field emission electrons的用法和樣例:
例句
- CNTs has a high aspect ratio, low work function, good electrical conductivity and nanometer tip, which can emit electrons at low voltage.
尤其是它具有大的長(cháng)徑比,低的功函數,良好的導電性和納米級的尖端,使其能夠在相對較低的電壓下就能長(cháng)時(shí)間地發(fā)射電子,因此被認為是一種優(yōu)良的場(chǎng)致發(fā)射陰極。 - They can also emit electrons,so they can be used in ultrathin display screens.
它們也能發(fā)射電子,因而能用于極薄的顯示屏。
