The organic montmorillonite VC18-MMT was prepared by the exchanging inorganic cations with vinylbenzyldimethyloctadecylammionun chloride which could be co-polymerized with styrene.The predispersion of VC18-MMT was realized via sonicating the suspension of the montmorillonite particles in emulsifier solution,and then the styrene was added into the system and the in situ emulsion polymerization was carried out to prepare PS/VC18-MMT nanocomposites.

以可与苯乙烯发生共聚的阳离子表面活性剂乙烯苄基二甲基十八烷基氯化铵为插层处理剂改性蒙脱土（VC18-MMT），有机蒙脱土在超声波强剪切作用以及乳化剂作用下预分散在乳化剂溶液中，然后引入苯乙烯单体进行原位乳液聚合制备聚苯乙烯/蒙脱土纳米复合材料。

Commercial manufacturers will often use a low-molarity buffer so that the consumer can easily resuspend the conjugate in the buffer of his or her choice. Generally, high-salt buffers and surfactants should be omitted from the final storage buffer as they may cause damage by hydrolysis or displacement of the antibody.

最终储存用的缓冲液应避免使用高盐缓冲液和表面活性剂，因为它们可能水解或取代抗体。

The genus Rhodococcus is of considerable interest in recent years, stemming from their diverse applications in biodegradation, bioremediation, biotransformation and biosurfactant.

红球菌属在生物降解、生物修复、生物转化和生物表面活性剂等领域得到了日益广泛的应用。

在实验室用发烟浓硫酸对环烷基油进行磺化反应，合成了一种新型的三次采油用表面活性剂：环烷基石油磺酸盐。

Effects of initial pH,aeration rate,temperature,surface-active detergent,inducer and metal ions on laccase production from Trametes versicolor HS-03 were studied.

研究了培养基初始pH值、通气量、温度、表面活性剂、诱导剂、金属离子对云芝(Trametes versi-color)HS-03产漆酶发酵条件的影响。

The optimum conditions of synthesis were determined as follows:molar ratio of 2,4-di-t-amylphenol and anhydrous trimeric acetaldehyde 2∶1.2,amount of water 180 g,amount of emulsifier 0.5 g,and amount of catalyst 11.0 g at reacting temperature 80～83℃ for 5 h.

以2 ，4-二叔戊基苯酚、无水三聚乙醛为反应原料，采用含有表面活性剂、酸性催化剂的水作为反应溶剂，缩合反应合成2，2′-亚乙基双(4，6-二叔戊基苯酚)。

Optimization of the medium was carried out on the level of flask, corncob, tryptone, Mg2+ and Hisdidane were selected for the production of xylanase. Effects of other factors, such as Tween-80 on the production of xylanase were also ascertained. After the orthonagol design, the optimal medium for the production of xylanase on the level of flask was established.

在摇瓶水平上进行了培养基筛选实验，筛选到适合于木聚糖酶发酵主要碳源—玉米芯、主要氮源—蛋白胨、无机盐离子—Mg~(2+)、氨基酸—His，还进行了表面活性剂Tween—80的添加量等因素试验。

In the disposal process of surfactant wastewater, flocculation technology is usually used as a pretreatment method. The flocculation process of this kind of wastewater is very complicated because of its complicated components and unconstant characteristics.

在表面活性剂类废水的处理过程中，混凝工艺作为预处理手段经常被采用，但由于该类废水成分复杂、性质多变，使得其混凝过程也较为复杂。

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。

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。

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。
