表面活性剂

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。

The purpose is to study the enzyme characterizations of neutral protease fermented by synergism strains of Bacillus natto SH and B1. The optimal reaction temperature, optimal reaction pH, pH stability, thermal stability, metal ions, surface-active agent, inhibiter, simulated intestinal environment on enzyme stability were determined by Folin-phenol method, diversify graphs of residual activity were drawed.

为研究纳豆芽孢杆菌SH和B1配伍发酵产物中中性蛋白酶的性质，通过Folin-酚法测定中性蛋白酶的最适作用温度、最适作用pH值、pH稳定性、热稳定性和金属离子、表面活性剂、抑制剂、模拟胃肠道环境对酶活力的影响，绘制相对酶活力变化图。

Besides insolubility, the main factors to be taken into account are the viscosity and the content of oils, fats, surfactants and powders.

除了不溶性，主要还需考虑的因素包括粘度、油含量、脂肪含量、表面活性剂含量以及粉末含量。

Study on the interfacial tension of surfactant systems is meaningful in practice and theory.

研究表面活性剂体系的界面张力在理论上和实践上都有重要意义。

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。

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。
