摘　　要：在假定火无和火用的使用价值之比的系数ｋ等于能级Ω的基础上，导出了通用的折合火用计算公式，由此揭示了折合火用随能级的变化规律，进而证明了折合火用为一状态函数。折合火用分析能够更加全面准确地评价不同质能量的使用情况，而且以折合火用量法确定热、电冷产品的价格更为科学合理。.On the basis of the assumption that factor K of the ratio of use value of non usable energy and exergy is equal to energy level Ω,deducted is a universally applicable formula for calculating reduced exergy.From this one can perceive the variation relationship of reduced exergy with energy level,thereby proving that the reduced exergy is a status function.The analysis of the reduced exergy can lead to a more comprehensive and accurate evaluation of the use conditions of various energy quantities.Moreover,the determination of the price of heat,electricity and cold products by the reduced exergy method is more scientific and rational.
