摘　　要：在物理化学教材中,对于等温过程的定义存在较大的争议,因此有必要对等温过程的准确定义进行辨析。分析物理化学教材中不同情况的等温过程后得出,等温过程是指环境温度恒定不变,系统的始态和终态温度相同并等于环境温度的过程,而且变化过程中系统温度可以有波动,温度波动的大小对于系统过程要视具体问题而言。It is necessary to analyze dialectically the accurate definition of isothermal process, because the definitions of isothermal process in Physical Chemistry teaching materials are different. Various isothermal processes in Physical Chemistry teaching materials are analyzed, and the definition of isothermal process is concluded. The isothermal process is the process that the initial temperature, final temperature, and the environmental temperature are equal, and the environmental temperature is constant. Furthermore, the system temperature may fluctuate during the process, and the magnitude of temperature fluctuation is different for various processes.

关 键 词：等温过程 等温变化 恒温过程
