摘要 本文利用二波理论对三种典型实用的非均匀输出线路的返波起振电流进行了研究并得出相应结论 .分析不仅适用于弱的渐变线路 ,也适用于中等及较强的线路渐变 ,为研究宽带高功率行波管提供了重要的设计依据 . Using two wave theory the start oscillation currents of backward wave oscillations(BWO) with three kinds of typical practical non homogeneous output circuits are analyzed and some corresponding conclusions are made.The results are applicable not only in weakly tapered circuits but also in those strongly tapered circuits.Furthermore some important principles for the design of high power traveling wave tubes are given.
