摘要：

基于自制CaCO₃溶液临界过饱和度实验装置，通过测量加磁与未加磁对比实验的碳酸钙溶液电导率-滴定液容积，研究了电磁场作用对CaCO₃过饱和度及成核诱导期的影响。在不同频率的电磁场作用下观察了CaCO₃过饱和度及成核诱导期的变化，大量实验结果表明：在电磁场作用下，CaCO₃的过饱和度减小，成核速率加快，成核诱导期减小。

Abstract:

Based on the self-made experimental device used for measuring the critical supersaturation of CaCO₃ solution, the effects of electromagnetic field action on the CaCO₃ supersaturation and nucleation induction period has been studied by comparative tests with magnetism and without magnetism on calcium carbonate solution conductivity-titration fluid volume. The influence of magnetic field effect on CaCO₃ on the supersaturation and nucleation induction period is studied. The changes of CaCO₃ supersaturation and nucleation induction period, under different frequencies and magnetic fields action, are observed. A large number of experimental results show that under the action of electromagnetic field, the supersaturation of CaCO₃ decreases, nucleation speed increases, and nucleation induction period decreases.

Key words: electromagnetic fields, induction period, nucleation, supersaturation
