摘　　要：　从改善圆盘加载波导作为相对论行波管慢波结构的特性入手,加入同轴内导体,着重研究其小信号理论。利用场匹配法导出了"热"色散方程并计算求解,具体分析了系统的电子注参量及慢波结构几何尺寸对小信号增益及慢波相速的影响,为同轴圆盘加载相对论行波管的设计提供了理论基础。This paper presents the study on the coaxial disk-loaded waveguide as the slow-wave structure of the relativistic traveling wave tube(RTWT). The inner conductor is employed in this structure to improve the characteristics of such slow-wave system. The small-signal analysis of the RTWT with coaxial disk-loaded waveguide was emphasized, and the influences of the beam parameters and the structure dimensions on the small-signal gain and phase velocity of slow-wave were described. The results provides the theoretical basis for the design of the coaxial disk-loaded RTWT.
