关断脉冲;熄火脉冲
system reliability can thus be enhanced by increasing minimum turn-on pulse width and turn-off pulse width, without decreasing system specifications.
因此可以通过增加最大、最小窄脉冲宽度提高系统的可靠性,而不影响系统的性能。
Infrared light emitting diode is used to deliver appropriate light pulse with a very short turn-off time in the range of 0.5~ 1 micro-s-econd.
利用红外发光二极管作为闪光源,获得了合适的光强和0.5~1微秒的短余辉。
A patient wears the spectacles frame, turn on the switch of the pulse diathermy machine, and then can be treated by oneself whether adults or children.
病人戴上眼镜框架,打开脉冲电疗机的开关,则无论成人或小孩即可随时随地自行治疗。
