【摘要】In order to investigate the scattering effects of ship wake while laser transfers in bubbles ,the single scattering albedo (TSSA) of ship wake including a single bubble and bubble films is calculated by using the Mie scattering theory . Results of the investigation show that TSSA of a single bubble increases with rising radius in less than 0 .6μm ,but appears fluctuant w hile the radius becomes lager ,and finally is stabilizing ;TSSAs of ship wakes decrease with the increase of refractive index imaginary part and the real part increases ,and increases with the increase of wavelengths between 0 .4 μm and 0 .8 μm ;TSSAs of ship wakes in central region and the far field area are higher than in the near field area ,and increase with depth .%为研究激光在船舰尾流中传输时的散射效应，利用M ie散射理论对船舰尾流单次散射反照率进行了理论计算．结果表明：气泡半径小于0．6μm时单次散射反照率随半径的增大而增大，半径大于0．6μm时，单次散射反照率随气泡半径增大出现波动并且逐渐减小，直至趋于平稳；船舰尾流单次散射反照率随着折射率虚部和实部的增大而减小，波长在0．4～0．8μm之间时船舰尾流单次散射反照率随波长的增大而增大；船舰尾流单次散射反照率在中心区域和远场区域数值高于近场区域，随深度的增加而增加．
