摘　　要：本文引进短时弱耦合近似研究了虚光子过程对单光子Ｊａｙｎｅｓ－Ｃｕｍｍｉｎｇｓ模型的原子压缩效应的影响，在选定初始条件下发现此影响与耦合强度，初始平均光子数，光子频率和光场位相有关。In this paper, considering the approximation of short-time and weak coupling of atom-field interaction, we have investigated the influence of virtual-photon processes on the squeezing of atom in the one-photon Jaynes-Cummings model, we found that this influence is related to the coupling strength, initial mean photon number, the optical frequency and the phase of the field.PACS number(s): 42.50.Dv
