摘　　要：介绍了平移激发奇、偶相干态的非经典性质,计算了它们的准几率分布函数:P函数,Q函数和Wigner函数,并以平移激发偶相干态为例讨论了后两个函数在m与β取不同值时的变化.We introduce the nonclassical characteristics of displaced excited even and odd coherent states, calculate their quasiprobability distribution functions including Glauber-Sudarshan P function, Metha Q function, Wigner function, and study the different characteristics of these function with different m and β according displaced excited even coherent states.

关 键 词：平移激发奇偶相干态 非经典效应 准几率分布函数 量子光学
