| 摘 要： | 压缩真空激发态是一种具有丰富的非经典性质的态。这种态可由压缩空光场与激发原子间的多光子作用产生，为进一步研究压缩真空激发态的相位性质，本严格计算了这种态中Ｓｕｓｓｋｉｎｄ相位算符期待值，并分别讨论了压缩参数ｒ较小和较大时粒子数－相位不确定关系。

| Abstract: | The states generated by excitations on a squeezed vacuum state are a kind of states which are characteristic of possessing various nonclassical properties.Such states can be produced by the multiphoton interaction between the excited atoms and the field in squeezed vacuum state.To study the phase properties of such states,the expectation values of the Susskind phase operators in these states are calculated exactly and the number-phase uncertainty relations in the limits of small r and large r are examined respectively. |
