In this paper, the surface tension in four types of surfactant solutions, such as SAS, 1631, CAB-35 and JFCS in different concentrations were tested by using automatic surface tensiometer and the critical micelle concentration of each surfactant solution was determined which could be used as the mixing concentration of four types of surfactant solutions and the experiments of effective simulation of dust-settling by spraying them in fully mechanized caving face were carried out.

应用全自动表面张力仪对SAS、1631、CAB-35和JFCS 4种表面活性剂溶液不同浓度下的表面张力进行了测试，确定其临界胶束浓度，并以此浓度作为4种表面活性剂溶液的配比浓度；对4种表面活性剂溶液进行了综放工作面喷雾降尘有效性模拟实验，实验结果表明，所选取用4种表面活性剂溶液降尘效率均比清水有较大提高，对呼尘的降尘效率皆在90%以上；表面张力较小是选定综放工作表面活性剂溶液的重要标准，但非唯一标准。

Its hydrophilic groups is the inside carbonyl and amine base, and its lipophilic groups is the inside hydrocarbon chain and outer methyl. PAMAM of integral generation basically has not the surface activity. Its reason is that its outer groups is acylamino groups having very strong hydrophilicity so as not to reduce the surface tension of water. PAMAM different from traditional surfactant, have not critical micelle concentration, and exist in the form of "unimolecule micelle" in water.

结果表明：半代的PAMAM水溶液的表面活性与其分子具有两亲结构有关，亲水基团是内部的羰基和胺基，亲油基团是内部的碳氢链和外层的甲基；整代的PAMAM水溶液基本上没有表面活性，其原因是其最外层基团是酰胺基，亲水性很强，不能降低水的表面张力；树状大分子与传统的表面活性剂不同，不存在临界胶束浓度，在水中是以&单分子胶束&形式存在。

This paper mainly studied the synthesis and characterization of some dissymmetric bis-quaternary ammonium gemini surfactants, then determined the surface tensions of their water solutions, finally calculated their critical micelle concentrations and build a surface tension-concentration model.

本文主要研究了非对称型季铵盐双子表面活性剂的合成与表征，测定了其水溶液的表面张力，并计算出其临界胶束浓度。

Paper surface properties, like smoothness, hydroscopicity, and surface tension, cards and membership cards to make the wall of blood products.

纸张表面属性，象平滑度，吸湿性，牢度和表面张力，对制卡和会员卡制作品的光滑度影响很大。

Because of its low surface tension and surface energy, various waterproof agentscan be prepared from organosilicon.

由于有机硅的低表面张力和低表面能，它可以形成各种防水剂，和基体发生化学反应后，在物质表面形成透气防水膜。

The adsorption of polyoxyethylene alkyl ether surfactants (Brij 30 and Brij 35) on synthetic smectite clay nanoparticles and the interactions between them have been investigated through surface tension, zeta potential and rheology properties measurements, showing that Brij 30 and Brij 35 are adsorbed onto Laponite surface, and the adsorption is increased with decreasing oxyethyl groups.

通过表面张力、Zeta电位和流变学参数的测定，研究了聚氧乙烯烷基醚类非离子型表面活性剂(Brij 30和Brij 35)在合成锂皂石纳米颗粒表面的吸附及对Laponite水分散体系中颗粒间相互作用和体系粘度的影响。结果表明，这类表面活性剂能显著地吸附在Laponite颗粒表面上，且吸附量随其分子中POE链长短而不同。

Because of little and not well-distributed suction power of gas molecule to liquid molecule, there is surface tension between the liquid and gas in alveoli(a kind of suction power or concentric force souced from surface).

肺泡内液气界面存在着表面张力（一种表面能来源与分子间的吸引力或内聚力），是由于气体分子对肺泡内面表面液气分子吸引力很小，液体分子各向受力不匀的表现。

As for the drop-shaped pearl is because when the water can not be attached to the lotus leaf surface, due to the role of the surface tension of water molecules to make water droplets unite into a ball.

至于下降形珍珠，是因为当水不能附加到荷叶表面，由于水分子的表面张力的作用，使水滴凝聚成一个球。

Surface tension Surface force restraining a liquid, normally measured in dynes/cm2

热喷墨 按需喷墨的科技，墨水被飞快地加热成为一个气泡，并且喷出墨滴
