摘要
以氩晶体为例,讨论了非简谐振动对面心立方晶体的热膨胀系数、压缩系数、热容量以及状态方程等的影响,求得了格林爱森常数随温度变化的关系式,分析了定压热容量随压强变化的规律,所得结果与实验事实基本相符.
Taking Argon (Ar) crystal as an example, this paper investigated the effects of non-simple harmonic vibrations on the expansion coefficient, compression coefficient, heat capacity and equation of state of the face-centred cubic crystal, and thus found out the relation between Gelinnaisen coefficient and temperature which is of covariation kind. This paper also provided an analysis of the law of heat capacity under constant pressure varying along with the changes of pressure. The analytical results agreed fundamentally with the experimental results.
