,and predominated by parent aromatic compounds without alkyl chain,such as fluoranthene,pyrene,chrysene, benzofluoranthene etc.

沥青的芳烃组成独特，富含四、五环芳烃化合物，且以萤蒽、芘、和苯并萤蒽等无烷基取代的母体芳烃化合物为主，反映出沥青裂解成气过程中的有机质芳构化作用。

Halogenated aromatic compounds with great q〓(the most negative net atomic charges on an atom of the molecule), ENC (electron-nuclear attraction energy of the one-center term for the carbon atoms of the weakest carbon-halogen bond), qc (thenet atomic charges on the carbon atom of the weakest carbon-halogen bond) and E〓 tend to be reductively dehalogenated slow, while halogenated aromatic compounds with high values of △E (the difference of front-line orbital energy), EEC (electron-electron repulsion energy of the one-center term for the carbon atoms of the weakest carbon-halogen bond), Mw, q〓 and α tend to be reductively dehalogenated fast.

卤代芳烃化合物的整个分子的最负的原子净电荷，键序最小的碳卤键中碳原子的单中心项电子-核吸引能，该碳-卤键上碳原子的净电荷和E〓与该卤代芳烃化合物还原脱卤的速率常数负相关；而前线轨道间隙能，键序最小的碳卤键中碳原子的单中心项电子-电子推斥能，Mw，q〓和α与该卤代芳烃化合物还原脱卤的速率常数正相关。

Accordingly, aromatic compounds can be divided into three groups and a delocalized π system itself is always destabilized, the dependence of aromatic ring current upon the CT was reveled, and ring rigidity has been defined as a new aromatic index.

据此，我们提出了芳环化合物新的分类准则，揭示了芳香环流起因的必要条件，定义环的刚度为芳香性一个新判据。发现，分子内基团间的局部作用同它们对分子整体性能的影响是完全相反的。
