摘　　要：本文应用能斯特公式阐明当温度等于绝对零度时,热力学系统进行的所有过程都是可逆等温的,与可逆绝热过程重合,不存在零点热,解决了教科书和文献中提出但没有回答的问题。对于不满足能斯特方程的热力学系统,是否存在零点热有待于进一步研究。In this paper,the Nernst equation is applied to illustrate that when the temperature is equal to absolute zero,all the processes of a thermodynamic system are reversible and isothermal,overlapping with reversible adiabatic processes,and there is no zero-point heat.This solves the problem raised in textbooks and literature but not answered.For the thermodynamic system that does not satisfy the Nernst equation,further research is needed to determine whether there is zero-point heat.

关 键 词：能斯特公式 绝对零度 可逆等温 可逆绝热 零点热
