摘　　要：构造了非简谐振子广义相干态的叠加态,讨论了该量子态的高阶压缩效应及其压缩效应随时间的变化.结果表明,非简谐振子广义相干态的叠加态,当叠加相位φ满足一定条件时出现奇数阶压缩,并给出了压缩条件与叠加相位φ的关系,其高阶压缩周期随阶数增大而减小,压缩持续时间也随阶数增大而减小并与叠加相位φ有关.The superposition of eigenstates of a non-harmonic oscillator is constructed.Its higher-order squeezing has been studied.The results show that it exhibits odd-order squeezing effects,Its squeezing period and squeezing continued time decrease when the number of order increases,and its squeezing continued time is influenced by superposition phase φ.
