摘　　要：利用含电流的传输线方程 ,在考虑了诸多实际因素影响的情况下 ,对三次谐波渐变复合腔回旋管进行了自洽非线性模拟 ,计算了H51 1 H52 1 模式下三次谐波多模注波互作用 ,分析了电子注的厚度、速度零散。Starting from general transmission line equation with an electron beam, a self-consistent nonlinear simulation on third-harmonic complex cavity gyrotron with gradual transition is presented, in which some practical factors are taken into account. The interaction between the electron beam and H-511-H-521 RF field for third-harmonic gyrotron is simulated. The influences of the thickness and the velocity spread and the velocity ratio of the electron beam and the fluctuation of the magnetic field on the multi-modes interaction with an electron beam are analyzed.
