Under the optimum conditions, the linear range of the method was 0-80 μg/L. The detection limit was 4.58×10^(-7) g /L.The catalytic reaction was the zeroth order one. The apparent activation energy and the reaction rate constant was found to be 96.04 kJ/mol and 3.61×10^(-3)/s, respectively. The sensitivity was increased by 3 times in the presence of surfactant.

Usage: The large amount of morpholine are used to produce rubber promoter, such as NOBS, OTOS, and MDS, vulcanized agent, such as DT-DM, Cleaning agent, filth-killer, antirust, anti-buraing, antiseptic, actine agent of surface, priating and dyeing, optics bleaching agent, optics plating liguids, antioxidizer, hydrolyfic agent, initator, dereloper, keep fruito fresh, deodorant, polishing compousd and, organic solvent. So, it is widely used in chemiced.

吗啉大量应用于制造橡胶促进剂（如NOBS， OTOS，和MDS等）、硫化剂、清洁剂、除垢剂、防锈剂、防焦剂、防腐剂、表面活性剂、纺织印染助剂、光学漂白剂、化学镀液、抗氧化剂、水解剂、引发剂、显影剂、水果保鲜剂、除臭剂、光亮抛光剂以及有机溶剂等，是用途极广的化学品。

Compared with the previous method, the improved route can provide directly a spheroid form of immobilized lipase particles of which the size can be controlled by adding non-ionic surfactants during the preparation process so as to increase the recovery rate of enzyme as well as decrease the external diffusional restriction which can diminish the enzyme activity. The improved method can also alter the hydrophobicity and microstructure of the immobilized enzyme matrix by changing the molar ratios of different alkoxyl silanes so as to enhance the enzyme activity by a"surface active effect"and eliminating the internal diffusional restriction.

与前人的制备方法相比，改进的方法可直接制得球形的固定化酶颗粒，而且颗粒的大小可以通过在制备过程中加入非离子型表面活性剂加以控制，从而可以提高固定化过程的酶活回收率和减小外扩散效应对酶的表观催化活力的影响；改进的方法还可以通过改变原料硅氧烷的种类及配比来改变最终制得的固定化载体的疏水性质及微观结构，从而通过对脂肪酶的&界面活化&作用和减小内扩散效应提高固定化脂肪酶的表观酯化活力。

Using p-xylene, different acyl chloride and alkylogen, six kinds of isomers were synthesized, with similar structure, carbons of same quantity, and the position of alkylaryl dissimilarity.

本文利用对二甲苯、不同碳数直链酰氯以及卤代烷合成出6种结构相似、长链烷烃碳数为12、芳基在烷烃链不同位置的烷基苯磺酸盐类表面活性剂。

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。
