摘要

最近，针对固体和液体材料在宽温度范围内的热容量建立了一个新模型，并表明热容量还取决于热膨胀或体积。在本研究中，我们进一步分析了模型中参数的物理意义，完善了热容量模型。完善后的模型计算出的热容与实验结果十分吻合。该模型预测了材料中普遍存在的体积-能量关系，具有重要的理论价值。

General behavior of heat capacity and volume-energy relation in materials

A new model of heat capacity is established for solid and liquid materials in the wide temperature range recently, and shows that heat capacity is also dependent on thermal expansion or volume. In this study, we further analyzed the physical meaning of the parameters in the model, and perfected the heat capacity model. The calculated heat capacity in the perfected model is well in accord with the experimental results. And a universal volume-energy relation in materials is predicted by the model, and has important theoretical value.

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
