It was denoted that the toxicity of amphoteric surfactants is same as that of nonionic surfactants,which is lower than that of ionic surfactants and even lower than the toxicity of ethanol.

指出两性表面活性剂的毒性与非离子表面活性剂一样比离子型表面活性剂的低，甚至比乙醇的还要低。

The macropolarity of diaspore surfaces is high, and the adsorbed layer formed in such a manner is sporadic.

当阳离子表面活性剂浓度增加时，一水硬铝石表面的微极性降低，阳离子表面活性剂在一水硬铝石表面形成了胶束吸附，形成胶束的表面活性剂离子的数随其浓度的增加而增加，表面疏水性逐渐增强，直至完全疏水。

Experimental result makes clear, the main reason that structure of revulsive bursa bubble alters exterior activator is exterior activator embeds in the double element layer of bursa bubble, the inhomogenous sex that the exterior charge intensity that changed bursa bubble thereby and the exterior activator after embedding distributing in layer of bursa bubble double element.

实验结果表明，表面活性剂诱导囊泡结构改变的主要原因是表面活性剂嵌入到囊泡的双分子层中，从而改变了囊泡的表面电荷强度以及嵌入后的表面活性剂在囊泡双分子层中分布的不均匀性。

In this study, six surfactants with different ionic type, molecular structure, and phenanthrene (3-rings PAHs) were used to test the effects of surfactant to the degradation of phenanthrene, and to the combined toxicity with the phenanthrene.

本篇论文以六种不同离子类型、分子结构的表面活性剂和以菲为多环芳烃的代表，研究了表面活性剂对菲降解的影响，和与菲共存时的复合毒性，以及表面活性剂对菲在模拟生态系统中的迁移转化规律的影响。

Comparing with water, the optimal heat transfer enhancement is achieved near the critical micelle concentrations of surfactants. The degree of heat transfer enhancement is different with different surfactants and is influenced by solubility characteristic, ionic nature and chemical structure of surfactants. Boiling in surfactant solutions, when compared with that in water, is observed to be more vigorous with smaller-sized, more regularly shaped and faster departure frequency bubbles, but the surfactant solutions of Triton X-100 and Triton X-114 become cloudy for the cloud point of surfactants.

和水相比，表面活性剂强化池内核态沸腾换热的最佳浓度为临界胶束浓度；不同种类表面活性剂强化换热程度不同，它们与表面活性剂的溶解特性、离子类型和化学结构有关；溶液沸腾时，沸腾汽泡的脱离直径变小，脱离频率变快和更不易聚集，但非离子表面活性Triton X-100和Triton X-114由于存在浊点其沸腾溶液变浑浊。

The synthesis methods of amphoteric surfactants , their application to lavation cosmetic, and the merits and defects were systematic introduced.

系统介绍了两性表面活性剂在洗涤化妆品中的合成，应用，以及各自的优缺点，对开辟或拓宽两性表面活性剂的应用及研究和实际生产中选择何种两性表面活性剂提供了参

The good dispersion comes from the stable film existing in the interface. The important factors influencing the stability of the monomolecular film were CMC〓 and CMC〓. Great values of CMC〓 and CMC〓 can produce better film (with good stability in the interface).

而影响表面活性剂分子在界面上存在稳定性的主要因素是CMC〓和CMC〓，CMC〓和CMC〓的协同作用是影响分散体系中表面活性剂性能发挥的关键，也是评价表面活性剂性能优劣的工具。

Finally, we selected Gemini surfactant GNP, GTB and trimeric surfactant TNP to be used as emulsifier to achieve cationic slow breaking and quick-setting bituminous emulsion.

与结构类同的传统型乳化剂相比，Gemini表面活性剂GNP和GTB以及三聚体阳离子表面活性剂TNP具有更高表面活性和较强的荷电强度，因而更适用于慢裂快凝乳化沥青稀浆封层道路施工技术，其表面活性剂的结构对稀浆封层沥青乳液与矿料的拌和时间有重要影响，其拌和时间由长到短依次为：TNP＞GTB＞GNP。

Based on these results, it is reasonable to assume that cationic surfactant could form well-stabilized films on the surface of partially hydrated polyacrylamide solution, as a result a kind of surface active complex was formed between cationic surfactant and HPAM.

总之，本论文系统研究了阳离子表面活性剂和不同水解度的聚丙烯酰胺之间的相互作用，发现阳离子表面活性剂能在HPAM水溶液表面成膜，这和表面活性剂的HLB值有关，还与HPAM的水解度以及溶液的pH值有关；两者之间的静电引力是主要驱动力，这一过程又被表面活性剂链之间的疏水相互作用所增强。

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。
