中文摘要：

从广义力与流的角度，探讨了传递现象的共同本质，即各种强度量势场梯度作用下的能流和[火用]流。运用非平衡态热力学的相关理论，推导了多势场影响下的[火用]传递唯象方程。根据非平衡态热力学分析不可逆过程的一般步骤，提出确定[火用]传递唯象方程力与流的两种方法，体现了热力学和传输学在[火用]传递研究中的学科交叉。对热电耦合现象的应用分析表明，基于非平衡态热力学的[火用]传递唯象方程，能够完整、深入地揭示不可逆效应之间的耦合关系。

英文摘要：

From the point of generalized force and flow, the common essence of transfer phenomenon is discussed, i. e. energy flow and exergy flow effected by all kinds of intensity potential field grads. The related theory of non- equilibrium thermodynamics is used to deduce the exergy transfer phenomenological equation influenced by multi- potential fields. According to the general step of analyzing irreversible process in non - equilibrium thermodynamics, two ways of determining force and flow in exergy transfer phenomenon equation are provided, which embodies the subject intersection of thermodynamics and transfer knowledge in exergy transfer study. The application analysis of thermo- electric coupling phenomenon shows that, the phenomenological equation of exergy transfer based on non - equilibrium thermodynamics can open out fully and thoroughly the coupling relations between irreversible effects.
