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.

目的探讨"浮肩"的手术适应证和预后影响因素。方法对1998-2006年期间采用保守治疗或者切开复位内固定治疗的20例"浮肩"患者进行随访,并用美国肩肘关节协会评分标准(ASES)评价其治疗效果。结果全部病例随访7月51月,平均18.7月,肩胛骨或锁骨骨折全部骨性愈合。保守治疗组肩关节功能评分结果平均为78.6分;手术组平均为88.2分。结论如果关节盂移位超过10mm?成角超过40°,应首选手术治疗。肩袖?韧带或关节囊等软组织损伤是否及时修复?肩峰骨折是否妥善固定?肩胛颈骨折是否功能复位以及后期康复治疗方式可能是影响预后的关键因素。
