同轴结构 meaning in English
coaxial configuration
Examples
- The two layers glass tube , with same axis is vacuumized between them , the vacuum degree can reach 5x10 - 2pa
双层玻璃同轴结构，夹层抽真空，管内长期维持在5x10 - 2pa高真空 - Because the coaxial structure can broaden the bandwidth , they might be one type sws of the high power capacity and the middle bandwidth . several major and valuable achievements are listed as the followings : 1
其有别于普通膜片加载波导的同轴结构，使得带宽得以拓展，因此很可能成为一类同时满足高功率容量和宽带要求的慢波结构。 - Those filaments self - organize in coaxial structures where the relativistic current in the center is surrounded by intense magnetic field and the return current sheath , and the magnetic field decreases abruptly to zero outside the relativistic current
电流丝自组织形成同轴结构，束流被强磁场和回流鞘层包围，磁场在电流丝外迅速衰减到0 。 - It is paid attention to that the longitudinal component of electric field of the coaxial tm01 mode can be strong , differing from the tem mode in the conventional coaxial waveguide . so the coaxial tm01 mode can have much strong interaction with the electron beam
值得注意的是,与普通同轴结构tem波不同,同轴慢波结构tm01模式的纵向电场不为零,这是同轴返波振荡器中的电子束能够与它有强相互作用的重要原因。 - The mode competition is much improved . it may operated with a large electron beam radius , that means decreasing the space charge effects compared with a smaller radius beam with the same current , hence the rbwo may operated with a low axial guide magnetic field . besides , the rbwo with a sinusoidal corrugated coaxial structure is very easy to manufacture
波纹内导体rbwo具有一些突出优点:同轴结构中内导体的存在使系统的截止频率显著升高,使得系统尺寸可比普通波纹波导慢波系统大;具有很大的抑制模式竞争的能力和很高的功率容量;可以采用大半径电子注,在工作电流不变的情况下空间电荷效应大幅度降低,因而可以工作在低磁场状态;此种慢波结构内导体上的波纹易于加工。
