The experimental results are as follows:(1) Without EAF the fouling resistance increase along with addition of time and change of the heat transfer coefficient is just contrary to the result. However, with EAF fouling resistance still enhances at the beginning of experiment and later, it gradually minishes after experiment has started for some time. Of course, the change of heat transfer coefficient still is contrary to the outcome. But when experiment lasts longer time, fouling resistance and heat transfer coefficient change in the same trend as the fore results at the beginning of the experiment. However, They all go to the tranquilization until the last.

实验结果表明：(1)没有经过电磁处理时，污垢热阻随着时间的增加而增加，换热系数随着时间的增加而减小；一旦经过电磁场的处理，污垢热阻开始时仍呈上升趋势，经过一段时间以后，便逐渐下降，换热系数的变化与此正好相反，即在实验开始时呈下降趋势，后来逐渐上升；当实验时间延长时，发现污垢热阻及换热系数在实验开始时的变化趋势与前面的实验结果基本相同，但到后来，二者的数值则分别均趋于稳定。
