苯环

The benzenoid hydrocarbon are all nonclassical and, thus potentially aromatic.

苯环型烃都是非经典烃，因此，可能是芳香烃。

For the PEO-grafted polyaniline series with different contents of EO units, the benzenoid absorption peaks exhibited blue shifts in comparison with polyaniline, the shifts became greater as the content of EO units increased.

与聚苯胺相比，在共聚物的UV-Vis吸收光谱中，原来320nm处的苯环吸收峰出现了蓝移，其蓝移程度随着共聚物EO单元含量的增大而加剧，且Poly较Poly发生更大的蓝移。

The results of bioassay suggest that 2-methylthio-6-methyl-4-substituted pyrimidine and 4, 6-dimethoxy-2-substituted pyrimidine derivatives show herbicidal activity. In these target compounds, 4, 6-dimethoxy-2-substituted pyrimidine benzylamine and 4, 6-dimethoxy-2-Substituted pyrimidine benzylidene amine exhibit good herbicidal activity, and the herbicidal will be affected by the substituents in the benzene ring.

对分子库中的目标分子进行了生物活性筛选研究，发现其中的2-甲硫基-6-甲基-4-取代嘧啶衍生物和4，6-二甲氧基-2-取代嘧啶类化合物显示出除草活性，其中4，6-二甲氧基-2-取代嘧啶苄胺类化合物和4，6-二甲氧基-2-取代嘧啶亚苄胺类化合物具有较好的除草活性，而且其活性和苯环上的取代基有关。

UV and SMPE-GC-MS results confirmed that radical-oxidation and hightemperature pyrogenation controlled the sonochemical-oxidation of toluene, and mainmiddle-products included benzaldehyde, bibenzyl, dibutyl phthalate, et al., final products werecarbon dioxide and water. The reactive violet K-3R was chosen as a model compound to study the effect ofsonoelectrochemical degradation of nonvolatile pollutant.

以超声与电化学作用处理活性紫K-3R水样，二者协同效应明显，5V槽电压时60min K-3R脱色效率要比纯电场作用时高57.8％，纯超声场对活性紫基本无显著的降解作用，初始浓度、pH对超声电化学协同降解影响较大，实验建立了活性紫降解的动力学模型，经超声电化学处理后，K-3R共轭发色体系已基本被破坏，但溶液中仍有苯环等产物。

In conclusion, the experimental method was easily performed, the reaction time was short and the products were gained in high yield. The bromination was controlled by the large molecular structure of ammonium methylbdate.

研究结果表明，实验方法操作简单易行，反应时间段短，产物专一性好，后处理简单，并且收率较高，活化溴原子对苯环的进攻位置主要受到催化剂钼酸大分子结构的控制。

Flavonoids, derivatives of chromone or chromane, are built upon a C6-C3-C6 flavone skeleton in which the three-carbon bridge between the phenyl groups is commonly cyclized with oxygen. There are diverse group of plants containing flavone, isoflavone, flavonol, chalcone, ect.

黄酮类化合物系色原烷或色原酮的衍生物，其基本骨架具有C_6—C_3—C_6的特点，即指两个苯环通过中央三碳链相互连接而成的一系列化合物。

The orientation rule of substituting group s in benzene ring is often explained with electronic effect (inductive effect and conjugative effect).

有机化学教材中通常是从电子效应来解释苯环上取代基的定位规律。

The polymers substituted with hexyl and octyl on phenylene also show a nematic phase, however, the nematic phase disappears for the polymer substituted with decyl. The polymers substituted with alkoxy on phenylene self-organize into a lamellar structure, and their phase behavior shows obvious dependence on the alkoxy length.

苯环上烷基、烷氧基取代的聚合物都具有纤维状的特征形貌，当烷基、烷氧基碳原子数为6时在高温都存在一个向列液晶相，当烷基碳原子数增加到10时液晶相消失，而烷氧基碳原子数增加到12时该向列液晶相仍然存在。

Results The five purified ginkgolic acid monomers were GA13:0.,GA15:0.,GA15:1 ,GA17:1 and GA17:2 ,with a side chain of 13,15,17 alkyl or ethylenic radicals respectively on their benzene loop.

结果纯化的银杏酸5个同系物单体为GA13：0、GA15：1、GA15：0、GA17：1和GA17：2，其母核苯环上分别有1个13、15及17烷基或烯基的侧链。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
