摘要: 利用《物理化学手册》中在标准状态下空气、氢气、氮气、氧气和二氧化碳的实验数据,结合误差分析,局部验证了 pVT 系统热力学公式Cp - CV = pTVαβ 的正确性,同时印证了相关热力学理论及数学推理过程的可靠性.

Abstract: By using the experimental data of air,hydrogen,nitrogen,oxygen and carbon dioxide in the

standard state in Handbook of Physical Chemistry and combining with error analysis,we verify partially the
correctness of the thermodynamic formula of Cp - CV = pTVαβ in pVT system. Accordingly,the reliability of the related
thermodynamics theory and mathematical reasoning process are confirmed.
