论述大耦合孔对相对论速调管谐振腔的电场分布和特性参数（包括谐振频率、品质因数、特性阻抗、耦合系数等）影响的简要的理论分析与实验研究，以及相应参数的测试方法，并提出了新的耦合孔结构，解决了大耦合孔对谐振腔谐振频率、耦合系数、径向、圆周方向的电场分布的不良影响，其结果对高功率微波器的设计有重要的参考价值。

The influence of large coupler on the cavity paramters of relativistic klystron amplifier is described in this paper.The parameters include the plots of electron field,resonance frequency, Q value,characteristic impetance,and coefficience of coupler.A new coupling structure is designed to resolve the influence,especially the resonance frequency,coupling coeficience and the plots of eletron field.The results is very important for the device design of high power microwave.
