The next bond is a double bond this happens when two pairs of electrons share.

第二种为双键，有两对共用电子对时则形成双键。

This indicates that the peptide bond has some characteristics of a double bond, because of resonance stabilization with the carbony1 oxygen.

肽 当一个氨基酸分子的氨基与另一个氨基酸分子的羧基起反应时，便形成一个肽键，同时释放出一分子水。

The peptide bond has partial double bond character and is nearly always in the trans configuration.

半胱氨酸残基之间共价二硫键的位置也包括在一级结构之中。

Except for the high frequencyvibrations related to the changes of bond lengths and bond angles,the low frequencyvibrations related to the changes of double plane angles contribute to the internalreorganization energy significantly.

除与键长，键角变化相应的高频振动的贡献外，与二面角变化相应的低频振动对内重组能也有显著贡献，这也是导致〓，〓，及〓体系内重组能及自交换速率常数不同的主要原因。

Reagents and so on temperature, organic solvent, potential of hydrogen, urea, amide may cause the DNA member to denaturate, even if hydrogen bond break between the DNA duplet bond's, the double helix structure unties.

温度、有机溶剂、酸碱度、尿素、酰胺等试剂都可以引起DNA分子变性，即使得DNA双键间的氢键断裂，双螺旋结构解开。

A large number of bond-type complexes, as long as the hydrogen of the molecules covalently coupled to the molecular approach in an electronegative atom up, that constitutes a hydrogen bond, there are intramolecular hydrogen bonds and intermolecular hydrogen bonds of the points, will affect the formation of complex reaction carried out, such as in solution adding dioxa cyclohexane, or tetrahydrofuran, will reduce the alkylation reaction rate.

氢键型络合物为数众多，只要含氢的分子以共价键方式耦合到分子中一个电负性原子上去，即构成氢键，有分子内氢键和分子间氢键之分，络合物的形成将会影响反应的进行，如在溶液中加入二氧杂环己烷或四氢呋喃，都会降低烷基化反应速率。

Based on the models, we elucidated the distribution of the stericfield, the hydrophobic field, the electrostatic field, the hydrogen bond acceptor andhydrogen bond donor, which contribute to the activity.

通过对CoMFA和CoMSIA模型的分析，确定了抑制剂上对活性有利的立体大基团、疏水性结构、电性基团以及氢键供受体等在靶酶活性结合部位的空间分布情况。

As a result, electrostatic interactions and hydrogen bond were identified to contribute to the affinity interaction, while hydrophobic interaction contributed little. Moreover, the importance of electrostatic interactions and hydrogen bond to the affinity changed with pH value.The effect of rate of mobile phase on the retention of insulin was researched and the dynamic adsorption isotherm was got by analyzing the breakthrough data with Langmuir equation.

通过调节流动相的pH值和离子强度，并使用尿素和乙二醇分别对吸附蛋白进行洗脱，详细研究了吸附效果最好的目标蛋白质与肽配基之间的亲和吸附机理，发现静电作用和氢键是二者之间产生亲和吸附的主要作用力，而疏水相互作用对该亲和几乎没有贡献。

The interaction of DAB and RB with SPM and the cells are exothermal and idiopathic, which contained the union of non-covalent bonds, such as electrostatic bond, hydrogen bond and van der Waals force. Moreover, most of DAB and RB were accumulated on the excellular membrane and walls, to hardly enter the cytoplasm.

结果表明， DAB， RB与SPM和细胞外膜有强烈的单分子层化学吸附，是自发的放热反应，主要通过电荷对吸引、氢键等非共价键结合在SPM和细胞外表面，且绝大部分DAB， RB积累、滞留在细胞膜壁上。
