A well-regulated power supply provides the high voltage for the photomultiplier . 一个高度稳定的电源供给光电倍增管所需要的高压。
It is therefore advisable never to use an excessively high working voltage for a multiplier cell . 因而光电倍增管不使用过高的工作电压是很有道理的。
The principle of the multipliers is as follows: a light quantum hits the lightsensitive layer and releases an electron . 光电倍增管的原理如下:一个光量子打在感光层上,释放出一个电子。
The photomultiplier converts the light energy signal into an identical electrical signal that can be easily manipulated and measured . 光电倍增管可将光能转变成易于操纵或测量的电流信号。
The old man glanced at the bearers, and then answered, with a little smile that somehow sent my blood to my heart . 老人看了那些轿夫一眼,然后微笑着答复了我的问题。他的笑容使我勇气倍增。
