摘　　要：在引导磁场无限大的情况下,对平板波导中带状电子注进行理论分析,得出了行列式形式的色散方程并进行数值计算。研究了空间电荷波色散曲线随电子密度、电子注厚度和电子注能量等参量的变化规律,这些规律对带状注器件的研究具有一定的参考价值。Under the circumstances of infinite guiding magnetic field, the model of sheet electron beam in slab waveguide has been analysed, we obtained the determinant form of dispersion equation and numerical calculation also has been developed. Through analysis of the relationship of dispersion characteristics of the space charge wave with the electron density, the thickness of the electron beam and the energy of electron beam and so on, provide certain reference value for the study of sheet beam devices.
