However, as we know under present experimental conditions ultracold atoms injected into a cavity prefer to cluster, therefore, and it is very important to develop a many-atom mazer.

然而实际的实验情况并非如此，超冷原子会成团进入腔中，故此建立描述多原子微激射器的理论是非常有必要的。

There are two parts in this dissertation. In part one, the reaction scattering for the H〓 system is studied using three-dimensional quantum mechanical coupled channel distorted wave approximation.

本文分两部分：第一部分用三维量子力学耦合通道扭曲波方法研究了三氢系统的反应散射；第二部分提出了一种原子与双原子分子相互作用的。。。

The tin atom of the title molecule exists in a distorted- trigonal- bipyramidal geometry, defined by three carbon,one iodineand one oxygen atoms leading to a five - membered chelate ring. The x- ray analysis show tha...

标题化合物分子中的锡原子被配体的三个碳、一个碘和一个氧原子配位；配位原子是畸变的三角双锥构型；标题化合物具有与卤素发生取代反应而不发生加成反应的性质。

The universal formulases of a average internal energy of atom in metal and the two different kinds of metal atomic interaction potential have been derived by applying to the classical concept of the metalic structure and concerning the Gauss type ball symmetry of the around electronic density of atomic nucleus.

本文介绍了亚稳态Fe50Cu50固溶体晶格常数的测量结果，应用金属结构的经典概念并考虑到原子核周围电子密度的高斯型球对称分布，导出了计算金属中一个原子的平均内能和两种不同金属原子相互作用势的普遍公式。

Calculations indicate that Ni-Ni interaction in Ni81B19 alloy is stronger than metallic bond in pure Ni. However, the Ni-Ni interaction in pure Ni is stronger than that in Ni80P20 alloy. Direct B-B contact in Ni81B19 alloys appears in our simulation, however no direct P-P contact in Ni80P20 alloys is found.

其次，在Ni的d电子和B的p电子之间存在着强烈的相互作用，形成Ni原子和B原子间的强共价作用。B和P的加入后使催化反应中的活性位Ni的活性d电子数增加，在合金中起修饰作用。

The smaller metalloid atoms of the alloys might fit into holes in the dense random-packed structure of the larger metal atoms.

合金中非金属的小原子可能填进由大原子随机填塞形成的紧密结构中。

Lowenergy ion/surface interactions play an important and sometimes dominant role in controlling film microstructure and/or microchemistry.

近表面层的原子仍保持其原平面晶格构型，但受再构表面的影响，越近最表面层，原子在晶格平衡位上的热振动振幅越大。

The results show that the release of H and O atom and the burning of part carbon atoms in microcrystal,results in formation of the enrich micropores at the surface of PANACF.

形貌分析结果表明，因H、O原子等逸出及微晶间部分碳原子被烧损，PANACF的表面形成了极丰富的微孔。

The atom is placed in an oscillating uniform electric field. Find the induced dipole moment of the atom.

将原子放在震荡的均匀外场中，求原子的电偶极矩。

The expectation value of atom dipole moment is always zero, but the fluctuation of dipole moment is a constant and not zero during the atomic spontaneous emission.

在原子的自发辐射过程中，其偶极矩的期待值总是零，但偶极矩的涨落恒等于一个不为零的常量，因此原子的自发辐射是由真空起伏导致偶极矩的涨落引起的。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
