sensor threshold

DNA damage sensor can not be activated when dose or dose-rate decreases to certain threshold, cell death induced by radiation will increase, it will show hyper-radiosensitivity.

剂量或剂量率下降到一定域值则不能激活DNA损伤感受器，从而导致射线对细胞的杀伤作用增强，表现出超放射敏感性。

This method uses a linear CCD as photoelectric sensor. After binarized processing, CCD output signal is stored with high speed in SRAM, then finished the data gathering function. The binarized threshold signal is provided by the software through digital potentiometer.

该方法采用线阵CCD作光电传感器，CCD输出信号经二值化处理后采用静态存储器进行高速存储，完成数据采集的功能，且可通过数字电位器用计算机软件提供二值化阈值信号。

Through the comparison between methods of fire alarming, the authors proposed to use the UV sensor as the detecting component, and to select the threshold value by applying intelligence.

采用紫外火焰传感器作为火灾检测的传感元件，系统不但具有声光显示、报警的功能，而且还具有传感器自检、与快速成形机的控制计算机进行通讯等功能；
