P and N-type semiconductors can also be combined in sets of three.
P 和 N 型半导体也可以集成成三管，它们是晶体管。
Only if transistor A AND transistor B are on does the output wire have current.
有三管A和三管B导通，输出线才有流。
The next stage was the triode, which uses a third electrode called the grid.
下一阶段是三管，它使用称为栅的第三个。
The ability to amplify signals also made the triode crucial for radio and long distance communication.
放大信号的能力也使三管对于无线和长距离通信至关重要。
With 18,000 triodes, ENIAC was nearly the size of a tennis court and weighed 30 tons.
ENIAC 拥有 18, 000 个三管， 几乎有一个网球场那么大，重达 30 吨。
These triode vacuum tubes would become the basis of radio, long distance telephone, and many other electronic devices for nearly a half century.
这些三管真空管将成为无线、长途话，以及近半个世纪的其他子设备的基础。
