摘　　要：利用Fock空间的平移算符引入了双曲正弦和余弦算符,该算符作用在真空态上给出奇相干态和偶相干态的一种新表示形式,并讨论了奇、偶相干态的准概率分布函数和非经典特性.The hyperbolic sine and cosine operators are introduced by the agency of translational operator in Fock space, thier action on the vocuum state give the new expressions of odd and even coherent states. And the quasi-probability distribution function and non-classical properties of odd and even coherent states are studied.

关 键 词：双曲正弦算符 双曲余弦算符 奇相干态 偶相干态
