表面活性剂的

The bacterium can better adapt to environment and the glycolipid was a high efficient surfactant, if the molecule configuration of this surfactant was ascertained and its yield was further improved, it has a great hope to be used as detergent or be used in microorganism enhanced oil recovery field, etc.

该菌株环境适应能力强，产生的糖脂表面活性剂高效，但需要对其分子组成进行进一步的鉴定并提高其产量，将有希望被用做清洗剂及应用于三次采油等领域。

5MN/m.(2) the biosurfactant was glycolipid type which was consisted of monosaccharides, disaccharides or trisaccharides group and fatty acid group which were combined by ester bond.

2产生的生物表面活性剂为糖脂类型，糖基通过酯键与不同链长的脂肪酸相连。

A surfaceactive agent reduces surface tension in a fluid or the interfacial tension between two immiscible fluids, such as oil and water.

表面活性剂可减小流体的表面张力，或两种不互溶流体间的界面张力，如油和水。

The quaternary ammonium salt of quinoline synthesized by alkyl halide and quinolin etc.,can be used as corrosion inhibiter during acidizing treatment of oil well when it is compounded with organic amine,suitable solvent and surfactant.

以烷基卤化物与喹啉等原料合成的喹啉季铵盐，当其与有机胺、适当溶剂、表面活性剂复配后，可作为油井酸化作业的酸化缓蚀剂。

Clearly, the structure of the surfactant at the interface plays an important role in reducing the interfacial tension.

可见，表面活性剂在界面处的结构对降低界面张力起到重要的作用。

Characteristics of dynamic interfacial tension are one of the important indexes of the performance of surfactants and polymers in EOR.

以表面活性剂和聚合物进行三次采油的方法得到人们的普遍关注。

And the effect of ion strength on the interfacial tension is a prominent factor.

然而对表面活性剂、聚合物及离子强度三因素共存时，对油水界面张力的影响及各因素对界面张力影响程度的比较还未见文献报道。

Therefore,investigating the dynamic interfacial tension of surfactants and polymers in EOR in the interests of fundamental research or industrial applications is of great importance.

油水动态界面张力的特征是评价表面活性剂和聚合物在三次采油中性能的重要指标。

In this paper,the dynamic interfacial tensions of different surfactants were investigated in their own field or other field.

因此，研究三次采油用表面活性剂和聚合物的动态界面张力具有重要的理论意义和实践意义。

Ionize molecules dissolve in water after the connected with the pro-oil-based baseband Yin charged hydrophilic surfactant.

分子溶于水发生电离后，与亲油基相连的亲水基带阴电荷的表面活性剂。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
