The corresponding electric currents are used to deflect an electron beam in a cathode-ray tube . 相应的电流就用来使阴极射线管里的电子束偏转。
As the electron beam goes across the face of the picture tube, there are various little spots of light and dark . 当电子束扫过显象管屏幕时，屏幕上就有许多小亮点和暗点。
The secondary backscattered electron current is used to modulate the intensity of an electron beam in a cathode ray tube(crt) . 二次电子或背散射电子的电流被用来调制阴极射线管（CRT）中电子束的强度。
