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.
从负能空间电荷波与电磁波耦合的物理图像出发推导了喇曼散射模式自由电子激光器耦合频率的解析表达式。

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。
