In Chapter 2, enantioseparations of four pairs of neutral and poorly water-soluble organophosphorus pesticides enantiomers were achieved by using natural chiral surfactant sodium cholate either with sodium dodecyl sulphate or with γ-cyclodextrin in nonaqueous solvent or aqueous-organic solvent systems.

第二章在非水介质或水相/有机介质中，或将天然表面活性剂胆酸钠与阴离子表面活性剂十二烷基硫酸钠构成混合手性胶束，或将胆酸钠与γ-环糊精构成二元手性协同体系，用于中性疏水有机磷农药对映体的手性拆分。

As a result, When different inorganic electrolyte and combined use of ionic and nonionic surfactants are applied,excellent dispersion system of alkalescent aqueous medium can be obtained.

结果表明：添加无机电解质及组合使用离子型表面活性剂和非离子型表面活性剂可以使纳米CeO2在弱碱性水介质中保持良好的分散性。

Gemini surfactants are novel surfactant with especial molecule structure, which are made up of at least two hydrophilic groups and two hydrophobic groups. They are connected at the level of the head groups by a spacer groups through chemical bond (covalent bond or electrovalent bond).

孪连表面活性剂是一种结构较为特殊的新型表面活性剂，其分子中至少含有两个亲水基和两条疏水链，在其亲水基或靠近亲水基处，由联接基团通过化学键联接在一起。

It indicated that the development trend of household detergent would be function, inspissation and liquid-state, and that of surfactants would be oleo-based or other special surfactants, meanwhile more and more attentions should be paid to their security.

指出家用洗涤剂的发展趋势将是功能化、浓缩化和液体化，表面活性剂将向油脂基和特种表面活性剂发展，其安全性也将倍受关注。

Scum and surfactant were also observed accumulated in system because lack of skimmer in the experiment equipment.

还观察到系统产生漂泥和表面活性剂在系统内积累的现象，指出表面活性剂积累是系统无撇渣装置所致。

Feature of production and marketing situation of both surfactant raw materials and products were pointed out.

分析了表面活性剂原料产销情况和表面活性剂产品统计数据呈现的特点。

It caused aggregation of purple membrane fragments at very low concentration. This effect might be attributed to its positive charges because cationic surfactant DTAB acted the same. On the other hand, melittin seemed to have behavior similar to CHAPS which has a rigid cholane ring,both had little effect on the conformation of retinal chromporphores.In consideration of the two-dimensional crystalline structure of purple membrane,melittin may form a rigid conformation such as α-helix on the surface of the membrane.

通过与三种在结构和电荷上不同的表面活性剂与紫膜的作用相比较，可以年出蜂毒作为带正电荷的分子与同样带正电的表面活性剂DTAB在引起紫膜凝聚方面表现相同；但在对紫膜可见光区的吸收光谱和圆二色谱的影响上却与具有刚性结构的CHAPS相似，表明蜂毒可在紫膜表面以一种刚性较大的构象存在，不能进入膜蛋白流水区的深层。

All that shows its a simple, fast and credibility method.(6) Using Chinese herbal medicine such as Gleditsia sinensis, tea seed bran, Tuber Fleece flower Root, Aloe, Radix Angelicae Sinensis, and surface active components such as AES, BS-12, K_(12), to compound Hibiscus Syriacus L.Chinese herbal medicine shampoo.

木槿叶水浸泡后搓出粘汁，作为洗发香波的表面活性剂和营养添加剂成分，加以皂荚、茶籽麸、何首乌、芦荟、当归等中草药营养成分和AES、K_(12)、BS-12等表面活性剂成分，复配成木槿中草药洗发水。

The proper hydrophobicity of SEPs was proposed to be an essential factor for the formation of honeycomb films, and large-sized SEPs are favorable for the fabrication of highly ordered honeycomb structures.

主要包括以下三部分内容：(1)我们利用表面活性剂替代多金属氧簇表面的抗衡离子得到表面活性剂包覆的多金属氧簇复合物，进而利用水滴模板法制备了基于多金属氧簇的多孔膜，并证实这种方法对于常见的多金属氧簇都是适用的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
