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。

The results show that the torsion energy and van der Waals interaction energy are the main types of energy and the substitution group has a great effect on the total energy of molecular. The aliphatic substitution would lead to the increase of total energy, while the aromatic substitution would lead to the decrease of total energy. The calculated results of bond length show that the bond length of aliphatic C—C is longer than that of aromatic C—C, which indicates that the rupture of aliphatic C—C is easier than that of aromatic C—C on heating.

研究结果表明，扭转能和范德华能是分子中的主要作用力，取代基对体系能量有明显影响，烷基取代基使体系能量增加，而苯基取代基使体系能量降低；脂肪C—C键长比芳香C—C键长长，说明脂肪C—C在受热过程中比芳香C—C更容易断裂分解。

The results showed that both LIR and LIR/aromatic oil could improve the processibility of NR/BR blend,and the plasticizing effect of the latter was more significant than that of LIR or aromatic oil alone resulting in lower compound viscosity,energy consumption and processing cost;and the NR/BR vulcanizate with LIR/aromatic oil possessed good physical properties and better dispersion of carbon black.

结果表明，LIR和LIR/芳烃油并用体系均能有效改善NR/BR混炼胶的加工性能，且后者的增塑效果较LIR或芳烃油单用时更为显著，其对应的混炼胶粘度较小，工艺能耗和成本较低；LIR/芳烃油并用体系对应的NR/BR硫化胶性能良好，炭黑在其中的分散性也较好。

After comparing the gasoline blending components and hydrocarbon group components of China with the facts of USA and Western Europe, we believe that with the 25Mt/a FCC gasoline base in our country , it is impossible to make hydrocarbon group composition obviously change through the method of dilution, and it is also not necessary to substantially enlarge the yield of alkylate to increas.

利用专门安排的加氢试验结果，进行分析和估算，对比了我国和美国、西欧的汽油调合组分和烃族组成，认为我国由于有25Mt/a的FCC汽油，不可能通过稀释的办法来使烃族组成有根本的改观，也没有必要采用大幅度扩大烷基化油产量来增加烷烃组分。

It revealed that the gaseous oxygen was related to the deep oxidation of hydrocarbon, since the breakage of C-C bond in allylic intermediate didn＇t exist during the process of reaction. This is due to the weak ability of lattice oxygen to attack hydrocarbon molecular.
