| 磁场的产生方式有永磁式与电磁式两种，电磁式又包括直流式和交流式两种，在研究中，这些不 同类型的磁场，对水系统的作用方式是否存在差异，尚未见过相关报道。笔者认为，不同类型的磁场 对水系统的作用机理可能相同，但作用方式可能并不相同，如果操作不当，磁场对碳酸钙结晶过程的 影响就不明显，以致使研究者误得出磁场作用对碳酸钙结晶没有影响的结论。如果能够找出不同类型 磁场作用方式的差异将对揭示磁场作用机理具有重要意义。本文采用永磁体磁场、直流式与两种频率 的余弦交流式电磁场分别对静态Ca(HCO3)2溶液中的CaCO3结晶过程的影响进行了对比实验研究。 |

There are two ways to generate magnetic fields, by permanent magnet or electromagnetically and the latter can be through DC or AC. Among the studies, whether there are differences in the way water systems are impacted for different types of magnetic fields, has not appeared in reports. In the author's view, although the mechanism by which different magnetic fields impact on a water system is likely the same but the ways of impact may very well be rather different. If inappropriately done, the effect of magnetic fields on crystallisation of calcium carbonate will be insignificant so that the researcher would draw the wrong conclusion that there is no effect of magnetic fields on crystallisation of calcium carbonate. If the differences in effects of different types magnetic fields ways can be found, it will have an important bearing on revealing the mechanism of magnetic fields. This paper presents an experiment where, through permanent magnet, DC electromagnetically as well as cosine AC electromagnetically at two frequencies, the effects of magnetic fields on crystallisation of CaCO3 in static Ca(HCO3)2 solution are studied respectively. 供参考 |
