理想气体多方过程只是任意过程的一个特例

摘要

一些教材中认为理想气体多方过程可以代替成任意过程。通过对理想气体任意过程的分析，认为这些教材的见解是不太合适的，理想气体多方过程只是任意过程的一个特例。%There are the assumption in some textbooks that ideal gas polytropic process can be replaced by arbitrary process.According to the analysis of ideal gas polytropic process,thought that the ideas in those textbooks is inappropriate,and the ideal gas polytropic process only is one exception of arbitrary process.
