摘 要: | 本文指出,运用公式计算外界对热力学系统所做的体积功时,应当注意“系统整体没有运动”这一条件,同时还应注意式中dV只应是系统体积的改变,不宜作其它理解,否则将会导致混乱或谬误.

关 键 词: | 热力学,系统,体积功 |

Abstract: | It is pointed out that when the volume work done by the outside world to the system is calculated with,the whole system should be at rest and dV should be the change in volume of the system, and not any others. |
