摘要： 基于对 Kon hi四日校正曲线的研究。推导了校正系数 C 与参数 a、b 之间怡终满足 C=a/b 的规律关系。采用了一种倒敦形式的 KoПbITOB 校正曲线变形公式。该式可以直接通过回归 求得校正系数 C 与参数 a、b。分析论证了瞬时产量与阶段（年或月）产量之间的关系。并推导给出了年（或月）产量的预测公式。指出传统用瞬时公式 Q = dNp/dt 预测年〈或月）产量的不合理性。

Abstract: Based on the studies of Kopitov corrected curve, the regular relational ex-pression is ded uced that there is C=b/a between correction coefficient C and parameters a,b. A modified formula of reciprocal Kopitoy corrected curve has been adopted, and C=a/b can be got by regression from it. This paper ana lyzed and proved the relation of momen-tary output and stage (year or month) output. It is pointed out that it is unreasonable to use the formula Q = dNp/dt to predict stage output.
