摘　　要：对二能级原子与单模辐射场相互作用系统的哈密顿量进行了分析,找出了光场与原子之间耦合系数与光场频率及谐振腔体积之间的关系。通过利用谐振腔的腔镜振动机制,研究了腔镜振动对光场模式及腔体积的影响,最终找出辐射场与原子之间耦合系数与场频变化之间的关系。The interaction Hamiltonian of a two-level atom and a single-mode radiation field with time-varying frequency is analysed. The special attention is paid on the relationship between the atom-field coupling and frequency of cavity field or volume of cavity. By using vibration mechanism of cavity mirror, the impact induced by vibration of cavity mirror on the optical mode inside the cavity and volume of cavity is studied, and the exact relationship between the time-varying frequency of cavity field and atom-field coupling constant is found.varying-frequency field; vibration of cavity mirrors
