摘　　要：采用数字存储示波器实测了一种家用低频电治疗机的7组波形和一种医院用低频电治疗机的1组波形。结果显示各种功能低频电输出波形由基本的脉冲波以不同的重复方式构成。两台被测治疗机的基本脉冲波波形相差不大,同功能的低频电输出波形不同。建议进行低频电治疗研究时应给出所用低频电的波形。The digital storage oscilloscope was used to measure 7 groups of waveform of one family electric machine and one group of waveform of one hospital low frequency electric machine. The results show that the difference of the single pulse waveform between two types of low frequency electric machines is not significant. Various outputs of the low frequency electric machines are compgsed of the single pulse in different repeated ways. The waveform of the same outputs in two electric machines is different. Therefore, it is necessary to display the waveform of the low frequency electricity in low frequency electric treatment.
