And on the basis 近年来，能源短缺已成为我国乃至全世界经济 of the unified physical model, the basic mathematic model was 可持续发展的最大制约因素，节能降耗成为世界各 also established, which was actually specific internal work 国所面临的重大问题。作为能耗大户的火电厂，进 equation, cycle heat absorption capacity equation and 行节能降耗更是刻不容缓。要做好火电机组节能降 steam-water distribution equation. The unified physical model 耗工作，必须对其热经济性进行在线和离线的多角 is of standard and concise form, and the mathematic model is of simple and unified physical structure, whose
