bombardment by ions

基本解釋

The nucleation enhancement by the negative biased substrate is believed to be a result of the electron emission and ions bombardment.
研究表明，負襯底偏壓增強成核主要是發(fā)射電子和離子轟擊的結果。
While rf power increases to a certain value , the secondary electrons generated from cathode by positive ions bombardment lead to the enhancement of plasma optical emission.
而在放電功率升高的過程中，離子轟擊陰極產生的二次電子發(fā)射效應導致了光發(fā)射譜強度急劇增強的轉變。
