摘要
叙述了不同热力学过程中熵变的计算方法,并将克劳修斯不等式应用于各种热力学过程,定性和定量讨论了熵判据的具体应用,解决了利用熵变判断过程的可逆性和自发性问题。
In this paper, the method to calculate the enthropy change was illustrated, and the application of Clausius unequal relation was discussed. Moreover, the application of enthropy criterion to judge the possibility of the thermodynamic process occurring was studied qualitatively and quantitatively, and the problem of to judge the occurrence possibility of the reversible process or irreversible process by enthropy criterion was resolved completely.
