有效能(烔)作物质富集程度量度的热力学分析

Thermodynamic Analysis for Measure of Natural Concentration of Material in Available Exergy

本文从物质要素分散扩散和富集的热力学分析出发，探讨了物质体系物质富集状态（或污染状态）的能量状况，从而讨论了浓差有效能作为物质富集程度（或污染程度）的能量指标的依据及其有效性，指出了其研究和应用的理论意义和实际意义。

In this paper is given an analySis for dispersion and concentration process of various elements of meterials from the view of thermodynamic principles to try to establish an exergy formula for the material when being concentrated or polluted. The energy formula, in author's opinion, is theoretically and practically very useful in definition of exergy index as an indicator of concentration or pollution in a material system.
