摘要
详细计算了αｋ（ｋ≥３）的ｋ个正交归一本征态的相位和粒子数起伏以及粒子数一相位不确定关系，讨论了相位和粒子数起伏的特性以及产生粒子数一相位最小不确定关系的条件，并同压缩真空态进行了比较．
The fluctuations of phase, number and number-phase uncertainty relations in the k orthonormalized eigenstates of the operatorαk(k≥3) are calculated in detail. The properties of the fluctuations of phase and number and the condition of producing number-phase minimum uncertainty relations are discussed, at the same time, some characteristics of the einenstates of at are compared with that of the squeezed vacuum saute.
