As the sensory unit, the vibrator of grating sensor is designed to measure micro-vibration, and transform the vibration of ground into light modulating signal-Moir é fringe, and then, change into digital signal by photoelectric elements. 光栅传感器以光栅谐振子作为敏感元件,将大地震动的机械信号转换成光调制信号&莫尔条纹,再用光电元件转换成数字化电信号输出。
Meanwhile, the data control unit and data sensory control unit and Active Data Object access technology are applied while establishing the database. 在数据库设计的同时使用到数据控件和数据感知控件以及ADO数据对象访问技术。
Electrophysiological, there were sensory conduction velocity slowing, amplitude decrement of nerve action potentials, abnormal spontaneous activities and increased polyphonic motor unit potentials. 神经电生理检查显示神经传导速度减慢,波幅降低,异常自发电位(纤颤电位和正锐波),运动单元多相电位增加。
To ensure safety of electrical power systems, various of temperature sensors and temperature monitor systems have been developed among which temperature sensor using optic-fiber as sensory unit is the mainstream model. 为保障电力系统可靠运行,业内人士已经研制了各种各样的温度传感器及温度监测系统,其中以光纤作为敏感元件的温度传感器已经成为电力温度监测系统的主流模式。
