苯环

It is rather instructive for the further researches for the interaction of radiation with polymeric compounds, especially for the research of the ring benzene.

对于高分子化合物尤其是具有苯环结构的有机高分子化合物的外场作用特性的研究具有参考价值。

Attachment of Three Arms to a Benzene Ring.

扣押了三个苯环。

The influence of hydrophobic chains located at different positions on the benzene ring on the interfacial molecular behavior was investigated.

研究发现，苯环不同位置的取代烷基链长变化对扩张弹性模量和扩张粘性模量影响不同。

In the earlier stage, hydroxyl radical does not attack benzene ring to produce phenolic compounds.

在氧化反应初期，OH自由基不直接攻击苯环而形成酚类物质。

The sulfate can also be attached to a benzene ring, making a sulfonate

硫酸盐可连在苯环上，结构如图4.2-1所示。

Dozens of analogues with modification at benzene ring were synthesized by using a metal-catalysis coupling.

另外，采用金属催化的偶联反应我们合成了苯环区取代的一系列类似物。

The effect of dissociation on the photolysis should be mainly attributed to the formation of the negative oxygen ions,which led to the changes of the activities of benzene ring and substituent groups.

解离对酚类物质降解规律的影响主要是通过氧负离子的形成，改变苯环以及其他取代基团的活性而造成的。

However, the presence of steric hindrance and electron-withdrawing groups on the benzene ring would decrease the activity of phenols.

苯环上有供电子基团的酚类化合物反应活性比较好，而钝化基团的存在，则会降低酚羟基的反应活性。

There were 5 kinds of benzoate pollutants and their toxicities existing in the wastewater at least.

废水中至少存在5种以上苯环污染物及其生物毒性。

Objective: To study the anti-inflammation and anti-pruritus effect of bencycloquidium bromide.

目的：初步研究苯环喹溴铵的抗炎止痒作用。

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。
