摘　　要：将谐振腔的微扰理论应用于均衡器子结构中,结合均衡器结构参数变化引起的均衡器电参数特性变化机理,提出了采用微调螺钉结构补偿方法对由于温度变化引起的频率漂移进行改善,并以单腔子结构为例,进行HFSS仿真和相关实验验证,证明了该方法对改善均衡器温度特性较为有效。A perturbation theory of electromagnetic fields is used in the coaxial cavity equalizer. Relating with the analysis on the change of physical parameter in equalizer working on electrical parameter, the method of structure compensation by metal bolt is put forward to meliorate the frequency excursion caused by temperature change in this paper. With single cavity structure as an example, the means is proved feasible aiming at temperature characteristic in equalizer debugging according to HFSS and the related experiment .
