At last, basic situation of surfactant industry in 2009 was forecasted.

预测了2009年表面活性剂行业的基本情况。

During the combination of the surfactant there are three points should be paid attention.

摘要表面活性剂是制约三次采油技术发展的关键因素。

A series of highly pure surfactant s was synthesized .

合成了一系列高纯度的表面活性剂。

The optimum reaction conditions and the influencing factors were studied. In the presence of gum arobic, arsenazo Ⅲ-barium in acid solution could combine with BSA to form a ternary complex leading to a redshift of absorption spectrum and significant increase of absorption peak intensity.

研究发现，在表面活性剂阿拉伯树胶存在下的酸性溶液中，偶氮胂Ⅲ-Ba配合物与BSA发生反应形成三元复合物，引起吸收光谱发生红移，吸收峰明显增高。

The formulations contain a nonionic polymer, a nonionic surfactant and an ionic tonicity agent, but are physically stable and easily re-suspended.

该制剂包含非离子聚合物、非离子表面活性剂和离子性补强剂，但是物理稳定的且易于再分散。

Secondly, the author prepared polypyrrole using emulsion polymerization method as well as water soluble polyaniline by adding a small amount of surfactant. Both knids of materials are used as sensing film of QCM trimethylamine gas sensors, respectively.

其次，采用乳聚法和添加少量表面活性剂诱导的方法分别制备了聚吡咯、水溶性聚苯胺，并将它们作为敏感膜材料制作了QCM气敏传感器。

Predominant operational variables, such as the separation and injection condition, surfactant and buffer concentration, are studied in detail.

详细研究并优化了电泳操作条件，例如分离及进样条件、表面活性剂浓度和缓冲液浓度等参数对分离效率和分离度的影响。

The effect on oil viscosity with ultrasound and surface active agent is studied in this paper.

本文研究了超声和表面活性剂对原油粘度的影响。

It is liquid cleaner composed of surfactant likehigh-effective lotion, wetting agent foam-killing agent.

产品简介：酸性清洗剂是由高效酸性洗剂、润湿剂消泡剂等表面活性剂复配而成的液体清洗剂。

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。
