摘　　要：通过对阴极分解温度和激活温度的合理控制,不仅使阴极的活性和发射稳定性得到显著提高,而且使管内电极除气更加彻底,改善了互作用空间电子云的分布状态,有效提高磁控管的工作稳定度,使磁控管频谱主副瓣比提高到12dB(平方率)以上。Through the reasonable control of the cathode decomposition temperature and activation temperature,the cathode activity and emission stability is greatly improved as well as degassing the electrode much more thoroughly.And the distribution of electron cloud of the interaction space is improved. So the magnetron work stability is improved very effectively,and the magnetron spectrum main to sidelobe ratio increased to 12dB(square rate above).
