乙烯基

Chlorine atoms were selectively introduced into the chlorin ring based on different reactivity between vinyl group at 3-position and 20-meso position by electrophilic addition and electrophilic substitution using hydrogen peroxide/hydrochloric acid, N-chlorosuccinimide, hydrogen chloride (or concentrated hydrochloric acid) as chlorinating reagent.

以过氧化氢/盐酸、N-氯代丁二酰亚胺、氯化氢为氯化剂，根据3-乙烯基和20-meso-位的不同化学反应活性，通过亲电加成和亲电取代反应，在二氢卟吩环上选择性地引进氯原子，完成8种未见报道的具有叶绿素-a基本碳架的氯代二氢卟吩衍生物的合成。

It may be blended with more rubbery polymers or copolymerized with other vinyls to obtain products with desired properties.

混以增塑剂或与其它乙烯基一同聚合，可得到依照模具形状的制品。

Then,the seed-emulsion was respectively copolymerized with many kinds of acrylates to form the excellent silicon-acralyte emulsions.

探讨了乳化剂加入量、种子乳液量、乙烯基硅含量(Vi-D4用量)、活性物含量等因素对硅-丙乳液转化率和接枝率以及乳胶粒形貌和乳液粒径分布的影响。

I wish that Halloween costumes for little girls involving vinyl boots or corsets were just silly and fun.

我希望包括由乙烯基制成的长筒靴或着紧身胸衣在内的小女孩万圣节服饰纯粹属于愚蠢和开玩笑的。

Okay, well, at least vinyl is easy to clean, but there's always the problem of scuffs, tears and poking holes in it, a condition which was already showing up.

好，好，至少乙烯基容易清洁，但总有问题scuffs ，眼泪和撬拨的洞穴，条件是已经显示出了。

Various coatings are available including varnishes, lacquer, vinyl, and polyester films.

Shaddock hit the Exhibition Hall, home owners from around the world selected household decorations: different colors of glass vases, all sorts of candles, candle stand, and a variety of pillow and cushion-shaped grapefruit hit home ... the Exhibition Hall owner selected in 2006, are from France designed vinyl wall stickers: a variety of styles, a variety of sizes, a variety of patterns.

柚创家居展示厅拥有来自世界各地精挑细选的家居装饰品：颜色不一的玻璃花瓶，各式各样的蜡烛，蜡烛支架，以及各种形状的抱枕和靠垫…柚创家居展示厅拥有2006年的精选，是来自法国设计的乙烯基墙上贴纸：多样化的风格，多样化的大小，多样化的图案。

The results suggested that the reaction temperature, the ratio of oil to water, the amount of ethyl cellulose as dispersant, initial monomers composition, the drop manner and the amount of initiator, the stirring speed, the pH of the buffer and the elution process have great influence on the morphology such as diameter of the hydrogel beads.

研究结果表明，采用反相悬浮聚合法，以丙烯酰胺和N-乙烯基吡咯烷酮为共聚单体，N，N'-亚甲基双丙烯酰胺为交联剂，牛血清白蛋白为模板，可以制备BSA印迹共聚物微球；反应温度、水油比、乙基纤维素分散剂用量、初始共聚单体配比、引发剂用量和加入方式、搅拌速度、水相pH值以及后续洗脱条件等均对粒径等微球结构和形态产生明显影响。

The split between the two groups can hardly be papered over.
