中文摘要：研究了输入交流电压波形对Fe73.5Cu1Nb3Si13.5B9非晶薄带磁感应效应和磁感应效应变化幅度的影响，并研究了当输入电压为正弦交流电压时，非晶薄带磁感应效应变化幅度的重复性以及温度和湿度的稳定性。 结果表明，当输入电压为正弦交流电压时，线圈两端的感应电压也为同频率的正弦交流电压，当输入电压为矩形脉冲电压时，线圈两端的感应电压则为同频率的尖脉冲电压；其磁感应效应比输入电压为正弦交流电压的强，但磁感应效应变化幅度比输入电压为正弦交流电压的小；当输入电压为正弦交流电压时，非晶薄带磁感应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小。
英文摘要：Influences of input voltage waveform on magnetic induction effect and its repeatability of Fe73.5Cu1Nb3Si13.5B9 amorphous alloy ribbons were researched. The repeatability of magnetic induction effect and its stability of temperature and humidity with sinusoidal input voltage were also researched. The results show that the induced voltage across the coil is the sinusoidal AC voltage with the same frequency when the input voltage is sinusoidal, and the induced voltage is the sharp pulse voltage with the same frequency when the input voltage is rectangular pulse; the magnetic induction effect of rectangular pulse is stronger than that of the sinusoidal, but the repeatability of magnetic induction effect is smaller that of the sinusoidal. The non-repeatability error and influence induced by temperature and humidity are small when the input voltage is sinusoidal.
