The role of the spacechargewave is that it makes bunching reduce at small signal, but it makes bunching enhance at large signal.
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。

The theorem of relativistic kinetic energy has been derived, and the normalized model of relativistic spacechargewave is derived as well.
导出了相对论电子注的动功率流定律,求得了相对论空间电荷波的正规模式。

Analytical expressions of coupling frequencies of Raman free-electron lasers are deduced based on the physical image of the coupling between negative-energy space-chargewave and EM wave.
