例句與用法

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
基本的顯微鏡包括一個電子源和一塊以垂直的柱形排列的磁性透鏡集成板，板上排列的間隔為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
氧化鋅是一種非常優(yōu)異的多功能半導(dǎo)體材料，氧化鋅納米線具有很多新穎的光學(xué)與電學(xué)特性，它在電子學(xué)領(lǐng)域的用途之一是作為場發(fā)射電子源。
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,場致發(fā)射陣列陰極的應(yīng)用領(lǐng)域十分廣泛,主要包括微波器件(應(yīng)用于twts , klystron等) 、平板顯示器( feds ) 、電子顯微鏡及電子束刻蝕系統(tǒng)等。其中,應(yīng)用研究的焦點主要集中在平板顯示器和射頻功率放大器。
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
碳納米管具有準(zhǔn)一維的結(jié)構(gòu)、良好的導(dǎo)電能力、化學(xué)穩(wěn)定性和機械強度,由于其極高的長徑比而且能在較低的宏觀電場下發(fā)射電子,因此被認為是較為理想的場發(fā)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光源的基本特點是采用熱電子發(fā)射形式即采用熱燈絲作為電子發(fā)射源，在高壓加速下轟擊陽極產(chǎn)生x射線，這樣的光源體積較大，需要加熱陰極的電源，且對頻率響應(yīng)慢。
