An ionic bond is characterized by the transfer of an electron from one atom to the other.

离子键的特点是一个电子可以从一个原子转移到另一个原子。

There are many factors that determine the ionic bond and covalent bond. What kind of chemical bond is formed between two atoms does not only have connections to the atom itself.It is related to the price attitude of the iton.

决定离子键、共价键的因素比较多，两原子之间形成哪种类型化学键不仅与原子本身性质有关，还与形成的化合物中离子的价态有关。

Covalent bond, ionic bond, metallic interaction and Van der Waals force. Different potentials can be constructed according to the different interactions. For different types of phenomena of some interaction, different potentials can also be constructed. So, a great variety of potentials can be found in literature.

可依据不同类型的相互作用如共价键、离子键、金属键和Van der Waals力等构建不同类型的原子间相互作用势，而且同一类型的相互作用也因所处理的性质或过程(如体积、表面、团簇、缺陷等)不同所采用的形式也不相同，这样就构建了大量的各种形式的原子间相互作用势。

Recombination radiation can ionize another atom of the same species.

复合过程产生的辐射可能使同一原子核素的另一个原子发生电离。

The numerical simulation demonstrates that when the intensity of the driving laser is over-saturated,the atom will be ionized rapidly during a few optical cycles,this will lead to a continuous multi-plateau structure in the cutoff region of the high harmonics spectrum from the neutral atom.

通过计算机数值模拟，发现当激光场的强度超过饱和光强时，原子将会在几个光周期内被迅速电离，使得原子的高次谐波谱在截止区呈现出平滑的多平台结构。同时，在高频波段离子产生的高次谐波的影响将变得十分显著。

Atomic implies indivisibility and irreducibility, so an atomic operationmust be performed entirely or not performed at all.

这里"原子"的意思是看不见和不可分，因此原子操作要么必须全部做完，要么一点也不做。

Isomorphous substitution of heteroatoms, especially transition metals for Si or Al in zeolite frameworks is an important way to modify the zeolite properties for practical applications, which has achieved considerable interest in the field of zeolite chemistry.

近年来，杂原子分子筛的研究受到普遍关注。杂原子引入分子筛不仅可以有效地调变分子筛的结构和表面性质、赋予分子筛新的催化性能，而且可能得到新型的分子筛材料。

By means of X-ray diffraction, nitrogen adsorption, UV-Vis diffuse reflectance, a successful isomorphous substitution of titanium in the silica framework of SBA-15 samples with Si/Ti = 50, 25, 20 has been proved, the substitution of Ti for Si does not change the highly ordered two-dimensional hexagonal mesostructure of SBA-15. Titanium is totally tetrahedral and highly dispersed.

通过X射线衍射、N2气吸附脱附、紫外—可见漫反射等表征手段，证明在Si/Ti＝50，25，20时，钛原子成功地取代了SBA-15中的硅原子而没有改变SBA-15高度有序的介孔二维六角结构，其中钛全部以四配位状态存在，而且高度分散。

Coincidentally and almost simultaneously, a very similar atomic theory was posed in Indian Jainist philosophy; later Vaiseshika shcool of Hinduism also taught an atomistic theory of physics.

巧合的是，一种非常相似的原子理论几乎同时出现在印度耆那教哲学中；后来，在印度教的吠世史迦学派的学校中也在教授一种原子论的物理。

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。
