苯环

Correlations of the chains and the phenyl rings were discussed at different conditions using order parameters .

以次序参数为依据，对不同条件下的链及苯环间相关性进行了探讨。

These results suggested that proper groups at 5-position on phenyl ring of sulfonylurea molecule might possess high herbicidal activity.

结果表明，在磺酰脲类分子苯环5位上进行结构改造，有可能得到高活性的化合物。

In addition, these ligands showed higher activity than thioether deveritives of phenyl oxazolines.

而且和苯环衍生的硫恶唑啉相比反应活性相对较高。

Their scavenging capacity also depends on the groups attached to phenyl.

其抑制超氧阴离子自由基的性能还同苯环上的取代基有关。

The 1, 3-disubstituted phenylene structure led to bend in the molecular chains of LCP-111 and LCP-116, so that their melting points are lower than that of Xydar, resulting in lower processing temperature and heat resistance.

由于LCP-111和LCP-116的分子链中均引入了间位取代的苯环结构，其分子链发生了弯折，因此它们的熔点均低于全对位结构的Xydar的熔点，但同时也降低了耐热性。

Red light-emitting polymer TPA-CNPPV was synthesized by alternatively introducing TPA and dicyano-substituted phenylene into the main chain.

通过将三苯胺与苯环上被对二氰基取代的PPV单元共聚，利用电子给体与电子受体交替的结构得到了发红光的聚合物TPA-CNPPV。

Due to cooperation and competition between the hopping integral and the on-site repulsion at different sites, the charge density and spin density can transfer between the radical sites and the phenylene ring sites.

由于不同格点上电子跳跃积分与Hubbard排斥能的合作与竞争，自旋密度和电荷密度可在苯环与自由基之间转移。

These polymers exhibit typical fibrillar morphology in the films. During heating in DSC, all the polymers substituted with alkoxy on phenylene show a nematic phase.

三、通过X-射线衍射、示差扫描量热仪和形貌表征等手段研究了苯环上取代基烷基、烷氧基长度对聚合物形貌、相转变过程等的影响。

The mesoporous TiO2 also showed high photocatalytic activities on photodecomposition of p-chlorophenol in bleaching wastewater, after 2 hours reaction under the UV-irradiation of 250W, the removing rate of p-chlorophenol was up to 95.3%.

光催化降解对氯苯酚表明介孔TiO2具有优异的催化性能，在250W紫外灯照射2h后，氯化有机物中的苯环特征峰完全消失，降解率可达95.3%。

This preparation overcome the association of rare earth in the materials and result in formation of the praseodymium triisooctanyl oxide/PS with high praseodymium content and high transparence, their fluorescence and heat capability were improved obviously.

它们的荧光强度有明显的提高，溶解性能、红外谱图及动态机械热分析证实了材料中存在镨与苯环中π电子的强配位作用导致材料形成交联网络结构。

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。
