electron emitter meaning in English
电子发射极
电子发射体
Examples
- Sed surface conduction electron emitter display
表面传导电子发射显示 - Standard practice for definition and determination of thermionic constants of electron emitters
电子发射极的热离子常数定义和测定的标准实施规范 - Due to their high aspect ratios and small tip radii of curvature , carbon nanotubes possess marvelous electron field emission properties , viz . low turn - on voltage ( e0 ) and large emission current density ( je ) , and have good potential for using as materials in electron emitters of flat panel display
由于奈米碳管具有极高的纵横比与极小的尖端曲率半径，因此奈米碳管有著超乎常态的电子场发射特性，低的场发射起始电压与大的场发射电流密度，使其为电子场发射平面显示器的良好材料。 - To find a proper and convenient way in electron emitter research , in the paper , we have discussed the essential and possibility of setting up a new pld ( pulsed laser deposition ) device which connects with aes ( auger energy spectra ) , and built such device in order to complete cathode deposition and analysis without exposing to the atmosphere and carried out cathode in - situ preparation and analysis electron emission phenomenon is a physical process taken place in surface of electron emitter
为了解决电子发射体(阴极)研究方法中存在的问题，并寻求一种适当的、方便的阴极研究实验方法，本论文论证了建立与aes相连的pld装置的必要性和可行性，并实际建立了这一装置，实现了阴极的原位沉积、原位分析。电子发射现象是在电子发射体表面发生的物理过程，发射表面是由活性元素构成的动态平衡系统，这一系统直接决定电子发射性能。表面分析手段对阴极研究是必不可少的。
