研究了烷基苯磺酸盐表面活性剂在大庆油砂上的吸附特征。

The effect of various concentration of surfactant and sodium dodecylbenzene sulfonate on the aqueous photodegradation of sodium pentachlorophenate were studied.

研究了不同浓度的阴离子表面活性剂十二烷基苯磺酸钠对五氯酚钠在水溶液中光解的影响。

The effects of surfactant sodium dodecylbenzene sulfonate on 24-D adsorption in the soil were determined in laboratory studies.

研究了不同浓度的表面活性剂十二烷基苯磺酸钠对 2 4 D在土壤中吸附的影响。

A new family of sulfonate surfactants, in which the sulfonyl group is attached to one of the alkyl chains, has gained interest owing to their biodegradability, low sensitivity to water hardness, foaming ability, and lower skin irritability than the conventional alkylbenzene sulfonate.

一个新家庭的盐表面活性剂，sulfonyl集团隶属于链条之一，已获得利息烷基是由于它们生物降解性、低敏感性对储层水硬度、发泡能力和较低的皮肤过敏性比传统的烷基苯磺酸盐黄。

In order to improve their water solubility, 4"-fatty amido-3"-sodium carboxylate azobenzene-4-sodium sulfonates were synthesized. They are azo compounds with two hydrophilic groups of carboxyl and sulfonyl. They decrease the surface tension in dilute solution slowly, and show some surfactivity, but are not surfactants. The probable reason is their relative strong hydrophile. Furthermore, their colors are not fresh and far from our destination.

为了改善其水溶性，改用对氨基苯甲酸为原料合成了4′-脂肪酰氨基-3′-羧酸钠偶氮苯-4-磺酸钠盐，以偶氮结构为主的亲水基团上连有羧酸基和磺酸基两个亲水性较强的基团，但可能由于其亲水性太强，在稀溶液中只能缓慢地降低溶液的表面张力，具有一定的表面活性，但不是表面活性剂，而且颜色不鲜艳，距离我们的目标较远。

Objective: To observe the effect of surfactant in enhancing the efficiency of supercritical fluid extraction.

目的：考察表面活性剂提高超临界流体萃取效率的作用。

The products are widely used in stone, plate furniture, surface polishing of furniture paint and surface refurbishment of car paint.

该技术不同于传统的表面活性剂、皂化剂清洗原理，而是依靠不同液体之间的相变，在外力作用下产生强大"抓"力，"抓"去工件上的污物。

I understand the surface active agent basic composition structure, and the mechanism.

对表面活性剂的基本组成结构、作用原理有了比较深入的了解和探索。

The function of promotion related with the concentration of the surface-active agent.

这种促进作用与表面活性剂的浓度有关。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
