bombardment of electrons

基本解釋

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。
A heating of the getter material may be realized with heating wires or by a defined bombardment of scattered electrons (322) onto the electrodes (341, 342) comprising the getter material.
吸氣材料的加熱可以利用加熱導線或通過散射電子（322）對包括吸氣材料的電極（341、342）的限定轟擊來實現。
