摘　　要：利用Mie散射理论及其递推公式并结合舰船尾流气泡的测量结果,得到了舰船尾流中气泡群的散射相位函数。通过对散射相位函数的分析与讨论,得出:尾流存在时间及气泡群分布模型参数的变化对散射相位函数的影响较小,仅当小半径气泡密度增加时其后向散射强度略有减小;尾流气泡相对于海水的折射率变化是影响尾流气泡群散射相位函数的主要因素,相对折射率越大,后向散射越弱。Scattering phase function of bubbles in ship wake is obtained in this paper using Mie theory and its recursive formula based on wake bubbles measurements of a destroyer.By analyzing and discussing the bubble scattering phase function it turns out that： the influence of the existing time of wake and the parameter of its bubbles distributing function is weak to scattering phase function.When the density of little radius bubbles increases the backward scattering phase function minish slightly;the change of the most important factor which can affect the scattering phase function of wake bubbles.The backward scattering is weaker while the seawater refractive become lager.
