该表面活性剂适合配置重油污型的洗涤剂，具有去油污力强，泡沫适中，稳定性能良好，无毒，成本低廉等优点。

Biosurfactants are used for emulsification, increasing detergency, wetting and phase dispersion , as well as for solubilization.

生物表面活性剂具有乳化作用、增加去污能力、水化能力、相分散性及溶解性。

Some of yellow azo pigments have been synthesized by coupling of acetoacetarylide derivates with different substituted nitroaniline diazonium salts. The relationship between pigment structure and shade, m. p., and thermal stability, and the, effect of addition of surface active agent on coupling reaction product have been studied. TGA and differential thermal analysis in air of the pigments and the variance of visible spectra reflectance have also been determined.

以不同取代的硝基苯胺衍生物为重氮组分与乙酰基乙酰芳胺衍生物为偶合组分，合成数种黄色颜料，观察了不同表面活性剂对其偶合产物性能的影响；研究了颜料分子结构与色光、熔点及热稳定性之间的关系；测定了颜料热重曲线及加热试样对可见光反射性能的变化。

应用高温液相二醇还原法，首次用1，10-癸二醇作还原剂，在两种表面活性剂存在下制备出磁性钴纳米粒子。

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。
