摘　　要：研究了输入交流电波形和非晶薄带片数等对Fe_(73.5)Cu_1Nb_3Si_(13.5)B_9非晶薄带磁电感效应和磁电感效应变化幅度的影响,以及当输入电压为正弦交流电压时,非晶薄带的磁电感效应变化幅度的重复性和温度、湿度的稳定性。结果表明:磁电感效应随着非晶薄带片数的增多而增强,随着磁场强度的增大而减弱,正弦交流电压比三角交流电压的强;磁电感效应变化幅度随着非晶薄带片数的增多而减小,在不同频率下正弦交电压和三角交流电压的强弱发生变化;当输入电压为正弦交流电压时,磁电感效应变化幅度的不重复性误差很小,且受温度和湿度的影响很小。Influences of the input AC wave shape and amorphous ribbon number on magnet-inductive effect and rangeability of magnet-inductive effect of the Fe73.5Cu1Nb3Si13.5B9 amorphous ribbons were studied. When the input voltage was sinusoidal AC voltage, the repeatability of rangeability of the magnet-inductive effect and stability of the temperature and humidity were studied. The results show that the magnet-inductive effect increased with the increase of ribbon number, while decreased with the increase of magnetic field intensity and the one with sinusoidal AC voltage was stronger than that with triangle AC voltage. The rangeability of magnet-inductive effect decreased with the increase of amorphous ribbon number, and the sinusoidal AC voltage and triangle AC voltage changed under different frequencies. When the input voltage was sinusoidal AC voltage, the error of non-repeatability of the rangeability of magnet-inductive effect was very small, and was hardly influenced by the temperature and humidity.
