This paper compares conditional entropy of entanglement and concurrence at the same condition,and the result shows that the curves of their evolvements are identical.

应用条件熵纠缠度研究了真空腔场中两全同二能级原子之间纯态和一类混合态纠缠的时间演化，比较了相同条件下两全同原子系统concurrence纠缠度的时间演化。

Configurational isomerism is then due to the presence in the molecule of one or more dissymmetric centres ,in the simplest case asymmetric carbon atoms ,each of which can have and absolute configuration; and ,or ,to the presence of double blonds which can give cis- and trans-geometrical isomers .

构型异构是由于分子中存在一个或一个以上的不对称中心，在最简单的情况下是不对称碳原子，每个不对称碳原子的绝对构型是和；或者，如果存在双键的话，那么将给出顺式和反式几何异构体。

Based on the structural theory of general systems this paper sets forth a general mathematical model of material levels which include atoms molecules and molecular congeries .

微观还原论无法揭示物质涌现性的根源，以及物质结构与性质之间的相互关系，基于一般系统结构理论，建立了物质在原子，原子基团，分子和分子聚集体等层次上的统一的数学模型，即物质系统结构模型，通过对该模型的数学分析，研究了环境与物质结构，物质行为，物质状态之间的相互关系。

According to the theory of a to ms all elements consist of a to ms.

根据原子理论，所有的元素都是由原子所组成的。

The results show that they relate to the dipole-dipole coupling strength between two atoms and atom-field coupling constant and nonlinear coefficient of field.

结果表明，它们与原子间的偶极相互作用、原子和光场的耦合系数以及非线性耦合系数有关。

And the influence of the ratio of the two atom-field coupling constants on sudden death of entanglement is discussed.

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。

A computed method of the bond formation power between atoms in crystal was presented with combination of both Yu′s "The empirical electron theory of solids and molecules" and Pauling′s covalence bond theory.

将固体与分子经验电子理论和 Pauling 共价键理论相结合，提出了计算晶体原子间成键能力的方法，并计算出常用的3 种触媒 Fe， Co， Ni原子间的成键能力分别为 2911 1， 2955 3， 2956 4。

Cupper atom is formed by means of the decomposition of CuBr into Cu;++, and then recombination of Cu;++. Consequently the recombination coefficient is bigger and the delay time of laser pulse gets longer when the working temperature is lower.

由于工作物质铜原子是通过分解CuBr成为铜离子，再由铜离子复合成铜原子，故工作温度较低时，复合系数较大，造成激光脉冲的延时时间变长，而当工作温度较高时，复合系数变小，使激光脉冲提前。
