摘　　要：光力系统在一定参数条件下存在量子纠缠。无论单稳还是双稳机制,最大光力纠缠都没有出现在腔内光子数最多的情况下。具体地说,在单稳情况下,出现在连续光力谱线的中间一点,而双稳机制下,由于连续性被破坏,出现在下支的端点。同时,本文还系统地研究了光力模型的稳定性。Quantum entanglement usually occurs within a certain parameter range. The maximal opto-mechanical entanglement doesn＇t arise in the case of the maximal number of cavity photons no matter in monostable regime or bistable regime. Specifically,it occurs at some point in the continuous opto-mechanical spectrum in monostable regime,while it occurs at the end of a stable branch in bistable regime because the continuity is broken. Simultaneously,the stability of the opto-mechanical model is investigated systematically.
