离子键

While in the case of system Ⅱ, hydrogen bonding is introduced into SAMs by the amide group.

当末端为氨基和磺酸基时，LB膜与基底间则以离子键的形式存在。

In addition, the 10 peptides are rich in basic amino acid residues and serine and threonine, it is likely that the peptides combine with iNOS FAD binding domain through formation of ionic bond and hydrogen bond.

因此，这些多肽很可能通过与iNOS的FAD结合区的酸性氨基酸形成离子键，以及通过丝氨酸或丝氨酸的醇羟基与酶分子的有关部位形成氢键而结合并起到抑制作用。

Scatchard analysis indicated that at least two different classes of recognition sites were formed during the course of self-assembly between monomers and templates through hydrogen bond or ionic bond.

Scatchard分析显示了功能单体甲基丙烯酸与模板分子阿替洛尔、美托洛尔在自组装过程中通过氢键和离子键形成了至少两类不等价的结合位点。

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。

FTIR and SEM analyses indicated that crosslinking reaction between Zn2 and NBR might occured during the curing process,and metallic bridge bond between them was formed.

傅里叶变换红外光谱和扫描电镜分析表明，在硫化过程中，Zn2与NBR发生了接枝和共交联反应，形成离子键桥键。

This implies that the atomic near neighbour distance of metallic bond solid solution is the closet to VCA model among the three solid solutions, although the vegard's law are not followed.

离子键固溶体中第一近邻距随成分的变化量只有近邻距Vegard定律变化量的40％左右，而共价键固溶体只有20％左右，金属键固溶体的变化量最大，一般都在50％以上，甚至高达80％左右。

This might be attributed to the ionic crosslinkage formed by multivalent ions.

这可能与高价离子形成的离子键交联有关。

The metal ions form ionic bonds, which are nondirectional, with oxygen atoms that previously had been bonded rigidly to specific Si atoms.

金属离子与氧原子形成无方向性的离子键，而氧原子之前一直牢固结合在特殊的硅原子上。

At the present time, It is a major method of research on the thermostability of thermozymes to compare the homology of amino acid sequence between thermozymes and mesophilic enzymes.

螺旋的稳定性使嗜热酶在二级结构上更稳定。在高级结构中，&额外&的离子键、疏水作用、氢键、寡聚体的形成等对嗜热酶的耐热性起主要作用。

The calculated results show that azido in azides has linear structure , the most optimized CaN6 has linear structure , and the most optimized (CaN6)n (n=2～5) clusters have chain structure of perpendicularity of approximate diamond composed by two azido with two Ca atoms . The middle N atoms of azido show positive, the N atoms at both ends of azido show negative, and the N atoms effected with Ca atoms directly show more negative . There is strong ionic bond between the Ca and N atoms. The IR spectra of the most optimized (CaN6)n (n=1～5) clusters have four vibrational sections , the whole strongest vibrational peak lies in 2195～2280cm-1,and the vibrational mode is anti-symmetric stretching vibration of N-N bonds in azido . Stability analysis show that (CaN6)3 and (CaN6)5 clusters are more stable than other clusters .

结果表明，叠氮化合物中叠氮基以直线型存在，CaN6团簇的最稳定结构为线型结构，(CaN6)n(n=2～5)团簇首先由两个叠氮基与两个Ca原子构成一个近似菱形，再由菱形相互垂直形成链状最稳定结构；叠氮基中间的N原子显示正电性，两端的N原子显示负电性，且与Ca直接作用的N原子负电性更强，金属Ca原子和N原子之间形成很强的离子键；(CaN6)n(n=1～5)团簇最稳定结构的IR光谱分为4个部分，其最强振动峰均位于2195～2280cm-1，振动模式为叠氮基中N-N键的反对称伸缩振动；稳定性分析显示，(CaN6)3和(CaN6)5团簇相对于其他团簇较为稳定。

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。
