The produced water which was made by crude oil dehydration containing polymer, alkaline and surfactant, brought many technique problems in the water treatment process system, this made the polymer flooding and water flooding water treatment technologies difficult to suit to the disposal requirement of the special water. The developed experiment research indicated that: because of the surfactant, the semidiameter of the oil droplets in the ASP flooding is much smaller than that in polymer flooding, and the stability of the oil droplets is higher than that in polymer flooding, The viscosity and combine difficulty of the oil droplets increased, and all the changes of speciality resulted in the increased difficulty in the ASP flooding produced water disposal.

三元复合驱采出液经脱水后得到的采出水中，因含有聚合物、碱和表面活性剂，给采出水处理工艺系统带来了一系列的技术问题，使已经应用于水驱和聚合物驱采出水处理的技术难以适应这种特性的采出水的处理要求，已经开展的实验研究表明：三元复合驱采出水中由于表面活性剂的存在，使采出水中油珠的粒径远远小于聚合物驱采出水，油珠的稳定性明显大于聚合物驱采出水；由于聚合物的存在，采出水粘度增大，使油珠聚并难度增大，这些特性的变化造成三元复合驱含油污水的处理难度大于聚合物驱。

It is showed that the properties of CMK-3 mesoporous carbon molecular sieve synthesized by hard template method have great influence on Ru dispersion. Higher specific surface area and appropriate pore size distribution is advantageous for sufficient dispersion of Ru on the supports.

采用固相热分解方法成功的合成了介孔氧化铬材料，考察了反应的温度、反应时间、前驱体和表面活性剂配比以及表面活性剂的种类等制备条件对纳米介孔氧化铬材料结构性能的影响。

Solubilization is unaffected by pH and the presence of small amount of electrolytes, but affected by temperature.

非离子表面活性剂的分子结构控制着胶团的内核大小，是其增溶能力的决定因素。污染物的极性越弱，表面活性剂对其的增溶能力就越强。

In recent years, the study and development of the zwitterionic surfactant cause much attention with the science and technology development, especially because of the high require for the mild kind of chemical commodity and environment protect.

近年来，随着科学技术的发展，尤其是人们对温和型日化产品及环境保护的要求日益高涨，因而对两性表面活性剂的研究与开发兴趣倍增，不仅在数量上显著增多，而且品种也在迅速增多，现已成为近年来发展最快的一类表面活性剂。

Especially discusses the enwrapping of magnetic nanoparticles and the surface active agent, the conditions of enwrapping (such as pH, temperature, surface active agent and stir speed) that have different effects on magnetic nanoparticles.

讨论了表面活性剂对磁性颗粒的包裹以及pH值、温度、表面活性剂的用量和搅拌速度等包裹条件对磁性颗粒的影响。

Similar lamellar hybrids can be obtained from octa(y-chloroammoniumpropyl) polyhedral oligomeric silsesquioxanes dodecyl benzene sulfonic acid sodium salt C_(18H_(29)NaO_3S, DBSS. Further research shows that different POSS to surfactant ratios result in different arrangement of layers: when there exists excessive POSS, the layer is arranged in a "Alkyl-POSS-POSS-Alkyl" sequence; while on the contrary, the layer is in "Alkyl-POSS" sequence.

实验研究表明，通过调整POSS和表面活性剂的物质的量比例可以改变片层结构，发现当POSS成分大大过量的时候，片层重复单元按照&烷基-POSS-POSS-烷基&顺序排列，对应较大的层间距；当表面活性剂成分大大过量的时候，片层重复单元按照&烷基-POSS&顺序排列，对应较小的层间距。

Many papers have been devoted to the interaction between small molecular hydrocarbon and fluorocarbon surfactants.
