bombardment of electrons

基本解释

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.
而在放电功率升高的过程中，离子轰击阴极产生的二次电子发射效应导致了光发射谱强度急剧增强的转变。
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.
吸气材料的加热可以利用加热导线或通过散射电子（322）对包括吸气材料的电极（341、342）的限定轰击来实现。
