Molecular Orbital Theory and Pericyclic Reactions: Modern concepts of bonding and aromaticity.

轨道 理论和周环反应：关于化学键和芳香性的现代概念。

To have a good characterization of heavy hydrocarbons, the aromaticity correlation index has been developed on the basis of a wide range of data.

为更好地表征重烃，以广泛的数据为基础，开发了芳香度关联指数aci。

Aromaticity is the important concept in the field of organic chemistry and its application and the range of its application are increasingly enlarged.

芳香性是有机化学领域的重要概念，其应用与适用范围日益扩大。

The structural unit of extract consists primarily of aromatic rings and cycloparaffinic rings. The average molecular weight of the extract is 448. The aromaticity is 0.53.

萃取物的结构单元主要由芳环和脂环所构成，萃取物的平均分子量为448，芳碳率为0.53。

Topological resonance energy (TRE) and bond resonance energy (BRE) methods were applied to all the open structure isomers (both cations and anions) of C36CH2 to investigate their aromaticity.

用键共振能和拓扑共振能方法对富勒烯C36CH2开环结构中的所有可能异构体及其阳离子和阴离子芳香性进行了研究。
