We experimentally analyze the heat capacity and thermal expansion of reference solids in a wide temperature range from several Kelvin to melting temperature, and establish a universal double-linear relation between the experimental heat capacity C _p and thermal expansion β, which is different from the previous models. The universal behavior between heat capacity and thermal expansion is important to predict the thermodynamic parameters at constant pressure, and is helpful for understanding the nature of thermal properties in solids.

固体热容量和热膨胀之间的标度行为

我们通过实验分析了参考固体在从几开尔文到熔化温度的宽温度范围内的热容量和热膨胀，并建立了实验热容量C _p和热膨胀β之间的普遍双线性关系，这有别于前人楷模。热容量和热膨胀之间的普遍行为对于预测恒定压力下的热力学参数很重要，并且有助于理解固体热性质的性质。
