In this paper, through a series of experiments, two series of quaternary-ammounium Gemini surfactants were synthesized, namely the pair alkylene double quaternary ammonium salt surfactant m-s-m·2Br and the pair the alkylene double quaternary ammonium salt surfactant -s-·2Br. We has carried on the attribute with the infrared spectrum to its structure, and to affected the factor which the synthesis pair the alkylene double quaternary ammonium salt surfactant responded to carry on the discussion. We has discovered the synthesis pair the ethylene double quaternary ammonium salt surfactant m-2-m·2Br optimum condition: The bromo alkane and a tetramethyl ethylene diamine mole of ratio is 3.0: 1.0, makes the solvent by the ethyl alcohol, 80℃ under responds for 48 hours in the backflow temperature; Synthesis pair alkylene double quaternary ammonium salt surfactant 12-S-12 ·2Br optimum condition: 12 tertiary amine and 1, 3- propylene dibromide (1, 4- two bromines butane) a mole of ratio is 2.2: 1.0, makes the solvent by the ethyl alcohol, responds for 48 hours in the constant temperature 80 ℃ under backflow.

本文通过一系列的实验，合成了两个系列的Gemini型表面活性剂，即双烷撑双季铵盐表面活性剂m-s-m·2Br和双烷撑双季铵盐表面活性剂-s-·2Br，用红外光谱对其结构进行了表征，并且对影响合成双烷撑双季铵盐表面活性剂反应的因素进行了讨论，找出了合成双乙撑双季铵盐表面活性剂m-2-m·2Br的最佳条件：溴代烷与四甲基乙二胺的摩尔比为3.0：1.0，以乙醇作溶剂，在回流温度80℃下反应48小时；合成双烷撑双季铵盐表面活性剂12-s-12·2Br的最佳条件：十二叔胺与1，3-二溴丙烷(1，4-二溴丁烷)摩尔比为2.2：1.0，以乙醇作溶剂，在恒温80℃下回流反应48小时。

But when I saw a senior education, I can be very proud to tell you that I have no regrets today is Who leaves this determination to do so is she, an ordinary teacher, a bit ordinary private kindergarten teachers - teachers Twenty years ago since she labeled as "child king" crown, it is destined to accompany her with the ordinary, there is no substantial income, no enjoyment of luxury, there are only busy life and shoulder heavy responsibilities, in this extraordinary early childhood education position, has spent more than two dozen Spring and Autumn Annals, he no regrets, she "does not obliterate the heart of love," as a motto to inspire, and remind ourselves to constantly improve themselves. 20 years ago, a woman, in the absence of any conditions with the help of a man propped up this banner, what she has insisted this is love, love of children is a love of education, For many years, her rain or shine, as she said, so the teacher, I extraordinary, and so the teacher, I am rich, and so the teacher, I am happy, and so the teacher, I have no reason to regret this life.

但是当我看到了一位教育前辈时，我可以非常自豪的告诉大家，今天的我无怨无悔，是谁让这片嫩叶有如此的决心呢，是她，一位平凡的教师，一位平凡的民办幼儿教师--叶小英老师自从二十年前她戴上"孩子王"的桂冠后，就注定她要与平凡相伴，没有丰厚的收入，没有奢华的享受，有的只是生活的忙碌和肩头沉甸甸的责任，在这平凡的幼教岗位上，已度过了二十几个春秋，他无怨无悔，她以"不泯的童心眷眷的爱心，"作为座右铭来激励自己，鞭策自己，不断完善自己。20年前的一位女人，在没有任何条件的帮助下，一个人撑起了这面旗帜，是什么让她有这份坚持，是爱，是对孩子的爱，是对教育事业的爱，多少年来，她风雨无阻，就如她自己所说的一样，做老师，我平凡着，做老师，我富有着，做老师，我幸福着，做老师，我今生无悔。

All in all, we had made good progress for day 2 -- 25 of 34 pitches, with only 9 to go for day 3. Nonetheless, day 2 was the hardest. We flailed on the traverse.
