苯乙烯的

Classification of the PFBs is briefly introduced. The synthesis, structure, properties and application of stilbene, naphthalimide and pyrene FBs are discussed.

简要介绍了聚合型荧光增白剂的分类，讨论了二苯乙烯、萘酰亚胺、花类聚合型荧光增白剂的合成、结构、性能及应用。

In our previous study, we found that the EtOAc extract of the roots contained many oligostilbenes which had multi-faceted bioactivities. Kobophenol A (1) is a stilbene tetramer, accounts for nearly 20% of the EtOAc extract.

我们研究发现金雀根乙醇浸膏的乙酸乙酯部位主要化学成分是二苯乙烯类化合物，具有多样的生物活性。

Are there any similar effects of stilbene derivatives on animals as they do on plants? In the present work, the chemical modification of resveratrol is investigated in detail. Furthermore, virtual screening, bioactivity evaluation and structure-activity relationship analysis are done on the designed molecules.

本论文力图探讨茋类化合物是否对动物体具有类似其在植物体中的免疫功能，以代表性的天然茋类化合物白藜芦醇(Resveratrol，3，5，4\'-三羟基-反-1，2二苯乙烯)为研究出发点，进行分子设计、虚拟筛选、活性评价和构效关系分析。

As the development of styrene industry, the production equipment becomes greater and greater.

随着苯乙烯工业的发展，其生产装置的规模越来越大。

Styrene took part in the formation of long chain branches and played an important role.

苯乙烯参与了长支链的形成，并对长支链的形成有促进作用。

To help the release, I now use 1.5 mm thick sheet styrene for the two large sides of the box.

以帮助释放，我现在使用的1.5毫米厚的薄板，苯乙烯为两个大方面的框。

Methods:54 workers exposed to styrene were selected as exposure group,25 workers unexposed as control group were similar like workers exposed styrene in age and sex.

选择接触苯乙烯工人54人为接触组，选择年龄、性别构成与接触组相似的不接触遗传毒物的工人25人为对照组。

The analytic methods are also studied : the concentration of styrene monomer is analyzed by gas chromatography , and the molecular weight of polystyrene is analyzed by viscosimetry .

建立了为评定阻聚剂性能配套的快速分析方法--近红外分析方法，即在单剂和工业剂评定中预测苯乙烯含量和聚苯乙烯分子量的四个近红外分析模型。

Second, the polymerization behaviors of alkoxyl substituted Cp titanocene for styrene syndiotactic polymerization were investigated.

其次，本文研究了烷氧基取代的茂钛络合物对苯乙烯间规聚合的催化作用。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
