Under irradiation of UV light, PR-DR changes its crosslinking structure from ionic bond to covalent bond and becomes insoluble in DMF. This character can be used in practice as a photo-imaging material.

在紫外光照下，PR-DR的离子键将转化为共价键从而不溶于DMF，因而可用作光成像材料。

There is a less difference of ionic bond in Ti_2AlC and Ti_2AlN, the covalent bond of Ti_2AlN is larger than that of Ti_2AlC. Analysis of the total density of states, the trend forming forbidden band of Ti_2AlC was more evident than that of Ti_2AlN, which made the conductivity of Ti_2AlN than Ti_2AlC.

从总态密度可见，Ti_2AlC和Ti_2AlN都有在最低导带和最高价带之间形成较窄的禁带的趋势，即表现出形成混合型导体的趋势，而Ti_2AlC形成禁带的趋势要比Ti_2AlN更为明显，这与Ti_2AlN的电导率大于Ti_2AlC的实验结果一致。

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。

The results showed that zinc ion in the polymer formed ionic bond and coordinative bond with carboxylic group. The studies on the film property of PZA indicated that the film highly tolerate water but its adherence was a little weak

并首次深入研究了该种聚合物的吸湿保水性，发现其吸湿性随环境湿度变化而变化，对环境具有很好的响应性；在加热蒸发过程中，具有比自由态的水慢的蒸发速率。
