同时还指出，预群聚有在不增加电子束能量情况下缩短激光波长和降低对电子束质量要求等作用。
It is also indicated that prebunching can short the laser wavelength without increasing the electron beam energy and relieve the requirement on the electron beam quality.
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 role of the space charge wave is that it makes bunching reduce at small signal, but it makes bunching enhance at large signal.
