| 1. | In electronic detectors such as photomultipliers and television tubes, noise manifests itself as random fluctuations in the output current .
对于光电倍增管，电视摄像管之类的电子探测器，噪声则表现为输出电流的随机起伏。 |
| 2. | The limitations of this scheme became quite apparent with the introduction of detectors such as the plumbicon, image orthicon and vidicon .
这个方法的局限性在引进诸如氧化铅光导管摄像管，超正析象和光导摄像管之类的探测器之后变得很明显。 |
| 3. | Radiation image pickup tube
辐射图像摄像管 |
| 4. | Slow scan vidicon
慢扫描光导摄像管 |
| 5. | The energy density of the spot was 100 times the typical saturation level of the vidicons
光点的能量密度为光导摄像管典型饱和电平的100倍 |
| 6. | Harmonized system of quality assessment for electronic components - generic specification : camera tubes
电子元器件质量评定协调体系.通用规范.摄像管 |
| 7. | Harmonized system of quality assessment for electronic components - blank detail specification : camera tubes
电子元器件质量保证协调体系.空白详细规范.摄像管 |
| 8. | The television camera also looks at a scene as a series of dots ; each dot of light is translated by the camera tube into an electronic signal
电视摄像机也是把景象看成一系列的点，每一个光点都被摄像管转换成一个电子信号。 |
| 9. | In place of the single camera tube of the black and white camera , it has three tubes - - one for each of these colours - - and the signals produced by them correspond to the amount of each colour
在黑白摄像机的单摄像管的地方，彩色摄像机有三根管? ?一根对一种颜色? ?它们产生的信号与每种颜色的数量一致。 |
| 10. | In both radio and television receivers , once the basic signals have been separated from the carrier wave they are fed to a loudspeaker or a display device ( usually a cathode - ray tube ) , where they are converted into sound and visual images , respectively
在无线电和电视两个接收器中，一旦基本信号与载体电波分离，即被供于扩音器或显示设备(通常是阴极摄像管) ，在那里它分别被转换成声音和可视图像。 |
