表面活性剂

Surface modification and wetting agent basing on the suspension ratio and wetting were chosen and 30% nano-copper hydroxide wettable power was prepared.

运用TEM透射电镜和XRD衍射仪等检测手段对合成的原药进行了表征；通过试样悬浮率和润湿性优化了表面活性剂和辅助剂配方，制备了质量分数为30%的氢氧化铜可湿性粉剂。

The effect of different surfactants on α-arbutin bio-catalytic synthesis by Xanthomonas maltophilia BT-112 was investigated.

探讨了不同表面活性剂对嗜麦芽黄单胞菌BT-112( Xanthomonas mahophilia BT-112)催化合成α-熊果苷的影响。

Synthesis and characteristics of novel Zwitterionic Gemini surfactants.

新型两性Gemini表面活性剂的合成及其性能测定。

Its chemical structure ensures that the thickener does not react with cationic, anionic or zwitterionic surfactants and emulsifiers and does not require neutralization.

其化学结构确保增稠剂没有反应，阳离子，阴离子或两性离子表面活性剂和乳化剂，并且不需要失效。

Synergisms of zwitterionic surfactant between the mixed surfactant system of SDS/ C12-C12 were investigated.

采用界面张力法考察了两性表面活性剂C12-C12在癸烷中与十二烷基硫酸钠的协同作用。

The results showed that good synergism of all composite systems could be seen, especially the composite systems of anionic/cationic, anionic/zwitterionic surfactants showed better synergism than others.

结果表明：复合体系均体现了一定程度的协同性能，但阴／阳离子型、阴／两性型表面活性剂复合体系的增效协同性能更好。

At first, Oil phase conductivity change tendency is texted in this article, after mixed solution of Benzene,Tetrabutylammonium Bromid,cosurfatant which is added in KBr aqueous solution with different concentration, migration process of TBAB to the aqueous phase is studied.

本文首先通过电导率法测定了苯、四丁基溴化铵、助表面活性剂混合溶液中加入不同浓度的KBr水溶液震荡后油相电导率变化趋势，研究TBAB向水相迁移的过程。

Fluorocarbon surfactants,including derivatives of tetrafluoroethylene pentamer,oligo and perfluoroalkyls,were prepared.

由于一般有机液体的表面张力都较低，加入碳氢表面活性剂后，表面张力变化不大，甚至还会升高。

The surfactants used in syndet are mild and high efficiency, little skin irritation. As the pH value of syndet is neutral (7) or skin neutral (5.5), they neither alter the pH of the skin nor cause puffiness skin layer. Due to the absence of lime soap formation there is no problem of skin irritation causedby lime soap residues remaining on the skin.

合成皂所采用的表面活性剂更加温和，对皮肤的刺激性非常小，而且整体呈现中性(7)或者与健康皮肤相近的pH值（5.5），所以对皮肤pH值影响很小，同时避免了长期使用碱性皂引起的皮脂流失，由于没有钙皂形成，避免了钙皂沉积造成的刺激。

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。
