文中采用时间演化算符，考虑到初始原子相干性及失谐量，研究了单个二能级原子与压缩真空态辐射场相互作用中原子的偶极压缩。
Considering the initial atomic coherence and the detuning, dipole squeezing of a two-level atom interacting with squeezed vacuum field is studied by means of the time-evolution operator method.
结果表明：原子偶极压缩量随初始光场强度增大而增加，但压缩时间缩短。
Results show that the amount of dipole squeezing increases while the duration of dipole squeezing decreases with increasing initial field intensity.
