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。

Additionally, not wanting to insulate our directors from any corporate disaster we might have, we don't provide them with officers' and directors' liability insurance (an unorthodoxy that, not so incidentally, has saved our shareholders many millions of dollars over the years).

Any change we make in the composition of our board will not alter the way Charlie and I run 的，一位收入普通相当依赖董事酬劳，而且亟欲受邀担任其它公司董事以获取更多董事报酬的人，他很有可能不敢斗胆冒犯 CEO 或其它董事成员，因为后者对于前者在公司业界的名声有相当大的影响力，而如果管理当局相信高额金钱会影响到独立性，那么他们很有可能错过了一大群真正敢发出声音的人。
