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。

Both questions have troubled "two realm" philosophers—or dualists to give them their more usual name—, but the former has troubled them more, since modern physics is founded on principles that assert the conservation of various physical quantities. If a non-physical event causes a change in the physical world—dualists are repeatedly asked—, does that not imply that physical quantities like energy or momentum fail to be conserved in any physically closed causal system in which that change occurs?

所有这些问题困扰着二元论的哲学家，但是前一个问题更麻烦些，因为现代物理学坚持多种物理量的守恒原理，二元论者就会反复追问：如果一个非物理事件导致了物理世界的变化，那么，这不是就导出物理量不会守恒（而这是在物理上封闭的因果系统所会发生的）？

The eukaryotic translation initiation factor 5A (eIF-5A) is a small acidic protein (18k Da), widely presents in all organisms from archebacteria to mammals but not in eubacteria, with highly conserved sequences. eIF5A is unique in that it is the only protein known to contain the unusual amino acid residue hypusine (hydroxyputrescine-lysine), which is essential for eIF5A function and is formed by post-translational modification of a specific lysine residue.

真核生物翻译起始因子5A(eIF5A)是一个分子量约18 kDa的酸性蛋白，其序列从古细菌到哺乳动物高度保守，并广泛存在于各种真核生物细胞中。eIF5A是迄今为止唯一一种已知含有特殊氨基酸残基hypusine的蛋白质。hypusine是一种蛋白翻译后修饰产物，它的形成对eIF5A的功能完整至关重要，相关的研究结果表明hypsine在控制细胞周期循环的过程当中扮演着一个重要的角色。
