摘　　要：对两级开槽回旋行波放大管注波互作用进行了自洽非线性数值计算，详细分析了分隔段的长度、位置以及第一级、第二级高频波导的长度对注波互作用的影响规律，同时还模拟了直流磁场、电子注速度离散对注波互作用的影响情况。电子注的运动为绕轴大回旋运动。The behavior of a two stage slotted gyro TWT is self consistently simulated by a single wave nonlinear code .The effects of length and position of sever and the lengths of first and second sections on beam wave interaction are envaluated and discussed in detail.The influence of direct current magnetic field and electron beam's velocity spread on the beam wave interaction are also simulated and discussed.The electron beam encircles around the axis of wave guide .
