A chemical bond consisting of a hydrogen atom between two electronegative atoms (e.g., oxygen or nitrogen) with one side be a covalent bond and the other being an ionic bond .

一种化学键：由两个负电原子及其间的氢原子组成，其中一边是共价键，另一边是离子键。

If the optical electronegativity Dwglass is high, the materials are considered ionic in nature and if its magnitude is less, the materials are considered to be covalent in nature.

如果光 电DW的玻璃是高，材料被认为是离子的性质，如果其规模较小，材料被认为是共价键的性质。

The components and molecular aggregation in mixed Langmuir films and LB films are strongly affected by some non-covalent intermolecular interactions, such as electrostatic interaction, hydrogen bond, complexation, van der Waals force, etc.

在混合Langmuir膜和LB膜中，分子的组分和集合形态在很大程度上受到分子间作用力的影响，这种分子间作用力都是是非共价力，如静电相互作用、氢键、配位、范德华力等作用。

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。
