我们研究了存在瞬态效应的情况下孤立原子和杰恩斯-卡明斯原子之间的纠缠特性。这些效应是由于原子场耦合的调制造成的，在线性扫描的情况下考虑了其显式时间依赖性。我们证明了纠缠的突然死亡可以通过瞬态效应来控制。这些作用可以及时抑制纠缠的猝死。
We investigate the properties of entanglement between an isolated atom and a Jaynes—Cummings atom in the presence of transient effects. These effects are due to the modulation of the atom-field coupling whose explicit time-dependence is considered for the case of the linear sweep. We show that the sudden death of entanglement can be controlled by the transient effects. These effects can suppress the sudden death of entanglement in time.
