Alignment Chart is commonly used to determine the effective length factor of prismatic member.

一般在实务设计中均匀断面构件求取有效长度系数K最普遍采用的方法就是利用准线图，但对於应用准线图求取非均匀断面构件之有效长度系数Kγ，则受到相当的限制，故工程单位也常因此在设计时舍弃非均匀断面构件的考量。

The article is about the practice and theory of French landscape architect and artist Bernard Lassus. He has studied painting, absorbing alimentation from painting, and accordingly gained the new design elements. So his works are artistic. He pays more attention to the historical factor. He also emphasizes the creativity of space and the relationship of landscape and people in the space.

摘 要：简要介绍法国风景园林设计大师和艺术家伯纳德·拉索斯设计的实践和理论，他曾学习研究过绘画，从绘画的语言中吸取养料，从而获得新的设计语汇，所以，作品富有艺术性，注重场地的历史因素、空间的创造和场地中人与景观的关系。

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。
