It could be suggested that the glyceride biosurfactant was produced by C. antarctica at early stage for cell adapting the hydrophobic environment., and the alkane would be emulsified with the biosurfactant and made easy to be attached and up taken by cell.

由此可以推测，C.antarctica在正构烷烃中产生生物表面活性剂是在发酵前期，可能是菌体为了适应不良的生存环境而产生生物表面活性剂以乳化烷烃，增加与烷烃的接触能力，最终达到利用烷烃的目的。

DF-10 with capability of generating biosurfactants was screened out from sludge and Lamella-Analysis results showed that glycolipid was the main ingredient for the biosurfactants.

对筛选出的一株能产生表面活性剂的芽胞杆菌DF-10的发酵液进行薄板层析，表明所产表面活性剂的主要成分为糖脂。

TLC analysis of the ferment had classified the biosurfactant into glycolipid type. The diameter of oil displacement activity achieved 7.2 cm when use optimized medium. This biosurfactant had a good emulsification, the emulsified fluid could maintain at least 14 days.

排油圈分析和TLC分析表明，菌株E发酵液排油圈直径为7.2cm，表面活性剂为糖脂类生物表面活性剂；该生物表面活性荆叶菜籽油乳化能力校好，可以使乳化性能稳定保持14d以上。

Finally, based on the mixture , how the technical conditions , temperature % time-, alkaline dosage, influence the oil and gum content on refined waste silk was observed ,and then best technical conditions were concluded.

试验结果显示，在预浸工艺中，采用阴离子表面活性剂作为渗透剂比采用非离子表面活性剂效果更好一点。

The kinetics of hexachloroethane dissolution into surfactant solution was studied and a mathematical model describing the mass transfer process was developed.

为了解表面活性剂溶液对憎水性污染物增溶过程的影响因素，研究六氯乙烷在Tween20溶液中的增溶动力学过程，建立了六氯乙烷在表面活性剂溶液中增溶的传质模型。

It was found that surfactant decreases the observed mass transfer coefficient relative to water alone, however, the influence of surfactant on hexachloroethmane solubilization results in an overall increase in hexachloroethane dissolution rate.

发现六氯乙烷在表面活性剂溶液中的表观传质系数和纯水中的相比降低了，但由于表面活性剂对六氯乙烷的增溶作用导致其溶解速率总体上是提高的

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。

The results showed that the copolymer possesses good thickening property, and the performance of decreasing the interfacial tension between oil and water.

由于高分子表面活性剂具有高分子的增稠性和低分子表面活性剂的表面活性，在三次采油中具有广泛的应用。

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