In this dissertation, the ion-trapping, fastbeam-ion instability and electron cloud effect in BEPC and BTCF are studied indetail.

本文对北京正负电子对撞机上的离子俘获、北京τ—粲工厂上的离子俘获和快束流-离子不稳定性、BEPC上的电子云效应都作了比较细致的研究。

I clearly under- stand that pellet is an atomic nucleus, but the small light spot is an electron cloud.

我清楚地明白，那小球就是原子核，而小亮斑则是电子云。

In case the electron transfer increases the outer electron cloud density of active metal, metal catalyst would be liable to be poisoned by sulfur.

如果这种电子转移的结果使活性金属的电子云密度增加，则金属型催化剂抗硫性就会下降。

Furthermore, the specificity of certain reactions of electronic structure might be exploited to reconstruct the motion of the atomic electron cloud.

此外，某种电子结构反应之特定性，可以被利用来重建原子电子云之动作。

The functional groups which are placed at 4-position of pyridine-2,6-dicarboxylic acid can effect the electron cloud of the lanthanide complexes.

吡啶-2，6-二甲酸的4位取代官能团能影响配合物的电子云形状，配合物的荧光性能和电子能量传递密切相关。

The results show that the influences of the central atoms on electron cloud, electrostatic potential, total density of states are not clear. But the central atom can affect the components of the frontier orbitals HOMO and LUMO.

结果表明，中心原子对Keggin结构杂多阴离子的电子云、静电势、总态密度的分布影响不明显；但中心原子不同，前线轨道HOMO， LUMO的组成有一定差异。

The urban inhabitants distribution models consist of gravitation model, probatility model and simulating electron cloud model. The model system of urban inhabitants distribution was set up by two stages of distributing.

在人口分布模型中，创建了引力模型、概率模型和模拟电子云模型，并使用了两步式居民分布方法，形成了开发区居民分布模型体系。

Squeege business card printing and membership card, produced by atomiccenter around the electron cloud is in a relatively stable state, but even if the business card printing and membership card making is slow, when squeege, the atomiccenter worldaround e will be left in an unstable state, our e-pressurs in squeege, generate electrostatic free, therefore, only when the squeege business card printing and membership card at the same time making the squeege pressure fit in order to avoid the emergence of static electricity.

刮板制卡和会员卡制作的速度降低，原子核周围的电子云处于相对稳定的状态，但是即使制卡和会员卡制作速度变慢，刮板压力过大时，原子核周围的电子也会处于不稳定状态，电子会在刮板压力下游离出来，产生静电，因此，只有当刮板制卡和会员卡制作速度慢，同时刮板压力适合的情况下，才能避免静电的产生。

This paper researches a optical sensor and a new method for product oil identification and mixed oil distinguish and calculates the light intensity of the Fresnel reflection occurred at the interface between the product oil and a measuring probe. The product oil and oil mixtures are analyzed by using the principle of energy conservation and the inductor model of an electron cloud.

通过分析光的变化磁场的电磁感应对介质的作用以及光在介质分子间能量传递过程建立的电子云导体模型，运用能量守恒原理对光在介质中的传播以及折射现象进行了研究，对不同成品油及其混油的折射率进行测量及相关计算，得到了计算成品油折射率和识别混油的方法。

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。
