摘　　要：从热力循环角度考虑,提升工质初参数与降低工质终参数是提升发电厂循环热效率的一种主要方法。若要降低工质终参数则需要在汽轮机排汽口建立高度的真空。从理论与实际两方面探讨了如何提高汽轮机凝汽器真空以及确定其最佳真空。From the view of thermodynamic cycle, increasing medium initial parameter and decreasing working medium end parameter are a main method to enhance circulating thermal efficiency of power plant. Vacuum degree should be established at the steam turbine exhaust port if it needs to reduce the working medium end parameter. How to enhance vac- uum degree and determine optimum vacuum degree of condenser steam turbine are discussed from theory and practice.
