| Abstract: | 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. |
