| 摘 要： | 边界热质传递过程的主动传递(Active Transport)为由"低势"向"高势"的物量(包括质量、能量和信息等)传递,传递动力由边界内的其他能量(如化学反应等)或耦合作用提供,主动传递过程已经超越经典传热学和热力学的范围.基于Kedem分析方法,采用传热学和不可逆热力学理论相结合的方法研究边界热质传递过程的主动传递机理,提出耦合流、正耦合、负耦合和耦合程度等概念,并以两组分膜分离系统为例进行分析.

| Abstract: | The active transport in the process of boundary heat and mass transport is the transference from "low potential energy" to "high potential energy"(including mass,energy,momentum and information,etc.).The dynamic force of transport is provided by other energies within the boundary(e.g.chemical reaction etc.) or coupling action.The active transport process is beyond the range of classical heat transport theory and thermodynamics.Based on Kedem Approach,this paper adopts the combined method of Heat Transport Theory and Irreversible Thermodynamics to study the active transport mechanism in the process of boundary heat and mass transport and put forward the concepts such as coupling flow,ortho coupling,negative coupling and coupling degree and make analysis through the examples of two groups of membrane detachment systems. |
