本文用蒙特卡罗计算机模拟方法模拟了水溶液的成核过程和晶体生长过程，研究了外加磁场对结晶过程的影响，较成功地解释了磁效应与磁感应强度的多极值关系和磁防垢的机理。 In this paper, the nucleation process and crystal growth process of aqueous solution were simulated by computer simulation of Monte Carlo method. The influence of applied magnetic field on the crystallization process was studied. The multi-extremum relationship between magnetic effect and magnetic induction intensity and magnetic anti-scaling mechanism.
