摘　　要：应用2009年松花江佳木斯江段丰、平两水期监测数据对CODCr与CODMn进行一元线性回归,得到回归方程,并经相关系数显著性检验,表明在95%的置信水平下CODCr与CODMn线性相关极其显著.Application of the Songhua River section of Jiamusi in 2009,the water of two periods to the CODCr and CODMn by the linear equation calculates,the Regression equation was obtained,according to the related the numbers from the experiments,which indicated that the relationship between CODCr and CODMn of the lenear is very significant under the 95% confidence level.

关 键 词：显著性检验 相关关系 回归方程
