Several main non-ionic surfactants (AEO、TX、SpanTweem、EL) was used to emulsify liquid paraffin and di octyl sebacate and the anti-coalescence stability of the corresponding emulsion was studied, the impact of the presence of benzene and double bond in lyophobic moiety of surfactant and its length and matching with dispersed phase upon the interfacial viscosity and Gibbs elasticity was analyzed.

本文采用了几种主要的非离子活性剂(AEO、TX、Span-Tween、EL)来乳化白油和癸二酸二辛酯，通过对各乳液体系抗聚并稳定性的考察，分析了活性剂亲油链段的长度、苯环和双键的存在、及亲油链段与被乳化对象分子结构的匹配关系对界面粘度和Gibbs弹性的影响。

The effects of the brominated flame retardants,especially PBDPO,on the environment and human's health are attracting more and more attention.

溴系阻燃剂特别是多溴二苯醚(PBDPO类与环境保护及人类健康这一重大问题，在阻燃行业内正受到人们极大的关注。

Isoprene rubber was prepared with titanium catalyst modified by diphenyl ether ,and the effects of addition orders of various catalytic component on the monomer conversion,gel content and relative molecular mass were discussed in detail.

用二苯醚改性钛系催化剂合成了异戊橡胶，讨论了催化剂各组分加料顺序对单体转化率、产物凝胶含量和相对分子质量的影响。

The synthesization technics of MPEG- MAA was studied in this paper,which is an important intermediate used for preparation of polycarboxylate superplasticizer.

本文对制备聚羧酸系减水剂的重要中间体——甲基丙烯酸聚乙二醇单甲醚酯的合成工艺进行了研究，考察了反应时间、催化剂对甲苯磺酸的用量、阻聚剂对苯二酚的用量、反应温度及甲基丙烯酸与聚乙二醇单甲醚的用量比对酯化率的影响。

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.
