摘要
利用自制装置将音叉的振动转换为感应电流,使用数字信息化系统(DIS)微电流传感器,变更测量参量,从而测定出待测音又的频率.
Using self- made device will fork vibration is converted to an induction current of vibration, the use of digital information system ( DIS ) micro current sensor measurement parameters change, in order to determine the measured tuning fork test of frequency
