摘　　要：建立了具有模式变换渐变段的复合腔回旋管的自洽非线性理论，编制了高次回旋谐波注一波互作用计算程序，对三次谐波注一波互作用进行了数值模拟，并且分析了多种因素对工作状态的影响。This paper presents an application of self-consistent field theory for complex cavity gyrotron with gradual transition. In this model, the RF field profile function satisfies a wave equation in which AC beam current appears as a source. The wave equation is solved simultaneously with the electron equations of motion. A three harmonic 8 mm compleX cavity gyrotron working in H61-H62 modes is solved numerically.Rather high interaction efficiency is achieved.
