摘　　要：大功率行波管用均衡器通常工作环境恶劣,需要满足在高、低温度环境中均能正常工作的要求。针对如何提高均衡器的宽温稳频特性,文章中先建立均衡器同轴谐振腔单腔模型,应用三维分析软件对模型进行分析,经过参量变化,灵敏度分析,并与理论分析相结合,得到物理尺寸设计限制范围。以此指导均衡器的调试,使均衡器温度稳定特性得到提高,验证了灵敏度分析方法在实际应用中的有效性。The equalizer used in high - power traveling - wave tube usually works in bad environment, even at quite high or low temperature. Aiming to temperature characteristic of equalizer, a single resonance cavity substructure model is set up in this paper. A range of physical sizes is ascertained by parametric sweep, sensitivity analysis and theoretical analysis, which is used to meliorate temperature characteristic of equalizer. The method of sensitivity analysis has been used to guide us to debug equalizer, which proved to be efficient in the related experiment.
