| 摘 要： | 本文在正确理解功与能,过程量与状态参数等基本概念的基础上,论证了在工程热力学中,pv的物理意义应理解为推动功(或称流动功),而不能理解为工质自身所具有的某种能,如压力势能或流动能等。

| Abstract: | In engineering thermodynamics, different understandings of pv involve
the recognitions of basic conceptions on physical meaning of enthalpy, on quan-
tity of process and parameter of state, on work and energy. For this reason, it
is necessary to discuss the property of pv. Based on the correct understanding of the
concepts of work and energy, quantity of process and parameter of state, it is
proved in this paper that the physical meaning of pv in engineering thermodyna-
mics should be understood as the push work (or flow work) but not certain ener-
gy of flow in itself, such as pressure-potential energy, etc. |
