The influences of decay coefficient of the cavity and the intensity of the field on the phase distribution as well as its fluctuation are discussed.The results show:if there is absence of the phase damping,the phase distribution oscillates with the period π/λ.It presents single leaf at t=nπ/λ,but it splits into multi-leaf construction during the evolution period due to the interaction between the field and the atoms.

结果表明：当腔不存在损耗时，光场相位分布概率以π/λ作周期性振荡；且在t=nπ/λ时刻，光场和原子是退纠缠的，相位分布概率曲线在极坐标图中呈单叶型结构；但在演化周期内，由于光场与原子的相互作用相位分布概率曲线会劈裂为多叶型结构。
