The electronic structures of cluster Fe8 with D6h symmetry and Fe15 with Oh sysmmetry have been studied by MS-X method..The results show that(1 the exchange splittings of the d-band and the magnetic moments of the Fe-atoms are different in the two clusters;(2)the change distribution in both clusters is not uniform,showing that the electrons are transferred from peripheral atoms to inner atoms,and the spin-directionof the electrons transferred is in accordance with the symmetric characteristics...

用MS-Xα方法研究了Fe8原子簇（具有D6h对称）和Fe15原子簇的电子结构，结果表明：（1）两种原子簇中的Fe原子磁矩及其d能带中的交换劈裂性质互不相同；（2）两类原子簇中的电荷分布不是均匀的，电荷倾向于从外围原子向内部原子上转移，并且被转移电子的自旋方向与原子簇的对称性质密切相关。

The result shows that the curve has a minimal energy of -67.160922 a.u. at R = 4.77 a0, which means that the Li9 cluster may be formed stably in the body-centred cubic structure.

结果显示曲线在R = 4.77 a0处有一极小值-67.160922 a.u。，这表明Li9团簇的体心立方结构是可能稳定存在的。

Firstly, this paper carries a deep research of K-means which is one of clustering analysis algorithms, and proposes an efficient clustering algorithm based upon vector space initial clustering and nearby cluster search, which is composed of the two sub algorithms SPIC and CANC.

本文首先对聚类分析方法中的K-means算法展开深入研究，提出了一种基于向量空间预聚类和邻近簇调整聚类的高效聚类算法，该算法由两个子算法部分构成：SPIC子算法和CANC子算法。

In this paper we address the question of the transition between autoionization that prevails in small molecules, and delayed ionization occurring in larger molecules or clusters. This transition is illustrated by autoionization of Na2 Rydberg states on one hand, delayed ionization in fullerene C60, and delayed detachment in small cluster anions on the other hand.

本文通过Na2的里德堡态的自电离，富勒烯C60的延迟电离，阴离子小团簇的延迟解离研究了在小分子中起主导作用的自电离和在大分子以及团簇中出现的延迟电离之间的转变过程。

The common stressors are long working houres, short of working rest or even none of rest , bad labor environments , irrational labor institution and contradictory of social circumstances.1.2 The analysis of occupational stress900 Female workers were sampled at random with cluster sampling based on AET analysis.

1.2 职业紧张水平的研究以进入AET分析的各工种工人为基础人群。用整群抽样的方法，随机抽取各分析工种在岗一年以上900名女工作为紧张水平的研究对象。利用OSI-R中的OSQ和PRQ问卷测试作业女工的紧张水平和应变能力。

Well spoken. The rocket that carried Yuri Gagarin into orbit was the A1, known as the Vostok rocket. Sokolov is said to be the man most responsible for the multi-engine cluster used in that rocket.

不错，把Yuri Gagarin送入轨道的是A1火箭，也就是被命名为Vostok的那个，其多引擎火箭发动机组据说就是由Sokolov主要负责的。
