conduction band的用法和樣例：
例句
- The highest-energy band containing electrons is called the valence band, and the next higher one is the conduction band.
填有電子而能量最高的能帶稱(chēng)為價(jià)帶，相鄰的更高能帶稱(chēng)為導帶。 - Thus, optical-wavelength light can excite an electron at an impurity atom from one discrete state to another without knocking it all the way to the conduction band.
因此，一般的光波可以將雜質(zhì)原子里的電子從一個(gè)離散的能態(tài)激發(fā)到另一個(gè)，而不會(huì )把它打到更高的導帶。
