| 摘 要： | Grover根据实验数据给出，液态金属的定容比热随温度近似线性减小：cV≈3R-ζRT/Tm，式中T为温度，Tm为熔化温度，R为普适气体常数，ζ为经验常数，其值在0.11至0.24之间，就平均来说，ζ≈0.15。利用Lennard-Jones-Devonshire理论对这一经验关系进行了解释。

| Abstract: | Based on the experimental results, Grover1] presented an approximation formula for the specific heat at constant volume of liquid metals versus temperature: cV≈3R-ζRT/Tm, where T is the temperature, Tm is the melting temperature, R is the gas constant, ζ is an empirical constant, with value of 0.11~0.24, its average value is about 0.15. In this paper, the approximation relation is deduced by using the Lennard-Jones-Devonshire theory. |
