On NaZSM-5, acetylene reacts with the water adsorbed on Na^＋ sites to form vinyl alcohol bound to the cations in zeolite through static attraction, corresponding to the weakly adsorbed species.

乙炔与HZSM-5中B酸中心上的水作用形成乙烯醇，后者在升温时变为碳正离子结合在分子筛的Al-O^--Si上构成强吸附物种。

The factors A and the rate constants are given at temperature range of 200-1200 K.The results in-dicate that the loss of aβ-hydrogen from 2-hydroxyethyl radical to yield vinyl alcohol and that a 1,3-hydrogen shift to form ethoxy radical have close A factors and rate constants.

用量子化学结果和Eyring过渡态理论计算了200－1200K温度范围内，标题反应的A因子和速度常数，结果表明，2－羟乙基脱去β－H生成乙烯醇与其经［1，3］重排生成乙氧基有相近的A因子和速度常数，且常温下速度较慢，反应难以进行。

Saturated small molecules such as glycerine, triethanolamine, saturated water-soluble macromolecules including corn starch and polyvinyl alcohol, and vinyl monomer are employed as modifiers for polymeric material surface.

本文首次利用Ce3+的紫外光敏特性，将其作为光催化引发剂，引发饱和小分子如单糖、多元醇，水溶性大分子如淀粉、聚乙烯醇，乙烯类单体如丙烯酸、丙烯酰胺、甲基丙烯酸甲酯等在聚合物基材表面的改性。

HE LOVED IT. You have saved my carpet, vinyl floor and shoes.

它很喜欢它，你们已经挽救了我的地毯，，乙烯地砖和我的鞋子。

However, vinyl will become dirty as any other product exposed to atmospheric conditions.

然而，乙烯将成为肮脏的暴露在大气条件的任何其他产品。

The vinyl does not interfere with the normal operation of my Pocket PC.

乙烯基不干预的正常运作，我的

There exists π-π electronic transition of benzene ring and unsaturated C=C bond in vinylidene of PDBOPV at 310 and 520 nm through ultraviolet-visible absorption spectrum.

研究表明，PDBOPV在310nm和520nm处分别出现苯环和亚乙烯基中的不饱和―C═C―双键的π-π*电子跃迁。

In this paper,two kinds of primers (uncrosslinking and thermo-curable)were synthesized by emulsion copolymerization of acrylate and vinylidene chloride.These primers were specially designed for the adhesion of many materials on poly ethylene terephthalatefilm and epoxy resin plate.

本文以丙烯酸酯类和偏二氯乙烯为原料，采用乳液聚合法，合成了非交联型和抗溶剂热固交联型两类专用于涤纶膜与多种材料、特别是与高分子量的感光材料之间粘接的乳胶。

The reaction takes place as soon as 3a is dissolved in solution. With the presence of a tethering terminal vinyl group bound to the vinylidene ligand, the [2+2] cycloaddition of two C=C double bonds readily occurred.

当有一乙烯基键结在丙二烯基上，分子内的两个碳碳双键会马上发生[2+2]的环化加成反应。

The spectral characteristics and photolysis quantum yields of ACRM composed of vinylidene chloride-methyl acrylate(VdCl2-MA) copolymer and pentamethoxyl red were measured.

本文研究了由偏二氯乙烯-丙烯酸甲酯共聚合物(VdCl2-MA)和五甲氧基红指示剂组成的酸敏变色记录材料的光谱特性，测定了其光分解量子产率。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
