论文摘要
在最近的一篇论文（物理学修订版E {\ bf 104}，014103（2021））M。Baggioli和A. Zaccone中，通过使用Debye的表达来对液体的特定热量进行理论描述，以表达固体的特定热量并插入态度（DOS）（DOS）的特定热量（DOS），以表达液体液体模式（代表AINSTANES-NOSTANES-NOMENS MODENANES MOMED）（代表ANMSTANES-NOMSATEN MODENSMODE）（INMSTANES-NOSTANTANES MOMED）（INM）。但是，Debye的量子力学程序不能用于经典液体，而INM光谱的作者公式并不代表已知的简单液体的INM光谱。此外，该公式从其模型运动方程式从数学上是错误的。最后，通过拟合{\ it超临界流体}的数据来执行{\ it液体}的特定热量的TeORY测试。 \ new {对我们而言，}这些以及许多其他不一致使这项工作不适合研究液体的特定热量。
In a recent paper (Phys. Rev. E {\bf 104}, 014103 (2021) ) M. Baggioli and A. Zaccone formulate a theoretical description of the specific heat of liquids by using Debye's expression for the specific heat of solids and inserting a density of states (DOS) which they claim to represent the instantaneous-normal-mode (INM) spectrum of a liquid. However, the quantum-mechanical procedure of Debye cannot be used for a classical liquid and the authors' formula for the INM spectrum does not represent the known INM spectra of simple liquids. Furthermore, the derivation of this formula from their model equation of motion is mathematically in error. Finally experimental test of the teory for the specific heat of {\it liquids} is performed by fitting the data of {\it supercritical fluids}. \new{To our opinion,} these and a lot of other inconsistencies render this work not suitable for studying the specific heat of liquids.
