摘　　要：对凝汽器最佳真空的传统定义没有考虑冷却水的费用及环境方面的因素,存在片面性。本文考虑了这些因素,修正凝汽器最佳真空的定义。根据该定义,对运行中的机组最佳真空进行重新计算,确保机组能在更加经济的真空下运行。The payment for the cooling water and the pollution were not taken into account in the traditional definition before,so it is unilateral. In view of these,the optimal condenser vacuum is rectified and calculated again based on the new definition. According to the rectification, calculation and programming, numerical value of condenser vacuum is more veracious.
