二苄基

Although these inhibitors including 19 compounds of benzylidene malononitrile family and 13 compounds of 3-substituted indolin-2-ones family, possess quite different structures,a common pharmacophore model with very good stratistical results was determined.

尽管亚苄基丙二腈化合物和3-取代吲哚啉-2-酮系列化合物具有完全不同的骨架结构，但得到的药效团却具有共同的特性，这表明当这两类抑制剂和受体发生相互作用时，采用了相似的结合模式。

Bromcresol burple - hexadecyldimethyl benzyl ammonium bromide spectrophotometry was used in the determination of anion surface active agent in wastewater from lotion industry or sewage.

The result of preliminary bioassay shows that the target compounds had obvious specificity to different bacteria at 0.1%, and had an inhibitory rate of 100% on Monilia albican and Escherichia coli.

抑菌测试结果表明，质量分数为0.1%时，N，N'-二（2-羟苄基）取代咪唑烷化合物对不同菌株的抑菌活性具有明显的特异性，对白色念珠菌、大肠杆菌的抑菌率达100%。

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。

In the aqueous solution, Cu precipitates with ammonium thiocyanate and tetradecyl benzyl dimethylammonium chloride .

研究发现，在水溶液中Cu与硫氰酸铵、氯化十四烷基二甲基苄基铵形成不溶于水的三元缔合物，在少量氯化钠存在下此三元缔合物沉淀浮于水相上层并与水分成界面清晰的两相，分相过程中Cu被定量浮选。

Now, however, all children continue in "comprehensive" schools, and the eleven-plus determines which courses of study the child will follow.

然而现在，所有的孩子都要在综合学校继续学习，所以这次考试只是决定他们将要学习哪些课程。

Cultivatable land , and led to a general recognition that development must not be carried at the cost of agriculture .

城区的迅速扩大在很多情况下侵占了宝贵的可耕地，使人们普遍认识到发展不能以牺牲农业为代价。
