| 摘 要： | 在相对论情况下，导出了速调管(klystron)和契伦柯夫(Cherenkov)器件中考虑空间电荷波影响的被调制电子束的谐波电流公式；并且分析了空间电荷波对电子束群聚的影响：在小信号时使群聚减小；在大信号时使群聚增强。

| Abstract: | Using a relatively strict method, the formulas of the harmonic current of the modulated electron beam in the klystron and Cherenkov devices were derived in the relativistic regime,in which the effect of the space charge wave was taken into account. The role of the space charge wave is that it makes bunching reduce at small signal, but it makes bunching enhance at large signal. |
