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.

But when we face a series of works, then the whole exhibition made up of these works, we will feel more passive, for when we enter the exhibition space, we are surrounded by a mini-world. To some extent, we become captive and imprisoned; to put it another way, the physical sense of the series works is more powerful, and it indeed dominates the space to create a new space by its quantity and volume, the artist then seems play a role of a temporary 'creator'.

但是，当我们面对着系列组画，进而是以此构成的整个展览，我们的状态就被动得多，自我们进入到展览的空间，就已经被一座小世界包围，在某种程度上，我们成为了俘虏，和被囚者；换句话说，组画的物质感要强大得多，它实际掌控了空间，以它的数量和体积布置了一个新环境，而画家似乎扮演了一个临时的"造物主"角色。

The idea of a similar coherence underpinned Lévi-Strauss's magnum opus, the four-volume Mythologiques series, published between 1964 and 1971. Not unlike a latter-day Frazer revisiting the Golden Bough, he started out with the myths of the Bororo in central Brazil, gradually gaining in complexity and working northwards towards Oregon and British Columbia, and from there back to Brazil. He proceded by a kind of "semantic contagion", demonstrating how one myth implied and related to another through a series of parallels and contrasts.

类似的连贯性的想法为Lévi-Strauss的巨著打下了基础，那就是1964年至1971年出版的四部神话学系列，不像后来的Frazer再次访问Golden Bough，他一开始着手就使用巴西中部的Bororo的神话，这些神话复杂的情况下，在工作中从Oregon和British Columbia，再从那里返回巴西的过程中逐渐得到的，他接着以一种&语义传染&，演示如何将一个神话和相关的另一个相似之处通过一系列的对比联系在一起。

By employing the Jordan-Wigner transformation and a modified mean field method, we are able to determine its ground-state quantum phase diagram approximately. The chapter IV is the main part of this Thesis. It contains the main innovations in our work. We propose and study in detail a S=1 Ising chain with the interplay of single-ion anisotropy and dimerization. The main results and innovations are the following: We show that the total number of the zero-component of spins at each site is a conserved quantity. This quantity, which may intuitively called as hole's quantum number, is hidden in the system. We show further that the hole's number in the ground-state is zero; By using the Jordan-Wigner transformation, we map this model onto a series of subsystems described by the spin 1/2 dimerized transverse Ising model. We solve the subsystems exactly, by presenting the exact wave functions and spectra;We show that this system exhibits a series of quantum phase transitions by varying the dimerization strength. We determine the quantum critical points exactly. We also show that the criticality is the same as that of the uniform S = 1/2 transverse Ising chain.

第四章是本文的重点及主要创新内容，我们具体研究了自旋为1的在横向单离子晶格场中的一维二聚化Ising链，我们得到的主要结果和创新之处是：(1)证明了这一模型具有一种隐藏的对称性，即自旋第三分量为零的格点数目是一个守恒量，并证明基态出现在空穴数目为零的子空间中；(2)利用Jordan-Wigner 变换将此模型变换到一系列自旋为1/2的横磁场中的二聚化Ising 模型，并给出了相应严格的波函数及能谱；(3)我们发现系统的基态随着二聚化强度的变化将呈现出一系列量子相变，我们得到了量子临界点的精确位置，并证明其临界性质与自旋为1/2的横磁场中的均匀Ising 链中的临界行为属于同一普适类。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."
