Three - dimensional computational simulation for high - frequency characteristic of helical slow - wave circuit 螺旋慢波电路高频特性的三维计算模拟
Preliminary experimental research on relativistic high power microwave generator with coaxial slow wave structure 同轴慢波结构相对论高功率微波产生器初步实验研究
In this situation , folded groove guide sws is proposed and studied in this dissertation . 2 二、分别介绍了曲折波导慢波结构和槽波导传输线的研究方法和理论进展。
So , one can conveniently design a high performance sinuous feed rapidly following the steps in this paper 因此，根据文中步骤可以快速、方便地设计出性能优越的波导慢波线。
Sws is the key part of the rbwo and rtwt , whose characteristic could determine the speciality of rbwo and rtwt 慢波结构是rbwo和rtwt的关键部件,其性能直接决定了rbwo和rtwt的性能水平。
The tm01 mode of the coaxial bwo has no cut - off frequency , which is similar to the tem mode in the conventional coaxial waveguide 这是因为同轴慢波结构的tm01模式有类似于tem的性质,没有截止频率。
Within an hour of a person falling asleep , slow waves will have covered his entire cortex , affecting every nerve cell in it 在人入睡后的一小时内慢波将覆盖其整个大脑皮层，并影响其中的每个神经细胞。
Periodic structure ( ps ) has been used in many applications such as slow wave structure ( sws ) and frequency selective surface 周期电磁结构有着广泛的应用,常被用作频率选择表面或者高功率微波器件中的慢波结构等。
The bandwidth of this kind of twt can reach 30 - 40 % if choosing the optimal parameters of the structure and the beam 因此，合理选择慢波结构几何尺寸和电子注参数，具有中心导体轴螺旋槽行波管的相对工作带宽可以达到30 ? 40 。
The slow wave sleep in the process by the central cortex inhibition , jade pillow can reduce cerebral blood , central nervous get enough rest 人的睡眠在慢波过程中脑皮层中枢受抑制，玉枕可以减少脑供血，使中枢神经得到充分休息。
