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 show that the calculated cell parameters are in agreement with the experimental ones. The interactions between Li—N and Al—N are strong ionic bonds in Li3AlN2. The interaction between N and H is strong covalent bond and the interaction between Li and N is strong ionic bond in LiNH2. The calculated reaction enthalpies are 23.7 and 55.3 kJ/mol, respectively, which are in agreement with the experimental ones.

结果表明：Li3AlN2的Li—N、Al—N键主要为离子键，LiNH2的N—H键主要为共价键，Li—N键主要为离子键；298 K时贮氢反应的反应焓计算值分别为23.7和55.3 kJ/mol，与实验值均符合得较好；反应中各固态、气态物质的晶胞的结构优化后的晶格常数、键长与键角等与相应的实验值均符合较好。
