| 摘 要： | 基于对ｋ校正曲线的研究，推导了校正系数Ｃ与参数ａ、ｂ之间始终满足Ｃ＝ａ／ｂ的规律关系。采用了一种倒数形式的Ｋ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＝ｄＮ＿ｐ／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 deduced that there is C=b/a between correction coefficient C and parameters a,b.Amodified formula of reciprocal Kopitov corrected curve has been adopted, and C,a,bcan be got by regression from it.This paper analyzed and proved the relation of momen-tary output and stage(year or month)output.It is pointed out that it is unreasonable touse the formula Q=dN_p/dt to predict stage output. |
