摘　　要：本文采用回归求解法，求出了该厂捷产Ｋ１１０－１３０ 型汽轮机配套凝汽器的使用时间与凝汽器端差存在的线性关系。然后再经计算年累计经济报失，与凝汽器更换铜管的大修费用相比较，当两者相接近时，便作为该凝汽器的合理大修时间。Czechoslovakia made K110-130 turbine has been used in NO. 2 Power Station of Anshan Iron and Steel Company. This contribution derived linear relationship be- tween applying time and end difference of condenser of K110-130 turbine with regression derivation method. It calcul ated accumulative loss expenses in a year and compared this with overhaul expenses for replacement of copper tubes in condenser. When the accumula- tive loss expenses come hearto overhaul expenses, it is the reasonable overhaul time of the condenser.
