Next, in the scheme for teleportation of an arbitrary multipartite GHZ-class state by one EPR pair, only one EPR pair and 3 classical bits are needed, which greatly lessens the oppressiveness of both quantum and classical channels. Then, in the scheme for deterministic, unilateral and controlled teleportation via cavity QED, Alice can determinately send her state to anyone of her agents, whereas the agents can not, with the channel being noiseless. What the agents can do is just to control the teleporting process, which enhance the security of the communication.Besides,based on the schemes discussed above,it is easy to see the character of an entangled state which can accomplish deterministic teleportation via cavity QED.

利用一个EPR对实现n-体类-GHZ态的量子隐形传态方案，整个通讯过程只需要一个EPR对和3 cbits的经典信息，大大节省了物理资源，缓解信道压力；利用非对称类-W态实现确定的单向受控量子隐形传态，在没有噪声的条件下，Alice可以将量子信息准确无误地发送给任一个客户，但每一个客户只能控制配合整个信息的传输过程，客户之间不能实现确定的信息传递，这样便保证了信息的安全性。

基于微观IBM理论，提出转动诱导出玻色子量子相变的一种可能途径：一旦原子核在受到高能激发或作快速旋转时，假如外界提供的能量足以使玻色子完成拆对顺排，则核处于集体相与单粒子态的共存相，其特征是出现较密集的能谱；假如能量不足以完成拆对或顺排，可能发生两种情况之一，当核旋转达到某个临界转动频率ω c时，或者一个高角动量的玻色子脱离"集体"而"游离"出来，或者发生一个高角动量的玻色子转变为一个低角动量的玻色子，核仍旧处于集体相；均会伴随出现光辐射，产生基态带的一条能级——相变信号。

The main contents are as follows.1 For the state control problem in closed quantum systems, according to the distance between states, the error between states and the average value of an imaginary mechanical quantity, three Lyapunov functions are chosen, respectively. The corresponding control law designs and the convergence analyses are studied. Especially, for the Lyapunov function based on the distance between states, a class of control laws that can solve the problem that an initial state is orthogonal to a goal state is designed. The convergence of the system is analyzed via LaSalle\'s principle and one method to find the largest invariant set of the closed loop system is proposed by linearizing the unitary evolution operator at the corresponding instants.

在这一背景下，本论文在指出研究量子系统控制的必要性、回顾量子系统控制理论和方法的研究现状的基础上，从控制理论的角度研究Lyapunov理论和最优控制理论对于封闭量子系统的应用以及开放系统中的若干问题，主要内容包含以下几个方面。1针对封闭量子系统中的状态控制问题，根据状态间的距离、状态间的偏差、一个虚拟力学量的均值，分别选择三种Lyapunov函数进行相应的控制律设计和收敛性分析。

鉴于国内已经有学者对国家豁免的问题进行了专门的论述，作者试图在研究对象和方法上有所创新，在研究对象上，作者勇于触及该领域最具争议的敏感问题。

Jean Bodin (1530-1596) is the political theorist in the sixteenth century. His contribution to the political thought is focused on his theory of state, especially on his theory of sovereignty. In this treatise, the author tries to explain his theory of state systematically, based on the former study. It will include the origin of state, conception of state, end of state, theory of sovereignty and so on .

16世纪法国政治思想家让·布丹（Jean Bodin 1530－1596）在西方政治思想史上的贡献主要集中在他的国家理论，尤其是他的国家主权理论中，本文则试图在总结前人研究成果的基础上，系统论述布丹的国家理论，包括国家的起源、国家的目的、国家主权理论和政体理论等，使其国家理论更加完整，并客观评价他在西方政治思想史上的地位。

By introducing the generating method and the expanding method,a complementary abstract state space can be constructed using the generating method on goal state once and the expanding method several times in turn.They are useful tools for designers to construct the complementary abstract state space in an easy way,where the complementarity of abstract states means that each ground state can only be represented by one abstract state and all the ground states can be represented by all the abstract states.

然后又提出了抽象状态空间的生成方法和扩展方法，从一个准确描述的的目标抽象状态开始，使用一次生成方法和多次扩展方法，可以让设计者很容易的得到一个规模适度的互补抽象状态空间，即每个基本状态只有一个抽象状态来表示，所有的抽象状态又能表示所有的基本状态。

It is suggested that TDS can be used as a new method for the analysis of pedogenesis and climatic change.

总之，热处理过程中磁化率的变化能非常灵敏地反映磁性矿物的转化情况，而且，这种转化往往与样品所经历的土壤化作用强度密切相关，因此，TDS可做为分析成土作用强度和古气候变化的一种新方法。

Therefore, in this chapter, I will research into the conflict and contradiction of the paternity. Also, in this novel, the father's behavior of "He who loves well chastises well." is quite suspicious, one of the reasons is that the father thought his son belonged to him. And then, this thesis quoted Lacan's theory to touch upon that someone who has accepted the concept of patriarchal society, he will be influenced for his whole life. That also reveals that human being has no choice sometimes in this society.

因此本章会先就父子关系的冲突与矛盾做深入的探讨，小说中的父亲似有对儿子爱之深责之切的行为，其原因可能在於父亲将儿子视为所有物所致；其次，论文将引用拉冈相关理论，讨论在父权社会中，不论身分为何，只要是已受父权社会观念根深蒂固影响的人物，终生都将受其所苦，此也揭示出人生存於社会上的无奈。
