摘　　要：通过推广Pegg和Barnett的相位算符和相位态到q变形的双模情况,应用数值计算研究了q变形对相干态的相位概率分布特性．结果表明,q变形对相干态的相位概率分布受到相位参数、q参数和参数|ξ|的调节,从而反映出不同的量子相干特性．Based on our previous work, the phase state and phase operator introduced by Pegg and Barnett are generalized to two-mode q-deformed circumstances. With the aid of numerical method, the phase probability distributions of q-deformed pair coherent state are investigated. It is shown that these probability distributions of the state are regulated by the parameters of phase, the q-number and the magnitude of ｜ξ｜. Therefore, the q-deformed pair coherent state exhibits different quantum interference properties.
