丙烯基

Chemistry of or pertaining to the allyl radical.

烯丙基的或与之相关的。

It is possible to achieve the conversion of allyl chloride and selectivity for epichiorohydrin as high as 99% on Ti-MWW.

在Ti-MWW催化剂上烯丙基氯的转化率和环氧氯丙烷的选择性都能达到99%以上。

Higher content of allyl ether led to higher curability in air.

随着烯丙基醚用量的增加，树脂在有氧状态下的固化反应能力增强。

This allyl type of resin is a highly transparent , colourless material

这种烯丙基型的树脂是一种高度透明的、无色材料。

This allyl type resin is a highly transparent, colourless material.

这种烯丙基型的树脂是一种高度透明的、无色材料。

No obvious difference was observed when 6′-OH of isonucleoside was free or was protected by allyl group.

异核苷6′-OH处于游离和烯丙基保护状态时的结果没有显著差异。

The influence of reaction temperature and time to production rate of tertiary amine was discussed;and the infrared attribute to Dimethyl ammonium allyl chloride was also carried out.

讨论了反应温度和时间间隔对叔胺产率的影响，并对二甲基二烯丙基氯化铵进行了红外表征。

The results showed that the reaction time was 5 h,reaction temperature was 60℃,the molar ration of allyl chloride to hydroxyl was 1.5,the molar rat...

实验结果表明，最佳工艺条件为反应时间5 h、反应温度60℃、烯丙基氯用量为1.5、季铵盐催化剂用量为聚乙二醇物质的量比的5%，聚乙二醇封端率达到85%以上。

We see the symmetry we have attributed to allylic particles on the basis of the resonance theory; the two ends of each of these molecules are equivalent

我们看到了曾经根据共振论而归因于烯丙基型粒子的对称性，所有这些分子中每个分子的两端都是等性的。

That is encouraging for palladium-catalyzed allylic substitution reactions which is difficult to use in industry due to the current low reactivity of catalysts.

而且，值得注意的是这类配体的反应活性都非常高，对于由于催化剂活性低难以在工业上应用的钯催化烯丙基取代反应来说，这无疑是一大喜讯。

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。
