摘　　要：通过对近两年尔王庄水库化学需氧量(CODCr)和高锰酸盐指数(CODMn)的监测,对二者的相关性进行了一元线性回归分析,得出二者的回归方程为y=3.823,x-2.067,1,相关系数R=0.908,7,对二者相关性进行了显著性检验,检验所得F值远大于F0.01(1,27)。因此二者具有十分显著的相关性。故化学需氧量(CODCr)可由高锰酸盐指数(CODMn)通过一元线性回归方程计算得出。Based on the past two years’ monitoring of chemical oxygen demand(CODCr)and permanganate index(CODMn) in Erwangzhuang reservoir,a linear regression analysis was carried out to reveal the correlation.The regression equation and coefficient were obtained respectively:y=3.823,x-2.067,1,R=0.908,7.As correlation significant test indicated,the F value is much greater than F0.01(1,27),which proves that the two factors have a very significant correlation.Therefore,the chemical oxygen demand(CODCr)can be calculated by permanganate index(CODMn)by a linear regression equation.

关 键 词：化学需氧量(CODCr) 高锰酸盐指数(CODMn) 相关性
