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。

The third part is to analyze the gender preference of peasants in village N, S and village B based on the data of fieldworks and SPSS. It is found that, without taking the birth control into consideration, son preference ratio of peasants in village N, S is 24% higher than that of village B. Suppose that only one child is allowed in one family, son preference ratio of peasants in village N, S is about 40% higher than that of village B.

研究发现，在不考虑胎次的情况下N、S两村农民的偏男系数比B村高24%，在假设只能生育一孩的情况下，N、S两村农民的偏男系数比B村高出将近40%；在生育行为方面，N、S两村农民明显偏好男孩，B村农民没有性别偏好；在孩子的抚育方面，N、S两村农民与B村农民没有显著性差异，均没有偏好男孩的表现。

So what I want to emphasize here is that there's not so much difference in Sony and Microsoft, for example, they both want dinner and Sony's dinner you only have once or twice a year, they're expecting that one special dinner, but Microsoft is expecting something a little more down to earth meaning once or twice every month. But the dinner itself is not different, the steak, you have the main course, the salad, these are the same. But maybe Sony has a little more fancy dessert, but the dinner itself is not much different amongst Microsoft and Sony in what they are expecting. So the battle between Microsoft and Sony will not be about the dinner but how much it will be or how much people are willing to pay for that amount or where can the people eat, and the number of restaurants. I think the battle lies there.

这里我要说的是S和M其实没什么太多的不同，比如他们都要举办晚宴，S一年有1到2次，他们期望的是一次特别的晚宴，而M希望的是每个月1到2次，但晚宴本身没什么区别，牛排、色拉，也许S会多些花式甜点，不过S和M所期望的结果是一样的，所以S和M之战取决于晚宴的价格或有多少人愿意为此付费，或者餐馆的数量。
