活性剂

In this way, much potential interference may be avoided in the determination of these drugs in biological materials and hemanalysis. These methods are rapid, simple and wider linear range, and can be used for determining procaine hydrochloride, dapsone and ampicillin sodium in injectin solutions of these drugs. The results obtained by these methods agreed with those by the official methods.A sensitive and selective method for the determination of dopamine was studied.

在此反应的基础上，实验(来源：6aABC论文网www.abclunwen.com)了pH值、表面活性剂、有机溶剂、加热时间、放置时间及干扰离子对测定的影响，所建立的方法具有线性范围宽，稳定性好等特点，可成功地用于相关药品含量的测定，与药典方法对照，结果吻合。

Frequently used additives are: curing agent, surfactants, Defoamers, desiccants, adhesives, wettibility dispersing agents and other additives, etc.

经常使用的助剂有：固化剂、表面活性剂、消泡剂、干燥剂、助粘剂、润湿分散剂和其他助剂等。

Results of the studies have comfirmed that surfactants cause the NAPLs to desorb from soil strongly and enhances the transferability of NAPLs through soil by improving their dissolution in liquid and fluid ability in soil. So the efficiency of pump-treat method can be improved by the surfactants.

大量研究表明，表面活性剂能促进NAPLs从土壤颗粒中解吸，并通过增溶和增流作用改善NAPLs在土壤中的溶解和迁移能力，进而提高抽出处理法的去除效率。

As a result, these detergents are all amphipathic, capable of interacting with both water and lipid.

表面活性剂通常是两性的，既能和水作用也能和脂作用。

Development of detergents has required optimization of the surfactants structure.

发展洗涤剂时，要求使用最恰当的表面活性剂结构。

We want to buy Intermediates, Surfactants, Emollients, Emulsifyers

我们要采购中间物，表面活性剂，软化剂

In order to stabilize the emulations, surfactants are added.

为了使乳剂具有稳定性，需要添加表面活性剂。

In this study, the binder compositions are fixed and effect of surfactant on the rheological behavior of alumina feedstocks is investigated.

本研究旨在探讨界面活性剂在其他黏结剂系统固定下，其对氧化铝塑料流变性质的影响。

The results show that glycerol, as surfactant, with a concentration of I % can alternate the interfacial tension between water and oil to some extent; thusly, the conglomeration problem can be inhibited during the microencapsulation process. Meanwhile, by controlling the reaction rate of condensation polymerization and adjusting the pH of the system, the floccules can be restrained effectively, and microcapsules with smooth surfaces are obtained. Finally, the addition of NH4Cl may result in properly strengthened microcapsules to resist the collapse during nature drying.

结果表明：采用质量分数为1%甘油做表面活性剂，可适当调节油／水界面张力，抑制微胶囊化过程中的黏结团聚；通过调节体系pH值，控制缩聚反应速率，可有效抑制水相中絮状树脂的产生，得到表面光滑的微胶囊；采用氯化铵作固化剂对微胶囊进行固化，可有效提高微胶囊的机械强度，得到在自然干燥后不破裂的微胶囊。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
