摘　　要：在前期铷原子钟微小型化的研究基础上,针对用于承载量子部分的介质谐振腔,利用格林函数法研究电激励下谐振腔频率变化情况,实际加工谐振腔及其激励探针,测量出介质谐振腔在该激励下的谐振情况。结果表明,当选择50Ω同轴线探针,对谐振腔进行电激励,能够激发出TE101模式,谐振频率达到6.83GHz,电磁场分布均匀。该激励方法经济成本低、激励效果较好,适用于小型铷原子钟。Based on the research on the microminiaturization of the rubidium atomic frequency standard, the Green function method is used to study the frequency change of the microwave cavity under electric excitation. Based on these, the microwave cavityand its excitation probeare manufactured, and the resonance condition of the dielectric resonator under this excitation is measured.Tested results demonstratethatthe TE101 mode is excited when the 50Ωcoaxial probe is used to stimulate the resonator. The resonant frequency can reach 6.83 GHz and the electromagnetic field is evenly distributed. The excitation method is low in processing cost and good in excitation effect, and is suitable for the rubidium gas chamber type micro atomic frequency standard.
