研究了两个三能级原子与独立库相互作用的纠缠动力学。研究结果表明：两个三能级原子的束缚纠缠在演化过程中转移到相互作用库中。由于整个系统纠缠信息总量守恒，原子系统束缚纠缠的猝死必然导致相互作用库中束缚纠缠的复活，库中获得的纠缠等于初始的原子纠缠。

The entanglement dynamics of two-qutrits interacted with its independent reservoirs are investigated. The results show that bound entanglement of the two-qutrits transfers to the interaction reservoirs in the evolution process. Due to the conservation of total entanglement information in the whole systems, bound entanglement sudden death of the atoms must lead to bound entanglement sudden birth of the reservoirs, and the obtained entanglement of the reservoir equals the initial one.
