查询词典 receiver

The now available long-range supervision system at home and abroad is based on the optical fiber mostly, and if the optical fiber runs into that the machinery lashes and colliding optical fiber may split or break. Once splitted, it's hard to be restored because of the sophisticated equipment, and ordinary user can't restore it by means of the welding at all. Moreover the high price of light transmitter and light receiver limits the application and popularization.

国内外现有的远程监控系统大多基于光纤，而光纤如果遇到机械冲击、碰撞等都会造成光缆断缆或断芯，光缆断裂后，很难快速修复，且修复设备复杂，普通用户根本无法进行焊接修复，再加上光端机价格较高，这些都限制了光纤远程监控系统的应用和普及。

Based on the principle of light-pen mode non-track three dimensional coordinate measuring technology, the paper uses PSD as the photoelectric receiver and point light modulated by frequency to measure coordinates.

本文通过对光笔式无导轨三坐标测量的研究、提出了以PSD(Position Sensitive Detectors，位置检测传感器)作为光电接收传感器，用高频调制光作为点光源，进行位置坐标测量的新思路，以提高整机的精度。

RELIABLE FALLING BALL DETECTION: Thanks to the wide light projector and wide light receiver, the ASP-5 detects the falling ball even if the ball falls with some angle.

特殊的光电检测设计，避免因测试球落下角度不同可能引起的误差。测试结果与手动试验结果相比，有良好的再现性，并且精度更高。

Very quickly Philo had an idea for such a receiver. It would trap light in a container and send the light on a line of electrons. Philo called it "light in a bottle."

很快，菲罗就产生了一个研制接收器的想法：在一个容器中捕捉光线，再用一条电线将光传送过去，菲罗将这称之为"瓶里的光"

At the same time, when the numbers of the needles of the umbrella-shaped conductor lightning eliminator reach the same value of the lightning receiver as said before, its corona current also reaches the ...

作者把消雷器与避雷针合二为一，获得了最佳的消雷和避雷的性能，当这种伞状导体消雷器针数处于某一值时，其电晕电流最大，消雷效果也最好。

We calculated the sensitivity, specificity, and likelihood ratio and, where possible, the Receiver Operating Characteristic curve of a cardiac event in each study.

我们计算每项研究的敏感性，特异性和可能率，可能的话还有患者心脏事件的手术特征曲线。

In recent years, with the development of the micro-electronics technique, the price of GPS receiver have been greatly falling , and as a result of the United States closing SA to stop limiting the public position accuracy of GPS , the GPS positioning accuracy have improved greatly in public field. All this consumedly promote the development of GPS in public field, and especially in the vehicle navigation field , GPS shows its superiorly navigation performance.

近年来随着微电子技术的发展使得GPS接收机的价格大幅度下降，同时美国提前关闭SA停止对民间用户精度的限制使得GPS民用定位精度有了很大的提高，这大大促进了GPS在民用领域的发展，尤其是在车辆导航领域，GPS系统充分展示了它那优越的导航性能。
