摘　　要：构造了SU(2)q-形变奇、偶相干态和q-形变光子数态0〉q和1〉q的相干迭加态,用数值计算的方法讨论了迭加系数、变形参数对非经典效应的影响.通过研究这种态的寻常非经典效应和q形变非经典效应,发现当q形变增大时,压缩效应均出现减小的趋势,反聚束效应和出现反聚束效应的R取值范围均增大.The superposed states,which are composed of the SU（2）＇s odd and even q-coherent states and q-deformed photon number states ｜ 0〉q and ｜ 1 〉q ,are constructed. The influences of the coefficients of superposition and deformed parameter on these nonclassical properties are discussed with the aid of numerical calculation. Then, the ordinary nonclassical properties and q-deformed nonclassical properties are studied. It is found that ,with the q-deformation increasing,the squeezing properties of the superposed states are weakened,and both antibunching properties of the superposed states and R＇s range of the existence of antibunching properties are enhanced.
