吸附原子

It is concluded that the bonding between adsorbate and substrate copper atoms are approximately limited in the first surface layer.

可以认为，在Cu(100) 2~(1/2x22~(1/2)R45°-O的氧吸附表面结构下，吸附氧原子和衬底之间的结合主要来源于表面最外层铜原子与氧原子的相互作用。

Probably, during the formation of spherical Au nanocrystals, PVP or PAM can be selectively adsorb on certain crystal planes of Au nanocrystals by the complexing effect between N or O with Au atom, thus leading to the different growth rates at different crystal planes of spherical Au nanocrystals and resulting in the formation of faceted Au nanocrystals and Au nanoplates.

研究表明，多面体和片状Au纳米晶是由球形Au纳米晶转变而来，这个转变是由于在球形Au纳米晶的形成过程中，PVP和PAM借助于其特有的N原子和O原子吸附到Au纳米晶的Au原子上，造成了晶体不同晶面生长速率的差异而导致的结果。

It indicates that the N—O bonds in the singlet dimer adsorption configurations are weaker than any other structures, and this is propitious to the NO direct decomposition. 7. Unlike NO molecules interaction with copper atoms, when two NO molecules interact with the adjacent silver atoms, the non-planar structures are more stable than the planar.

同时，单重态的二聚体与相邻的金属铜和银原子作用时，由于电子从金属原子转移到二聚体上的数量最多，因此在这种吸附构型中，金属原子被离子化的倾向最大，同时使得二聚体中N—O键被削弱的程度也最大，有利于NO的直接分解； 7。

Based on theoretical calculation of electronegativity of groups offlotation-reagent and method of infra-red adsorption spectroscopy, the collection andadsorption of α-nitroso-β-naphthol in hematite flotation have been studied. The chemicaladsorption seems to be predominant owing to formation of pentacyclic nitrosyl chelate com-pound by atoms of nitrosyl bond in α-nitroso-β-naphthol together with Fe~(3+) on hematitesurface.

It is found that theadsorption of O2 around a Pb adatom is barrierlessly dissociative, with the dissociatedO atoms bonding with both the Pb adatom and surface Pb atoms.

我们发现，氧分子在Pb的adatom附近的吸附是直接的分解吸附，而且吸附能比在干净的Pb表面的吸附能大了1.48 eV/原子。

The invention is characterized in that the molecule of the polymer adsorption material has a structure in formula I: in the formula, R is selected from the natural polysaccharides with amino groups and hydroxyls and the derivatives thereof or the chemosynthetic polymers, the molecular weight of which is from 6 KD to 500 KD; X is selected from a C0 to C6 paraffinic chain with O atoms, N atoms or OH groups; R1, R2 and R3 are selected from a C1 to C4 alkyl group.

生物医学材料领域中的水溶性阳离子多聚物吸附材料及其应用，包括采用带有氨基或羟基的天然多糖及其衍生物或者化学合成多聚物季铵化反应合成，其特征在于该多聚物吸附材料分子具有式的结构：式中，R选自粘均分子量范围为6KD～500KD的带有氨基或羟基的天然多糖及其衍生物或者化学合成多聚物；X选自含有O原子、N原子或者OH基团的C 0 ～C 6 烷链；R 1 、R 2 、R 3 选自C 1 ～C 4 的烷基。

For the tetracene overlayer near to a monolayer, formation of a parquet-like pattern was observed.

当分子长轴取向垂直于[1-210]方向并且其质心位于密排原子列上两个Ru原子的短桥位时，该位置是它的次佳吸附位，在该位置的吸附能为4.19 eV。

That accounts forwhy Ga clusters occupy both the half unit cells of the 7×7 in thegrowth process.

初步的第一原理计算表明单个Ga原子吸附在7×7单胞的两半具有几乎相同的吸附能(差别仅为5meV)，这意味着Ga原子会随机地占据7×7单胞的任意一半成核生长，从而Ga团簇对7×7单胞不存在优先占据的特性。

Some representative atoms and molecules are selected to study the kinetic behavior of adsorption and diffusion on the flat and defective surfaces by employing five-parameter Morse potential and improved extended LEPS potential in this dissertation.

本论文选取了一些具有典型意义的原子和双原子分子通过5-参数Morse 势和改进推广的LEPS 势方法研究了原子、分子在过渡金属平坦和缺陷表面的吸附扩散的动力学行为。

The electron location function shows the electronic density changes at both the atomic vacancies and antisites. There is an obvious absence of electronic areas where the vacancy of Ga has the dangling bonds of N, which are favourable for the sdsorption of metal atoms. In contrast, at the vacancy of N, there is more electron distribution(ELF:0.16-0.45), forming lone electron pairs which are profitably available to combine electronegative atoms.

电子局域函数显示了表面空位和替位处的电子密度变化，表面Ga原子空缺处有非常明显的缺电子区域，悬挂键临近N的电子密度增大，有利于对金属原子的吸附；N原子空位处的ELF值为0.16-0.45，有利于同电负性较大的原子结合。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
