摘　　要：针对连续波核磁共振实验装置中能够产生直流偏置的多模式交变信号功率源的原有设计中,所选择的传统磁铁笨重且造价高昂的缺点,本文提出了一款稳定、操作简单快捷的新型磁铁控制功率源.这样不仅增强了实验参数设置的灵活性,而且拥有更多的参数和模式,适合在物理实验中推广应用.Because of its high cost and weight of traditional continuous wave nuclear magnetic resonance experiment, this paper presented a new magnet power source that is stable and easy in controlling. The power source can produce multi--mode DC bias alternating signal, which not only enhanced the flexibility of the experimental set of parameters, but also had more parameters and models suitable for popularization and application of physics experiments.
