孪连表面活性剂是一种结构较为特殊的新型表面活性剂，其分子中至少含有两个亲水基和两条疏水链，在其亲水基或靠近亲水基处，由联接基团通过化学键联接在一起。

It is found that from bond population calculation results, the bonding strength of Al—O bond of faces (011) and (011) of gibbsite are stronger than that of face (001). If the proportion of unfold of (001) surface is decreased and the proportion of unfold of (011) and (011) surfaces is increased to same possible extend, the bonding strength of Al—O bond of gibbsite would be more strong.

键布居分析结果表明，整体上氢氧化铝的(001)面的Al—O键的结合力不强，(011)和(110)面的Al—O键的平均键布居数较高，结合力较强；若小幅度降低(001)面的显露比例，并使(110)和(011)面较多显露，就有可能提高氢氧化铝表面的Al—O键的结合力。

Particularly in theβsubunit, the rotation of the distal HisE7 (63) imidazole ring about the Cα-Cγ bond and its large distance from the haem plane make a hydrogen bond possible between E7 Nε and the terminal binding oxygen atom, while in human oxyHb this hydrogen bond either does not exist or is only very weak.

这个氢键在人oxyHb分子中要么不存在要么很弱。

Accordingly, in order to provide insight into the function of coenzyme B12 and the mechanism of enzymatic catalysis, it is necessary to investigate the conformational change of corrin ring accompa-nying the Co-C bond homolysis, the Co-C bond dissociation energy, and the factors influencing the Co-C bond strength.

激光诱导时间分辨光声量热法(laser-induced optoacoustic calorimetry，简称LIOAC；或time-resolved photoacoustic calorimetry，简称PAC)是在纳秒至微秒时间量级上直接定量检测激光诱导光化学反应及光生化反应过程中能量传递以及有关反应分子体积变化的新方法。

The result indicates that the hyperconjugation effect from lone pairs on nitrogen atoms to germinal N-N bonds can play an important role in the N-N bond length. The N-N bond length displays reverse dependence on the charge density in bond critical points obtained from AIM.

NBO分析表明N原子孤对电子到相邻的氮氮键的超共轭作用是影响氮氮键长变化的主要因素，AIM计算的氮氮键的键临界点电荷密度与键长呈反比关系。
