The laser ultrasonic nondestructive testing system include detecting of the light signal , amplification , demodulation and signal processing 激光超声无损检测系统主要包括光信号探测、信号放大、信号解调以及后续的信号处理等几个部分。
Thus altered , the crystals could form components for optical networks , such as a device that channels light signals around corners with very low loss in energy 如此一来,这些晶体可做为光网络的元件,例如即将出现的超低耗能光讯号导引器。
We do not have statistics on cases where pedestrians were knocked down by vehicles due to failure to cross the road before the traffic light signals changed 我们没有就因未能在交通灯号转变前及时横过马路而遭车辆撞倒的个案数字作出正式的统计。
Signals given by a police officer , traffic warden , tunnel officer or other authorized person take precedence over all traffic signs and traffic light signals 在有交通标志或灯号的地方,如有警务人员交通督导员隧道人员或其他授权人士发出信号,则应遵照他们的信号指示。
Led , short for semiconductor emitting diode , made of semiconductor , can convert electric power into light energy and convert electricity signals into light signals Led全称为半导体发光二极管,采用半导体材料制成的,直接将电能转化为光能、电信号转化为光信号的发光器件。
Accordingly , the study on the characteristic of penetration of laser beam through the atmosphere is significant basis in choosing laser lamp - house and the receiver of light signals ( i . e 因此,研究激光大气传输特性是我们选定激光光源和光信号接收器(即ccd器件)的重要依据。
To detect the light signal from the planet alone , scientists first used spitzer to measure the combined spectrum of the star and planet when the planet was close by the star 为了探测到星系行星单独的光信号,当行星靠近主星的时候科学家们先用“斯必择”测量恒星与行星混合的光谱。
For five years , those “ eyeballs ” watched for telltale flashes of light signaling a rare neutrino interaction within the detector volume , and the scientific results made headlines 五年来,这些眼珠子看遍侦测器在微中子偶尔交互作用后闪出的光讯号,其科学成就也多次上了头版。
The expression of light signal transmission factor phya i s different in the two cultivars . phya gene expressed only in light - interrupted part of light - dependent " tsuda " turnip 而光信号传递因子中phya的表达在两种品种试材中存在差异,只有光敏感型津田芜菁暗处理的试材中有表达。
