摘　　要：原有的热经济学分析方法按照产品等价原则和蒸汽等价原则分摊成本,没有体现按能质高低分摊成本的经济原则,影响产品的真实性。本文引入了能质系数的概念,把能量的品质与其成本有机地结合起来,推导出了新的补充方程,使得热经济学分析结果更具有科学性和合理性。The thermal economics analysis allocates cost according to product equivalent and steam equivalent principle. As a result, it can＇t reflect the economic principle that allocates cost as per energy quality and affects product authenticity. The essay introduces the concept of energy quality coefficient, deduces the new supplementary equation by combining energy level of product with unit exergy cost. So it is demonstrated that the result of thermal economics analysis is much more scientific and reasonable.
