常見(jiàn)例句雙語(yǔ)例句Then the cathode current density can be obtained from the processed emission current density distribution curve.因此本方法可直接對(duì)實(shí)用顯象管推出陰極有效發(fā)射區(qū)中的電流密度分布。This paper presents the CVD growth and the field-emission of carbon nanotubes as a large current density cathode.研究了碳納米管作為大電流密度場(chǎng)發(fā)射陰極的CVD生長(zhǎng)情況與場(chǎng)發(fā)射性能。Finally we discuss the differences of turn-on voltage , field emission current density and the stability of field emission display because the differences of the cathode of field emission.并討論由此而導(dǎo)致的開(kāi)啟電場(chǎng)的變化、場(chǎng)發(fā)射電流密度的變化以及亮度和穩(wěn)定性的變化。physics.zju.edu.cn 返回 cathode emission current density
