摘　　要：本文讨论了开槽圆柱波导的高频场分布，给出了注波互作用自洽非线性理论．在电子作大回旋运动与考虑速度零散的情况下，采用四阶龙格库塔法，对均匀截面开槽波导3次谐波回旋行波放大管往波互作用进行了数值计算，得出一些重要的互作用规律，为回旋行波放大管的进一步研究打下了基础．The distribution of RF field of the slotted cylindrincal wave guide is discussed and the self-consistent nonlinear theory of the beam-wave interaction is prasented in this paper. The behavior of the slotted gyroton travelling-wave amplifier (gyro-TWT) with a uniform section is simulated by a Runge-Kutta algorithm code for a warm beam encircling around theaxis of the wave guide. Some important regulations are obtained. This work presents the bases to further studies of the pyroTWT.
