A novel method for synthesizing the amino-sulfonic acid series amphoteric surfactants was developed.

给出了氨基磺酸系两性表面活性剂的一种新合成方法。

Based on the experience of VES application, the amphoteric surfactants-based visco-elastic acid with better performance has been made at abroad recently.

根据VES使用的经验，近两年来，国外已研究出了性能优越的基于两性表面活性剂的粘弹性酸。

The Ag-TiO2 thin films were found to have an anatase phase.

Sb起到了类似表面活性剂的作用。

The result of the experiment showed that the fittest C/N ratio is 131 and the production of mutanolysin can be increased 2.45 times by adding up the inducer S. mutans cell into the liquid medium. At the same time the production was also affected to a different degree by feeding of surfactant and antifoam agent...

结果表明，最适C／N比为13∶1，培养基中加入诱导物变形链球菌菌体细胞，变溶菌素的产量可提高2.45倍，表面活性剂及消泡剂等的加入对变溶菌素的产生都有不同程度的影响，Tween20和植物油均可促进酶的产生。

In this dissertation, i has used inverse microemulsions technique to synthesize nano-magnetic particles . This method made nanometer sized cages formed by dissolving surfactant molecules in an apolar organic solvent. The chemical reactions were carried out inside the cages to synthesize nanoparticles. Because the growth of the naoparticles are limited in the cages, the particles were nanometer sized particles.

论文中本人以逆微乳化法去合成磁性奈米粒子，这个方式主要是利用在非极性有机溶液当中使溶解的界面活性剂构成一个奈米级的空洞，控制化学反应在空洞中反应合成粒子，也因为粒子生成受到空洞的限制，以致生成的粒子为奈米粒子。

Analyses of spectral structure and surface tension of solutions suggest that the hydrophobic hardrocarbon chain of surfactants was partly included in the apolar cavity of β-CD and the part with the polar head group of hydrocarbon chain located outside the cavity coiled over the top of β-CD, providing an effective protection for RTP.

组成测定表明溶液中形成了稳定的1：1：1/1-BrN：β-CD：AS三元包合物。光谱和溶液表面张力分析显示阴离子表面活性剂的疏水性烷基链有一部分被包合在β-CD空腔内，未被包合部分则绕曲在β-CD腔口处从而为空腔内1-BrN分子的磷光提供了有效保护。

The purpose of this paper was to investigate foam separation of aqueous surfactants solution.

本文对泡沫分离水中表面活性剂进行了研究和探索。

In general, surfactant has a potential in the remediation of contaminated aquifer and soil.

总之，表面活性剂在受污染地下水和土壤的修复领域有着广阔的应用前景。

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。
