　　基于水处理技术抑垢及缓蚀效果在线监测实验台，分析了电磁场作用下换热器结垢过程中各典型水质参数的变化，并用均衡接近度灰关联分析方法表述了电磁场作用下特定循环水典型水质参数与换热器污垢热阻之间的关系。结果表明：在电磁场作用下换热器结垢过程中，电导率、溶解氧及浊度较未加磁对比实验的高，而pH值较未加磁对比实验的变化甚微。通过分析水质参数的变化发现：电磁场作用下，水质参数与污垢的形成过程密切相关。其中，电导率对换热器的污垢热阻影响显著，而pH值的影响最小。为建立多水质参数与污垢热阻之间数学模型选取合适的参数及探索电磁抑垢机理，制定有效的防垢、抑垢对策提供了实验依据和理论参考。

Based on the fouling prevention and anti-corrosion effect of online evaluation experiment in water treatment,the influence of the electromagnetic field on fouling resistance and typical water quality parameters was investigated. The relationship between typical water quality parameters and fouling resistance was quantitatively expressed using the correlative degree analysis and balanced adjacent degree. The results showed that in the forming process of fouling on the surface of heat exchangers in electromagnetic field,conductivity,dissolved oxygen,and turbidity were higher than contrast experiments and the pH value was lower. The analysis of the variation of water quality parameters showed that the water quality parameters correlated to the fouling in electromagnetic field. Conductivity had greatest impact on the fouling resistance of the heat exchangers,and pH had the least influence. Conductivity , turbidity , dissolved oxygen were more suitable for constructing the mathematical model of water quality parameters and fouling resistance. This method provided the experimental and theoretical basis for the suitable selection of mathematical model of water quality parameters and fouling resistance,mechanism of electromagnetic anti-fouling technology and effective measures for fouling prevention.
