摘　　要：引入调控奇偶相干态的权重参数R，构造了具有更广泛意义上的叠加相干态，并将其推广到q-形变情形．用数值计算方法研究了叠加相干态的非经典效应——亚泊松分布．结果表明：参数R在200附近取值时，叠加态呈现出亚泊松效应;R取其他值时，随着R的增加，Fano因子Fn增大;形变参数q的取值范围为0．1～0．9，当q参数远离1．0时，Fano因子Fn减小．The more general superposed states of even and odd q-coherent states were investigated, to which a parameter R was added. The subpoisson distribution was discussed by a numerical calculation method. The result showed that the parameters such as q and R have an influence on the superposition. When R is given in 200, the states exists the subpoisson distribution. The Fano factor increases with the increasing of the parameter R and decreases when the deformation parameter q deviates from 1.0.
