摘　　要：利用双道的实时监测系统,通过监测碳酸钙过饱和溶液中的pH和Ca2+浓度在析晶过程中的变化,系统的研究了不同流速下磁场的阻垢效果。准确、可重复的试验数据表明,磁场对碳酸钙过饱和溶液有阻垢效果,并且不同流速下磁场的阻垢效果不同。同时试验结果还表明在磁处理时间恒定的条件下,在0～6 m/s的流速范围内,溶液通过磁场的流速越高磁处理的阻垢效果越强。The effect of magnetic field on the CaCO3 precipitation with different treated flow rates has been studied with the system which could measure the pH and the concentration of Ca^2＋ of the supersaturated calcium carbonate solution. The quantitative experimental data reveal that the scale could be reduced with the effect of magnetic treatment and the effect of the antiscale in different flow rate is different. In constant exposure time and within our concerned velocity scope in the range of 0～6 m/s, the higher flow rate ; the better effect on antiscale.
