[求助] 求翻译一段话

磁场水处理技术作为一种物理方法,集防垢与除垢、缓蚀 、杀菌,水质净化等多功能 于一体,且具有无毒无二次污染的优点,是一种极具发展前景的水处理技术。但其处理效果方面一直 存在着很大的争议,如就磁场对碳酸钙结晶过程的影响而言,有人认为在磁场作用下碳酸钙生成 晶粒的速度快,晶粒体积小,与正常条件下结晶指标相比结晶粒子也较多;也有人认为磁场作用对 碳酸钙结晶没有影响。产生这些不同的研究结论,笔者认为是由于磁场的多样性与磁场作用方式的复 杂性和特殊性所造成的。

Water treatment technology using magnetic fields, as a physical method, integrates multiple functions such as scale prevention, scale removal,  corrosion inhibition, disinfection and water purification. It has the advantage of being non-toxic and no secondary pollution and is a water treatment technology with great development potentials. There are, however, substantial controversies about its treatment effects. For example, concerning the effect of magnetic fields on crystalisation process of calcium carbonate, some people believe that under the impact of a magnetic field, the speed with which calcium carbonate forms crystal grains is high, the volumes of grains small and more crystal particles compared with crystalisation measures under normal conditions; while there are other people who do not think that magnetic fields have any effect on crystalisation of calcium carbonate. The reason why these different conclusions are reached is, in the author's view, the diversity of magnetic fields, as well as the complexity and peculiarity of the ways magnetic fields to impact.

As a physical method, magnetic water treatment technology had integrated multiple functions such as scale control, scale removal, corrosion mitigation, sterilization and water purification in a group. It also had advantages in being non-toxic and no secondary pollution which made it would be a water treatment technology with promising development potentials. However, there had been a lot of controversy over its treatment effect. For instance, in terms of concerning the effect of magnetic fields on crystalisation process of calcium carbonate, someone considered under the effect of magnetic field, the speed of calcium carbonate forms crystal grains was high, grain size was small , compared to crystalisation measures under the normal conditions more crystal particles formed; meanwhile, other people had different viewpoints at this point, they argued that magnetic fields had no effect on crystalisation of calcium carbonate. In the author's opinion, it was that the diversity of magnetic fields, as well as the complexity and peculiarity of the ways magnetic fields contributed to these different research conclusions.
