根据传热学原理和美国传热协会（ HEI）提供的凝汽器换热系数公式进行数学推导，并根据泰勒公式进行合理简化，得到汽轮机冷端各参数的变化对排汽温度影响的函数关系式，分析了函数关系式的误差并指出了应用条件。得到的函数可以用于对冷端调整和改造必要性的分析，对汽轮机冷端节能具有指导意义。

Based on heat transfer theory and formula for heat transfer coefficient of condenser provided by American heat exchange institute(HEI) and mathematical derivation,and reasonably simplify according to the Taylor’ s formula,get the function of changes of steam turbine cold end parameters on exhaust steam temperature, the paper analyzed the function relationship of the error and points out the application conditions.The function obtained can be used for the analysis of the necessity of cold end adjustment and transformation, and has the guiding significance for the energy saving of the cold end of the turbine.
