directional emittance是什么意思


中文翻译定向发射度

网络释义

1)directional emittance,定向发射度2)collimation,定向发射3)directional emittance,定向发射率4)beam transmitter,定向发射机5)directional emitter,定向发射体6)traverse emittance,横向发射度

用法例句

    Generation and collimation of hot electrons;

    超热电子的产生与定向发射

    A statistical model to calculate the directional emittance of the real surface is successfully built with the assumption that the real surface is formed by multiple Vgrooves whose walls slopes are taken to have a normal statistical distribution.

    首先应用经典的电磁场理论对光学表面在远红外波段的定向发射率进行了计算,然后将实际表面模化为由各种不同倾角的V槽按正态分布随机组成的表面。

    In order to decrease the energy spread and to get a small traverse emittance as well as high brightness of the electron beam in the injector of the FEL, a cell s microwave gun scheme adopted the technique of the harmonic cavity is presented.

    为了使自由电子激光器的电子束注入器具有小的能散,小的横向发射度、高的亮度,本文提出在 腔的微波电子枪中采用混频腔技术,并用解析方法研究了混频加速的 腔方案的动力学特性,所导出的表达式说明此方案能改善束流的纵向和横向粒子动力学性能;为了对比,还借助于PARMELA程序对此方案进行了束流动力学模拟,结论与导出的解析表达式结果一致。
