摘　　要：利用含电流的传输线方程 ,在考虑多模与电子注互作用及多模耦合的情况下 ,对三次谐波渐变复合腔回旋管进行了非线性模拟 ,计算了H51 H52 模式下三次谐波注波互作用 ,分析了多模对注 波互作用的影响 .Starting from the general transmission line equation with an electron beam, a self\|consistent nonlinear analysis on complex cavity gyrotron with gradual transition is presented, in which the multiple modes interacting with an electron beam and the mode coupling are taken into account. The interaction between the electron beam and H 51 H 52 RF field for third\|harmonic gyrotron is simulated numerically. The influences of multiple modes on the interaction are analyzed.
