In electronics, a vacuum tube or thermionic valve or just valve, is a device generally used to amplify, switch or otherwise modify, a signal by controlling the movement of electrons in an evacuated space.
真空管是一种电子设备，由抽真空的容器组成，它具有发射电子的阴极（旁热式是由灯丝加热，直热式则灯丝就是阴极）和工作时通常加上高压的阳极。阴极和阳极之间，自阴极算起，第一个电极称为栅极，再增加一个电极则称为帘栅极。

In ancient times, when vacuum tubes were still in use, the A battery (often about 6 volts) heated the filament or cathode to boil off electrons, the B battery, positive with respect to the cathode, sucked the negative electrons to the plate, while the C battery, a few volts negative with respect to the cathode, tended to repel the electrons back toward the cathode.
古时候，还在使用真空管时，A电池（通常为6V）通过加热灯丝或阴极来蒸发电子，B电池，正极连接阴极，将负电子吸引到极板上，而C电池，只有几伏，负极连接阴极，将电子击回阴极。
