To the properties of the surfactant, such as surfactant chain length,solution chemistry and micellar solubilization of trimethylbenzene.

与此机理相一致的是，表面活性剂的某些特性，如有机链的长度，溶液化学性质，三甲苯的胶束增溶作用与合成的介孔材料维数有密切联系。

A method was developed for the microdetermination of La based on the fluorometric quenching effect of DBSAF-SDS.

结果表明，在表面活性剂SDS存在下， La3 +与DBSAF生成络合物使DBSAF的荧光猝灭。

The results show that HBA_n (n=9,20,80) series have rather higher surface properties in comparison to their monomeric counterparts.

最后还用动态旋滴法分别测定和分析了HBA_n(n=9，20，80)三种表面活性剂的界面张力。

Specifications / physical data on the physical characteristics: Composition: propylene glycol monomethyl ether, surfactant, water, and other proprietary components.

规格/物理数据物理特征：成分：二丙二醇单甲醚，表面活性剂，水，其他专有成分。

First of all, a monophase microemulsion was prepared with Triton X-100 as surfactant, and the nitration of phenols by concentrated nitric acid in the systems was studied. The influence of the mass fraction of nitric acid, oil/water volume ratio, reaction temperature and other factors on the reaction conversion and selectivity was examined.

首先在非离子表面活性剂Triton X-100形成的单相微乳体系中，用浓硝酸对苯酚进行选择性硝化反应，研究了硝酸的质量分数、微乳中油/水比、反应温度等因素对反应转化率及硝化选择性的影响。

In this paper, a systematic study on the wetting capacity of sulfate of myristic acid monoethanolamide was made by the canvas sinkking method, through measuring the wetting time of MMS's solution under different concentration, different temperature and different degree of hardwater and comparing with three other surfactants.

对肉豆蔻酸单乙醇酰胺硫酸酯盐的润湿性能进行了系统研究，用帆布沉降法测定了MMS在不同温度、不同质量分数溶液、不同硬水度中的润湿性能，并与其他表面活性剂十二烷基硫酸酯盐、月桂醇醚硫酸酯盐、十二烷基苯磺酸盐进行了比较。

In this dissertation, the major innovative conclusions are as follows: 1. Three new methods were developed for separation and determination of some active compounds in several kinds of medicines with NACE.

在水相中加入表面活性剂和有机溶剂可使被分析物范围拓宽，但仍需要求分析物在水中有足够的溶解度，这就限定了分析对象的范围。

Then obtain heavy magnesium water solution, add interfacial active agent and ammonia to solution, via hydrothermal treatment and filtration washing, dry to gain nemaline magnesium hydroxide.

得到重镁水溶液，向溶液中加入表面活性剂和氨水，经过水热处理，过滤洗涤后、干燥得到纤维状氢氧化镁。

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。
