利用闭合轨道理论，对原子在界面附近的自发辐射率的计算公式进行了推导，并对界面附近原子自发辐射率的多周期振荡现象进行了系统的研究。首先，根据光子的闭合轨道理论，把原子的自发辐射用经典的偶极天线辐射来模拟，推导出原子在一个金属界面旁的自发辐射率的计算公式，然后再推广到两个金属界面旁的原子自发辐射情况，并对原子自发辐射率的多周期振荡进行了分析。%We derived the formula of the spontaneous emission rate of atoms near the interfaces and discussed the multi-periodic oscillating phenomenon of the atoms near the interfaces .First of all ,according to the photon closed-orbit theory ,we simulated the spontaneous emission of atom near interface as the radiation of the classic dipole antenna ,then we derived the calculation for-mula of the spontaneous emission of atom near a metal surface .Next ,we developed this case to the spontaneous emission of atom near two metal surfaces ,and analyzed the multi-periodic oscil-lating phenomenon appeared in the spontaneous emission rate of atom near two metal surfaces .
