| 摘 要： | 讨论了理想气体和范德瓦耳斯气体的绝热过程，着重指出理想气体的摩尔热容比只在高温段可看作常量．而范德瓦耳斯气体的摩尔热容比即使在高温段也不可看作常量． |
| 关 键 词： | 理想气体 范氏气体 热容 绝热过程 摩尔 常量 再认识 |

| Abstract: | The adiabatic processes of ideal gas and van der Waals gas are discussed.It is emphasized that the ratio of molar heat capacity at constant pressure to the one at constant volume for ideal gas can be regarded as a constant only at high temperature,and cannot be regarded as a constant for van der Waals gas even at high temperature. |
| Keywords: | ideal gas van der Waals gas quasi-static process adiabatic process molar heat capacity |
