| 摘 要： | 本文应用近年来海河下游监测数据对ＤＯ与ＮＨ３Ｎ和ＣＯＤＭｎ进行一元线性回归，得到两回归方程：ＮＨ３Ｎ＝－１２８ＤＯ＋１０５４；ＣＯＤＭｎ＝－１１３ＤＯ＋１６９２。并经相关系数和回归系数显著性检验，表明在９９９％的置信水平下ＤＯ与ＮＨ３Ｎ和ＣＯＤＭｎ线性相关均极其显著

| Abstract: | This paper does simple linear regressions between DO and NH 3 N as well as COD Mn by using Hai River's tailed monitoring data in recent gears, and so gets two regression equations:NH 3 N=-1 28 DO+10 54;COD Mn =-1 13 DO+16 92.Then it demonstrates that the linear correlations between DO and NH 3 N as well as COD Mn are both extraordinarily significant at a significance level of 99 9% by means of significance tests on correlation coefficients and regression coefficients. |
