研究松花江水在换热过程中，主要水质参数对表面污垢热阻的影响程度，分别测定3种管型在换热过程中水质参数的变化情况，所选管型分别是光管、交叉缩放椭圆管和不连续双斜向内肋管，水质参数为pH、碱度、电导率、溶解氧、钙离子浓度和亚铁离子浓度。应用灰色关联方法，将水质数据和污垢热阻数据进行关联分析得出，两种强化管的水质参数关联顺序相同。其中的两种参数与污垢热阻呈现同向变化趋势，其余参数与污垢热阻呈现反向变化的趋势。强化换热管不但对水质参数的变化产生影响，而且对关联程度也有影响。

The influence of the Songhua River water quality on the fouling resistance in heat transfer process was studied. The water quality variation in the heat transfer was measured in three types of heat exchange tube, including a general circular tube and two enhanced tubes, alternating elliptical axis tube and discrete double inclined ribs tube. The measured water quality parameters are pH, alkalinity, conductivity, DO, Ca2+ and Fe2+ concentrations. The fouling resistance is correlated with the water quality parameters with the gray correlation method. The results show that the parameter correlation order is the same for the two enhanced tubes. The variation tendency of fouling resistance is the same as two of the water quality parameters and opposite of the other parameters. Compared with circular heat exchange tube, the enhanced heat exchange tube affects not only the water quality parameters, but also the parameter correlation.
