摘要
提出了传递公理,即任何形式的传递过程都是在相应基本强度量差推动下,基本广延量的流动过程;基本广延量的传递过程也同时是与之对应的能和(火用)的传递过程。定义了热力学流密度和热力学力的数学表达式,在传递公理的基础上,利用能和(火用)的普遍化表达式,分别建立了三类广延量的传递定律。利用传递定律,结合广延量的平衡方程,导出了传递方程的普遍化表达式。
A transfer axiom is proposed, which declares that any form of transfer process is driven by the difference of the corresponding basic intensive property, and the transfer of basic extensive property in the process must be accompanied with the corresponding energy and exergy. The mathematic expressions of thermodynamic flow density and thermodynamic force are denned. Based on the transfer axiom, three kinds of transfer law are established. With the transfer laws and the balance equation, three kinds of generalized expressions of transfer equations are derived.
