高频电磁场 meaning in Chinese
electromagnetic field of high frequency
high frequency electromagnetic field
Examples
- Occupational exposure limit for high frequency field in the work environment
作业场所高频电磁场职业接触限值 - The antenna investigated in the dissertation is the unilateral slot antenna with fed taper and end taper , which is fed by fin - line
最后借助于三维高频电磁场仿真软件ansofthfss ,对整个鳍线馈电线性渐变天线系统进行了优化。 - As well - known , there is an induced current on the surface when metal material is in the high frequency electromagnetic field , since tending to skin heating effect to make the temperature of metal material surface go up promptly , surface beginning melt when temperature reaches the melting point of metal , metal material is heated up continuously by surface to core till the metal droplet of melting
自悬浮定向流技术制备金属纳米微粒与一般的蒸发冷凝法有所不同，其原理是：金属材料在高频电磁场中产生表面感生电流，由于趋肤加热效应使得金属材料表面的温度迅速升高，当温度达到金属的熔点时表面开始熔化，通过热传导作用金属材料由表面到芯部不断加热直至熔化成金属液滴。 - Electron gun is the foremost parts of twt , it can produce electron beam with a certain shape and current , in order to guarantee the reliability and security of work , it ’ s design have to meet to the requirement not only of electric parameter , but also all kinds of subsidiary characteristics such as filament pyrogenation efficiency , warm up time , shape size , pole space capacitance and the ability to be able to bear the press and all kinds of rigorous run conditions such as high temperature , high humidity , low air pressure , strong vibration and great strike
由于行波管的大功率和高频率等特性,目前还没有任何其他的器件可以代替。行波管是应用高频电磁场与电子注进行互作用的机理进行工作的,而电子枪是行波管中产生电子注并使它成型的基本部件,电子枪的结构设计决定了枪体自身必须具有良好的抗振可靠性,否则结构发生共振或振动位移过量,就会导致行波管的失效。因此对行波管电子枪的研究具有非常重要的意义。
