中文摘要：

我们在一个绝缘的平板附近处于一个原子的自发的排放率学习摆动。排放率用量 electrodynamics 作为系统尺寸的一个函数被计算。它展出多周期的摆动。摆动的四频率被 Fourier 变换提取。他们同意光子的行动靠近轨道的走开并且回到原子。当在射出的光子之间的量干扰效果的表明在原子和回来的光子附近飘动，这些摆动被解释波浪旅行沿着各种各样靠近轨道。

英文摘要：

We study the oscillations in the spontaneous emission rate of an atom near a dielectric slab. The emission rate is calculated as a function of system size using quantum electrodynamics. It exhibits multi-periodic oscillations. Four frequencies of the oscillations are extracted by Fourier transforms. They agree with actions of photon closed-orbits going away and returning to the atom. These oscillations are explained as manifestations of quantum interference effects between the emitted photon wave near the atom and the returning photon waves travelling along various closed-orbits.
