双电子束 meaning in Chinese

twin-cathode ray beam

Dual channel oscilloscope
双电子束示波器
A virtual cathode oscillator with an axially extracted te10 or te11 mode has been investigated using the pic code . it can emit microwaves axially through an antenna without mode converter or transition waveguide , making the system more simple and compact . the efficiency of this device can be enhanced by employing premodulation cavity , resonant cavity , feedback mechanism , and virtual cathode formed by two electron beams
本文利用物理分析和粒子模拟的方法研究了轴向提取te10 / te11模虚阴极振荡器,结果表明通过引入预调制腔、谐振腔、反馈端面、双电子束阴极等结构,可以实现结构相对紧凑、束波转换效率较高的轴向提取虚阴极振荡器。
