介质棒 meaning in Chinese
dielectric rod
Examples
- By a large amount of calculations , the influence of the structure dimensions and the dielectric parameters on dispersion characteristic and coupling impedance of this kind of slow - wave structure is obtained . then , the linear beam - wave interaction theories of the arbitrarily - shaped helical groove waveguide and the dielectric into the arbitrarily - shaped helical groove waveguide are deduced . by the numerical calculations , the relationship is got between the small signal gain , bandwidth , electromagnetic " hot " velocity and the electronic beam , the structural parameters
通过数值计算,获得了此类慢波结构的色散特性和耦合阻抗随结构几何尺寸和介质参数的变化规律;在此基础上,建立了任意槽形螺旋槽及中心加介质棒的任意槽形螺旋槽行波管的注-波互作用线性理论,并编制程序,计算了管子的小信号增益、带宽、电磁慢波的“热”相速与电子注参数、结构参数之间的关系,获得了增加带宽或增益的途径。
