表面活性剂能够在自组装膜表面发生吸附，从而改变自组装膜的结构和性质，因此在电化学分析中有较广泛的应用。

The fluorescence properties and photolysis behavior of this CdS were studied in heptane and pyridine.

用反胶束法合成了用表面活性剂分子磺基琥珀酸双-2-乙基己酯钠盐进行表面修饰的CdS纳米粒子（记为CdS/AOT-SO-3），研究了这种纳米粒子在正庚烷和吡啶溶剂中的荧光及光解行为。

MoO3 organosol was obtained by using CTAB to modify the nanoparticles in MoO3, hydrosol and n-pentanol to extract MoO3 nanoparticles modified by CTAB. The effect factors on organosol were discussed extensively.

Efficacy: It takes pure natural plant polypeptide surface activators as principal composition to mildly dissolve dirt on skin surface and residual makeup to rebuild PH values for weak acids for derma membrane, making pores crystal clear and refreshing

功效：以纯天然的植物多肽表面活性剂为主要成份，温和溶解肌肤表面污垢和残留彩妆，重建皮脂膜弱酸的PH值，令毛孔通透清爽

Its hydrophilic groups is the inside carbonyl and amine base, and its lipophilic groups is the inside hydrocarbon chain and outer methyl. PAMAM of integral generation basically has not the surface activity. Its reason is that its outer groups is acylamino groups having very strong hydrophilicity so as not to reduce the surface tension of water. PAMAM different from traditional surfactant, have not critical micelle concentration, and exist in the form of "unimolecule micelle" in water.

结果表明：半代的PAMAM水溶液的表面活性与其分子具有两亲结构有关，亲水基团是内部的羰基和胺基，亲油基团是内部的碳氢链和外层的甲基；整代的PAMAM水溶液基本上没有表面活性，其原因是其最外层基团是酰胺基，亲水性很强，不能降低水的表面张力；树状大分子与传统的表面活性剂不同，不存在临界胶束浓度，在水中是以&单分子胶束&形式存在。

The spontaneous emulsifications of sodium dodecylbenzene sulfate, dodecane and three-component water system were simulated on the basis of the reasonable selection of particles and definition of interaction parameters between particles.

通过合理划分流体粒子和定义粒子之间相互作用参数，模拟了十二烷基苯磺酸钠、正十二烷和水三组分体系的自发乳化现象；通过附加固壁条件，模拟了在水动力作用下吸附在岩石表面的油珠发生破裂的非自发乳化过程，以及由于表面活性剂在岩石表面吸附而引起的润湿反转现象，比较了润湿反转前后残余油珠的运动情况。

ZnO nanoparticles were surface-modified by surfactants such as span-60,oleic acid,sodium laurate,andx as surface-modifier,and were added at the concentration of 0.5% in lquid paraffin to perform sedimentate test.

以山梨糖醇酐三油酸酯(span-60)、油酸、月桂酸钠和氟碳(C—Fx为表面活性剂对纳米氧化锌进行表面修饰，将修饰过的纳米氧化锌添加到液体石蜡中，使其质量分数为0.5%，进行沉降实验。

A part of microbial cells would autolyzed to release the intercellular alkanedegrading enzymes when they were cultured on alkane. Thus alkane could be degraded and synthesized alkane derivative with surface activity extracellularly. This surface-active agent would improve alkane emulsifying, and those unautolyzed cells could utilize the emulsified alkane sequentially.

微生物细胞在烃类基质中培养时，为了适应其疏水性环境以更好地摄取烷烃，会通过一部分细胞的自溶解体而使得胞内烃类代谢酶等释放，这样烃类在胞外被代谢生成具有表面活性的烷烃衍生物，该表面活性产物将促进烃类的乳化，使得剩余的未自溶解体的细胞可以借助生物表面活性剂而摄取降解烃类。

The borate surfactant SBW-181 was used for the modification experiments of calcium sulphate whiskers on the conditions of individual factors.

采用硼酸酯表面活性剂SBW-181对硫酸钙晶须进行了单因素条件改性试验，分别考察了改性剂用量、改性温度、改性时间和搅拌速率等工艺因素对硫酸钙晶须表面改性的影响。

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.

交际能力和语法的关系应该是目标与途径的关系。
