考虑腔场处于弱相干态的情况，研究了两个全同的二能级原子与耦合腔相互作用系统中原子的偶极压缩和原子间的纠缠特性。研究结果表明，随耦合腔耦合系数增大，原子的偶极压缩减弱。另一方面，随耦合腔耦合系数增大，原子间的纠缠也减弱，这一结果与耦合腔处于真空态的情况相反。

Quantum properties of the system comprising two two-level atoms and resonant interaction with two coupled cavities which are in weak coherent states initially are studied. The atomic dipole squeezing is investigated. The results obtained using the numerical method show that atomic dipole squeezing is weakened with the increase of the coupling constant of the coupled cavities. On the other hand, atom-atom entanglement is also weakened with the increase of the coupling constant of the coupled covities, and this result is contrary to that of the case that the coupled cavities are in vacuum state initially.
