中文摘要：
研究了在非惯性系中相位阻尼通道下初始纠缠对纠缠演化的影响．结果发现：与振幅阻尼通道情况不同，当态参数不同而初始纠缠相同时，纠缠演化曲线重合．当Unruh单粒子态包含左右成分时，比只包含右成分时量子消相干现象更加严重，较早地出现了纠缠死亡现象，并且纠缠死亡时刻与初始纠缠无关．
英文摘要：
The influence of initial entanglement on entanglement evolution Compared with the scenario of amplitude damping channel, when under phase damping channel in noninerUal Irame IS lnvesugatea. the state parameter a has different values with the same intial entanglement, the evolution curves are identical. When the Unruh single particle state has right and left components, there is more serious quantum decoherence than the case where the Unruh single particle state has only right component with the sudden death of entanglement taking place early, and the time of sudden death of entanglement is independent of initial entanglement.
