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,它们是晶体。
Only if transistor A AND transistor B are on does the output wire have current.
只有A和B导通,输出线才有电流。
The next stage was the triode, which uses a third electrode called the grid.
下一阶段是,它使用称为栅第个电。
The ability to amplify signals also made the triode crucial for radio and long distance communication.
放大信号也使对于无线电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, 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.
这些真空将成为无线电、长途电话,以及近半个世纪其他电子设备基础。
