| 摘 要： | 对于在速调管中广泛使用的重入式谐振腔以及内部无漂移管的盒形腔，在忽略漂移管壁厚的前提下，导出了能够准确求解其谐振频率的本征方程，并在此基础上进一步计算了腔体的特性阻抗和固有品质因数。针对具体算例的应用表明，由解析式确定的腔体特性参数与SUPERFISH的数值结果具有很好的一致性。

| Abstract: | For reentrant and pillbox cavities widely used in klystrons,on the premise of omitting the thickness of the drift tube,we have deduced the characteristic equation for predicting the resonant frequency of these cavities accurately.Moreover,the analytical formulae for the characteristic impedance and intrinsic quality factor of cavities are found.For a concrete structure,the characteristic parameters of cavities are calculated by the formulae and the progroam SUPERFISH separately,and good agreement between the results is noticed. |
