However, for the (3×3) arrays, the charge density overlap disappears.

最后，我们对比研究了Nb_4团簇在不同表面上吸附的特性。

So we can use ab initio method and DFT to describe electronic structure of molecule and atomic group. Using Dewar,Chatt, and Duncansons model can count out the interaction energy between molecular orbit and metal state.

我们利用从头计算法和密度泛函方法描述分子以及原子团簇的电子结构，采用Dewar，Chatt，和Duncanson模型可计算出分子轨道与金属态的相互作用能。

These stochastic bursting patterns are reproduced and explained by adding the term of noise to Chay model and the constructed map.

通过在Chay模型和构造的不连续映射中添加噪声项可以重复并且解释实验中的随机簇放电模式。

The experiments of neuronal pacemaker show typical bifurcations from period 1 to period 5 with stochastic bursting patterns. A discontinuous map of the slow variable in Chay model which captures the essential characters of the period-adding bifurcation scenario is constructed in this thesis.

在神经起步点实验中展示了伴有随机簇放电的从周期1到周期5的典型分岔，本文在把握加周期分岔的根本特征的基础上构造了Chay模型中慢变量的不连续映射。

In this paper, the chemisorption of energetic C〓 and C〓 clusters on diamond (001)-(2×1) surface was investigated by molecular dynamics simulation.

本文，研究了荷能的C〓和环状C〓团簇在金刚石（001）-（2×1）表面的化学吸附过程。

The chemisorption of CO on platinum clusters was treated by EHMO method.

本文用EHMO方法对CO在Pt原子簇上的化学吸附进行了量子化学计算。

The research on N_4 to N60 have been also stated in this study. Gas reaction method, liquid electrolyzing method and Chemosynthesis method have been used to synthesize polynitrogen clusters and find the optimal reaction conditions in this paper.

本文综述了高能密度材料的发展历史、性能特征以及应用前景，并总结了人们在实验和理论两方面关于N_4到N_(60)的各种可能稳定存在的氮原子簇的研究成果。

Densely tufted perennial chickweed of north ''.

And because it is brand new, the odor of oil paint is positive and indomitable, just like the feeling of chillness, neatness and prosperity when celebrating the New Year in a new house.

油漆的气味，因为簇崭新，所以是积极奋发的，仿佛在新房子里过新年，清冷、干净，兴旺。

In the asymmetric hydrogenation of ethyl pyruvate catalyzed by 0 5% Rh/PVP TiO 2, the chiral modifier cinchonidine not only induces the enantioselectivity, but also accelerates the reaction rate greatly.

研究了辛可尼定作手性修饰剂修饰的负载型纳米铑簇合物催化剂(0 5 %Rh/PVP TiO2 )催化丙酮酸乙酯不对称氢化反应，在该反应中手性修饰剂辛可尼定不仅具有对产物生成的手性诱导作用，而且对反应具有明显加速作用；在优化反应条件后，反应的TOF和对映选择性分别可以达到 5 8 0min-1和

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
