摘　　要：首次提出等效降法的概念,并利用这一概念结合矩阵建立了热力系统主系统状态方程。该方法为热力系统的分析提供了一种全新的思路,可直接计算热力系统热功转换效率,具有与常规分析方法相比概念清晰,易于理解,适合计算机程序化等特点,为实际系统定量分析奠定了一定的基础。以某N300-16.7/537/537-6再热机组为例,验证了状态方程与常规平衡法计算结果是一致的。The concept of equivalent exergy drop was firstly presented. Combining with matrix equation, the paper constructed main system exergy equation of state in thermal system. This kind of method offers a completely new mentality for exergy analysis of thermal system. It can directly calculate the heat transition of work exergy efficiency. Contrasting with conventional exergy analysis methods this kind of equation has some characteristics which are clear to command, suitable for computerization calculation. The identity between exergy equation of state and exergy equilibrium method was proved correctly by case study on an N300-16.7/537/537-6 reheat unit.
