The formation situation of the bond for metallocarboranes and metalloboranes is analyses with the bond valence formula for atomic cluster compound.

运用原子簇化合物键价公式，对金属碳硼烷和金属硼烷进行了成键情况分析，提出了碳硼金属三中心键和硼硼金属三中心键的概念，并指出了簇合物型、夹心型和多层夹心型金属碳硼烷的稳定存在主要是形成金属三中心键的缘故

Experimental results show that the size of cluster and laser absorption efficiency are strongly dependent on several factors,such as the working pressure of pulse valve,atomic number Z of the gas.

实验结果表明，脉冲阀门的工作压力、所使用的气体种类等因素对团簇的尺寸及团簇对激光的吸收影响很大。

This is due to the weaker orbital interaction between silver and CO, which is caused by larger atomic radius of silver atom.

然而，银团簇和一氧化碳分子的相互作用与早前研究过的金团簇和一氧化碳的作用相比要明显的弱了很多。

As a result, a way based on the atomicity density is developed for estimating and understanding the inhomogeneous structure at nanometer scale in the work.

由于目前对于离子液体的团簇结构没有明确的定义，因此本文提出了一种基于原子数密度的团簇评价标准。

Vampa took this wild road , which , enclosed between two ridges , and shadowed by the tufted umbrage of the pines , seemed , but for the difficulties of its descent , that path to avernus of which virgil speaks

万帕顺着这条荒僻的路走着，两边都是山岭，山坡上东一簇西一簇地长着松树，但看来这些松树似乎很难于繁殖，这条路倒象是维吉尔所说的通到阴曹地府去的火山口。

万帕顺着这条荒僻的路走着，两边都是山岭，山坡上东一簇西一簇地长着松树，但看来这些松树似乎很难于繁殖，这条路倒象是维吉尔所说的通到阴曹地府去的火山口。

I looked up to see a cute, baby-faced boy, his pale blond hair carefully gelled into orderly spikes, smiling at me in a friendly way.

我抬眼一看，只见一张可爱的娃娃脸，正友好地冲着我微笑，他浅黄色的头发用发胶整整齐齐地定成了一簇一簇的。

The relationship of the size of titanium clusters with electron affinities and that with binding energy have been studied.

本文研究了钦团簇的电子亲合能、结合能与团簇尺寸的变化关系。

The density function theory B3LYP method with LANL2DZ basic sets is adopted to opt all possible geometrical structures of Tin (n=2~7) and to get the most stable structure. Then, the binding energy and Natural bond orbital of Ti clusters are calculated and discussed.

利用密度泛函理论中的B3LYP方法，选择LANL2DZ基组优化Tin(2~7)团簇得到各团簇的稳定结构，然后对稳定结构的束缚能及自然轨道进行分析。

This thesis is mainly about the research on the synthesis, structures and reactivity of di-or tri-metal bridging carbene and bridging carbyne complexes

过渡金属桥卡宾和桥卡拜络合物本身即为简单的金属原子簇化合物或是合成金属原子簇化合物的重要前体，在有机合成和烯炔烃的聚合和异构化等催化反应中有广阔的应用前景以及在某些过渡金属参与的反应的机理研究中具有重要的研究价值。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
