摘要：

The　experimental　study　on　the　effect　of　parameter　variations　including　cooling　water　velocity,　particle　concentration　and　particle　species　during　the　forming　of　the　mixed　scale(MgO　and　CaCO3)　and　the　other　one(SiO2　and　CaCO3)　has　been　carried　out　by　dynamically　monitoring　of　fouling　thermal　resistance.　Meanwhile,　the　scale　inhibition　performance　of　low　voltage　electronic　apparatus　is　investigated　when　it　is　used　to　treat　the　two　kinds　of　mixed　scales　under　different　electric　currents(0.2　A,　1.0　A).　The　comparsion　between　fouling　thermal　resistance　and　heat　transfer　coefficient　indicate　that　low　voltage　electronic　apparatus　has　apparent　anti-fouling　effect　for　the　mixed　scale(MgO　and　CaCO3),　but　different　for　the　mixed　scale(SiO2　and　CaCO3).
