摘　　要：利用Pegg定义的位相研究相干态及弱压缩真空态的位相特性．利用位相态分析光学放大器（或衰减器）的位相演化，并将位相几率分布的扩散与传统的Fokker－Planck结果进行比较。In this paper,the phase property of coherent state and weakly squeezed vac uum state are studied using the definition of the phase by Pegg. The phase states are used to analyze phase evolution in optical amplifers or attenuaters. The resulting diffusion of the phase probability distribution is compared with that obtained in conventional Fokker Planck treatments
