摘　　要：运用数理统计的双因素方差分析法分析水处理实验数据,比仅用单因素方差分析法可获得更多更全面的规律信息,有助于水处理实验的深入研究。通过运用双因素无重复实验的方差分析法对某组混凝沉淀实验数据进行实例分析,结果表明此分析方法可得出两种因素对实验结果的影响显著性,还可以得出两种因素的交互作用对实验结果的影响显著性,并可根据显著性大小分析出因素的主次顺序。Using the two-factor variance analysis method to analyze the data of water treatment experiment is better than only using the single factor variance analysis method. It can obtain more comprehensive information to contribute to the further research of water treatment experiment. By using the two-factor variance analysis for no-repeated experiment to process the data of a certain set of coagulation and sedimentation experiments, it shows that this analysis method can conclude the significance of the two factors on the result of the experiment. By using two-factor variance analysis method for repeated experiment to process the data of a certain set of filtration experiment, it shows that this method can conclude not only the significance of the two factors on the result, but also the significance of the interaction of the two factors and the order of importance of these factors according to the significance.
