electron source meaning in Chinese
电子源
Examples
- The basic microscope consists of an electron source and an assembly of magnetic lenses arranged in a vertical column that is evacuated to about 10 torr or better
基本的显微镜包括一个电子源和一块以垂直的柱形排列的磁性透镜集成板，板上排列的间隔为10托或更好。 - Zinc oxide is a kind of excellent multi - functional semiconductor materials , zinc oxide nanowires have a lot of new optical and electronic characteristics , and one of its functions in the electronic frontier is worked as field emission electron source
氧化锌是一种非常优异的多功能半导体材料，氧化锌纳米线具有很多新颖的光学与电学特性，它在电子学领域的用途之一是作为场发射电子源。 - At present , feas have potential for use as an electron source in a wide variety of applications , including microwave power amplifiers ( such as twts , klystron ) , flat panel displays , electron microscopy , and electron beam lithography
目前,场致发射阵列阴极的应用领域十分广泛,主要包括微波器件(应用于twts , klystron等) 、平板显示器( feds ) 、电子显微镜及电子束刻蚀系统等。其中,应用研究的焦点主要集中在平板显示器和射频功率放大器。 - Carbon nanotubes ( cnts ) have attracted great attention in material science and technology for their semi - one - dimension structure , good electrical conductivity , excellent chemical and mechanical properties . especially for their high aspect ratio and emitting electron at low voltage , cnts have been considered as one of the most promising material for field electron source
碳纳米管具有准一维的结构、良好的导电能力、化学稳定性和机械强度,由于其极高的长径比而且能在较低的宏观电场下发射电子,因此被认为是较为理想的场发射材料。 - However , the most commonly used x - ray sources didn " t change much no matter in structure or theory , still using thermionic cathodes as electron sources . such conventional x - ray tubes have some defaults , such as big volume , low frequency response , demanding for supply to cathode that was also brittle
目前使用的x光源的基本特点是采用热电子发射形式即采用热灯丝作为电子发射源，在高压加速下轰击阳极产生x射线，这样的光源体积较大，需要加热阴极的电源，且对频率响应慢。
