The effect of coconut amine on the viscosity and stability of residue asphaltene system was studied and the change in viscosity and colloid stability with coconut amine content was discussed briefly.

考察了表面活性剂椰子胺对石油沥青质体系粘度和胶体稳定性的影响，初步探讨了粘度和胶体稳定性随椰子胺质量分数变化的原因。

The results of moisture adsorbability and water retentivity show that this type surfactant has good moisture adsorbability but its water retentivity is not so good.

吸湿保湿性结果表明，该类表面活性剂具有较好的吸湿性能而保湿性能相对较差。

Having investigated composites of EP coating ultramicro iron using ATPU as surface agent, results showed that with increasing amount of ATPU, density , complex permittivity and complex permeability of composites decreased, and retentivity and coercivity increased.ε"μ"

用ATPU作表面活性剂制备核壳结构复合粒子时，随着复合时ATPU用量的增加，复合粒子的密度、复介电常数和复磁导率逐渐减小，剩磁与矫顽力逐渐增大。

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.
