表面活性剂

The effects of length of hydrocarbon were detected in theory that, along with increase of carbon numbers, surface tensions were increscent gradually and interfacial tensions and cmcs were reduced gradually.

并从理论上考察了不同长度的碳链对表面活性剂性能的影响，随着碳氢链的增长，表面张力呈现增大趋势，临界胶束浓度和界面张力呈减小趋势。

所述非离子型表面活性剂选自聚合醚；与环氧乙烷缩合的山梨醇月桂基酯和山梨醇酐的混合物；它们的混合物。

The lauryl sodium sulfate was confirmed as the surface active agent in the indicator.

实验中确定了十二烷基硫酸钠作为加入指示剂的表面活性剂。

The protein envelop as well as the lipide membrane of HSV could be destroyed by surfactant, which destroys the DNA of HSV. Thus HSV loses the ability of infection. Sodium dodecyl sulfate is an anionic surfactant with biologic envelop denaturing potency.

HSV 的外部含脂质和蛋白质的包膜易为表面活性剂所破坏，引起胞膜通透性改变，使 HSV的 DNA 被破坏，从而失去感染能力。

SDS could dissolve the protein envelop as well as the lipide membrane of pathogen and cell. SDS is applied in light industry widely and safely, SDS is also made as microbicides in topical vaginal formulations to prevent the transmission of herpes and possibly other pathogens that cause sexually transmitted diseases,including HSV.

十二烷基硫酸钠(Sodium dodecyl sulfate，SDS)是一种阴离子型表面活性剂，为生物膜的最有效的溶解剂，它可以同病菌和各种高等动物的细胞膜的磷脂等脂质体结合而溶解，与蛋白质结合而变性。

Results showed that AOT reversed micellar systems provided a suitable micro-environment for biodiesel production. The optimal parameters were: the ratio of water and AOT 11, AOT concentration 50 mmol/L, temperature 40℃, pH 7, molar ratio of methano and oil 3, and rotating speed 180 r/min. The transesterification rate reached 90% when a 3-step methanolysis protocol was used.

研究结果表明： AOT/异辛烷反胶束体系为Candida sp.99-125脂肪酶催化提供了较为合适的微环境，在W0为11，表面活性剂浓度为50 mmol/L，温度为40℃，缓冲液pH值为7的AOT/异辛烷反胶束体系中，醇油摩尔比为3∶1，摇床转速为180 r/min，采用12h3次流加1 mol当量的甲醇，单批最高酯转化率可以达到90%。

Finally, in chapter 7, a simple method for the determination of critical micellar concentrations of SDS in different media was proposed based on current-monitoring.

第七章建立了一种简单的利用电泳谱图上电流的变化测定表面活性剂SDS在不同介质中的临界胶束浓度的新方法。

Micellar surfactant solutions were found to increase gas hydrate formation rate and storage capacity.

实验研究表明，表面活性剂胶束溶液可加快水合物的形成和提高水合物的储气质量。

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.

交际能力和语法的关系应该是目标与途径的关系。
