In this thesis,we try to theoretically and experimentally investigate quantuminterference in atomic multi-level system and atom-molecule hybrid system to findthe conditions for generating quantum interference,the constructive or destructivefeature of interference,and the dependence of quantum interference on theenvironmental conditions.

本文旨在从理论和实验两方面对以往较少涉及的原子及原子—分子混合体系中多能级系统量子干涉效应进行研究，并着重探索量子干涉产生的条件、干涉相长或相消特性及其对外界条件的依赖关系等。

Quantum genetic algorithm is a probability optimization method which is based on quantum compute principle. The precision and the rate of convergence are impacted by rotation angle.

量子遗传算法是基于量子计算原理的概率优化方法，在量子门更新过程中，旋转角的大小直接影响优化的结果和进化的速度。

At the same time, theories on the construction of the generalized coherent states and realization of coset space respresentation are briefly summarized, while the concepts of quantum phase space and the classical analogy for a quantum system are derived.

同时，对一般相干态的构造理论以及陪集表象表示的实现也进行了简要的介绍，并且引入了量子相空间和量子系统的经典类比等概念。

Atomic force microscopy is used to examine the surface morphology of the 3-monolayer InAs. It's found that the evolution of surface morphology with increasing the GaAsSb thickness can be classified into 3 stages: random distribution of InAs quantum dots, space-selective growth of InAs quantum dots on cross-hatching surface, and purely cross-hatching surface.

最后，由原子力显微镜分析，让我们观察到样品表面的InAs奈米结构的分布型态：(1)随机分布，(2)在田埂状(cross-hatching)的表面上选择性的成长，(3)奈米结构渐渐地消失，最后仅剩田埂状的表面型态。

In addition, the existing of quantum non-cloning theory leads to the birth of quantum cryptograph.

再者，由量子态不可克隆的特性产生了量子密码学。

In Chapter Ⅱ, the author mainly introduces the theory of quantum cryptography and the study of quantum characteristics.

在第二章，主要介绍了量子密码学相关的理论及量子固有特性的研究。

China and South Korea have excoriated Japan over its approval of new school books which they say whitewash the atrocities committed during Japanese occupation, and anti-Japanese protests have been held in Chinese cities. The lingering bitterness over Japan's past imperialism still threatens to mar relations between the big East Asian powers

中国和韩国强烈谴责日本通过新的中学历史教科书，他们认为这一教科书掩盖了日本在其占领期间所犯下的残酷暴行，反日抗议活动在中国数座城市发生，历史上日本帝国主义制造的痛楚无法被忘却，这有可能破坏东亚强国间的关系。
