The preparation of avermyctin emulsions in water was achieved by mixing the surfactants polyoxyethylene (10) octylphenyl ether (OP10), polyoxyethylene styrenated phenol ether (602), and polyoxyethylene (40) castor oil ether (EL-40) with polyoxyethylene (20) castor oil ether (EL-20), separatively. Emulsion stability was investigated by analyzing the hydrophile-lipophile balance, critical micelle concentration, and surface tension. Then, the surfactants of polyoxyethylene polyoxypropylene styrenated phenol ether (1601), block copolymer (L64), and octyl phenyl polyoxyethylene phosphonate were added to the emulsion made by blending EL-40 and EL-20, separatively. The stability of the emulsions was investigated further and discussed in terms of droplet size, surface tension, and zeta potential.

首先将辛基酚聚氧乙烯醚(OP10)、苯乙烯基酚聚氧乙烯醚(602)和蓖麻油聚氧乙烯(40)醚(EL-40)分别与蓖麻油聚氧乙烯(20)醚(EL-20)复配制备阿维菌素水乳剂，从亲水亲油平衡值、临界胶束浓度、表面张力等方面分析了二元表面活性剂复配对乳液稳定性的影响；其次，在EL-40与EL-20复配基础上，将苯乙烯基酚聚氧乙烯聚氧丙烯醚(1601)，嵌段共聚物(L64)和辛基酚聚氧乙烯醚磷酸酯分别添加到乳液中，从粒径、表面张力和zeta电势等方面考察三元表面活性剂复配对乳液稳定性的影响。

Copolymerization by micellar polymerization [8] is the most usual method in which a surfactant such as sodium dodecyl sulfate is used in an aqueous solution to solubilize the hydrophobic monomer.

共聚胶束聚合[ 8 ]是最常用方法，其中表面活性剂，如十二烷基硫酸钠，是用在水溶液中，以solubilize疏水性单体。

The experiment shows that the reverse micelles of DAA, DAP and DAB are able to solubilize up to respective 4.3, 9.4, and 13.5 molecules of water per surfactant molecule respectively.

实验表明， DAA， DAP和DAB的反胶束对水的饱和增溶能力，分别相当于每一个表面活性分子增溶4.2， 9.4和13.5个水分子。

Hoffman-Lauritzen theory was used to analyze spherulitic growth kinetics and the free energy of the folding surface was derived.

由此可见，PEG链段对胶束的影响越小，PCL嵌段的影响越大，越趋向于形成片状晶体结构。

The result shows that: the extraction of petroleum ether, polysaccharide and sodium copper chlorophyllin from banana leaves perform higher spumescence ability and foam stability. The critical concentration form pastern namely CMC and the surface tension in this concentration are 1.0 g/l (34.295 mN/m), 1.0 g/l (42.398 mN/m), 3.0 g/l (40.123 mN/m) respectively, which the value is close or excess the reference samples. The emulsify capability of the extraction of petroleum ether is the best in these active ingredients, and close to the emulsify capability of Tween-80. The emulsify capability of polysaccharide and sodium copper chlorophyllin from banana leaves are follow then.

试验结果表明：香蕉叶石油醚抽出物、叶多糖和叶绿素铜钠盐具有良好的起泡性和稳泡性；其临界胶束浓度CMC值和其该浓度下的表面张力分别为：1.0g/l（34.295 mN/m），1.0g/l（42.398 mN/m），3.0g/l（40.123 mN/m），已经接近或超过参照物的表面活性；香蕉叶石油醚抽出物的乳化能力最强，乳化性能已接近乳化剂吐温-80，其次为叶多糖和叶绿素铜钠盐。

Reverse micelles system was formed by sulphosuccinic acid his (2-ethylhexyl) ester sodium salt isooctane and KCl buffer solution.

采用由AOT（琥珀酸二（2-乙基己基）酯磺酸钠）－异辛烷－KCl缓冲液组成的反胶束体系，联合酶解技术提取脱脂小麦胚芽蛋白。

At the same time, the intensity ratio of the ICT fluorescence to the LE fluorescence, I〓/I〓, shows a "bell"-shaped variation with increasing CTAB concentration The intensity ratio was found to level off after the CMC of CTAB Together with the data from UV-Vis absorption spectroscopy, electric conductance measurements and the control experiments with tetramethylammonium bromide, it was concluded that the"bell"-shaped variation in the intensity ratio before CMC is due to the formation of premicelle aggregates consisting of ICT fluorophore and CTAB.

此时，ICT荧光强度与LE荧光强度之比，I〓/I〓随CTAB浓度增大而呈&钟形&变化。当CTAB浓度高于CMC时，I〓/I〓为一常数。根据紫外-可见吸收光谱，电导以及四甲基溴化铵对照实验的结果可知，当CTAB浓度低于其CMC时，I〓/I〓的&钟形&变化是由于长链对二烷基氨基苯甲酸与CTAB组成的胶束前簇集体形成所致。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
