Organic our country high polymer flocculant already has commercialized at present having several breeds such as PAM , polypropylene acidamides and carboxyl methyl cellulose only , studies innocuous high-effect organic synthesis high polymer flocculant (the ammonium equality gathers the sum copolymer kind if alkyl alkene propyl group halogenates waiting), optimizes it's the cost reduction composing handicraft.

目前我国有机高分子絮凝剂已商品化的仅有PAM、聚丙烯酰胺和羧甲基纤维素等几个品种，研究高效无毒的有机合成高分子絮凝剂(如烷基烯丙基卤化铵的均聚和共聚物类等)，优化其合成工艺降低成本。

Interpenetrating network films were prepared by acrylated polylactide with low molecule weight and chitosan.

利用丙烯酰化的低分子质量聚乳酸和壳聚糖形成互穿网络结构的薄膜。

And we also research the impact of methylating on hydrogen bond and stacked bond in base pairs under considering water molecules.

研究结果表明，烷基化之所以能造成碱基错配是它可使碱基的质子迁移或烯醇互变现象容易发生，改变原有原子的电荷分布或配对模式，同时碱基自身的互变异构体会跟烷基作用，致使互变异构体能够稳定存在，影响正常碱基配对，引起碱基诱变，造成生理疾病的发生。

The present invention is one kind of supported olefin polymerizing catalyst of metallocene and post-transition metal and its reaction process of catalyzing ethylene polymerization.

本发明是关于一种负载化茂金属和后过渡金属烯烃聚合催化剂及其制备方法，以及其催化乙烯聚合的反应工艺。

The synthesis of alkylcyclohexylbenzoic acid: take the synthesis of ethylcyclohexylbenzoic acid as a typical example. With the AlCl3 as the catalyst, cis+trans acetylcyclohexylbenzene is synthesized from the reaction of acetyl chloride, cyclohexene and benzene.

烷基环己基苯甲酸的合成研究：主要研究了乙基环己基苯甲酸的合成，以乙酰氯、环己烯、苯为原料，三氯化铝为催化剂，合成乙酰基环己基苯，用水合肼、氢氧化钾、一缩二乙二醇经过高温加热还原羰基(Wolff-黄鸣龙还原)，将所得到的乙基环己基苯用乙酰氯进行傅克酰基化得到乙基环己基苯乙酮，所得中间体经过处理之后直接得到反式产物，将反式异构体的乙酰基氧化得到反式烷基环己基苯甲酸。

Using it as emulsifier for the microencapsulation of docosahexaenoic acid spirulina oil, good results are obtained.

以合成的辛烯基琥珀酸淀粉酯为乳化剂应用在DHA藻油的微胶囊化中，取得了非常好的效果。

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.
