摘要
本文严格证明了任意截面波导内,由电子注电流激起电磁场的过程中的能量守恒关系,改正了作者在文章[1]中的一些错误;并把它推广到一端短路的波导系统。这一结果说明了能量守恒是麦克斯韦方程组的固有性质。
The energy conservauon in the radiation process by electron beam in a waveguide with arbitrary cross-section is proved. Some mistakes in Ref. [1] by myself are corrected. And the results are extended to the waveguide system with one shorted end. This result explains that the energy conservation is the intrinsic attributes of the Maxwell's equation set.
