表面活性剂

DF- 138 advanced water base rust inhibitor was replied and mixed by water soluble rust inhibitor, surface-active agent and other auxiliary.

DF – 138高级水基防锈剂是由水溶性防锈剂、表面活性剂及其它助剂复配而成。

The result show, pH of solution, the type and concentration of surface-active agent all have marked effect, pH change can transform the disperse behavior of attapulgite particle by altering granularity distributing in different range, influencing double electromotive force between particle and solution.

研究表明，水溶液的pH值、表面活性剂的类型和浓度对凹土的分散稳定性皆有显著的影响，pH值的变化改变了不同粒径范围的粒子总量分布，改变粒子与溶液间双电层电动势，从而改变凹土粒子的分散行为：由于凹土作为带电粒子在极性溶剂中容易达到物理分散的目的，因此，凹土在极性溶剂中的分散状况大大优于在非极性溶剂中的分散。

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。
