摘　　要：根据M ie散射理论研究水介质中微空气泡的光散射特性,给出了散射强度分布、散射光的偏振度与散射角的关系和前向散射光强与气泡半径的关系.研究表明,在一定波长下,前向散射光强与气泡半径呈线性关系,为空气泡的测量提供了理论模型.Based on Mie scattering theory, the laser sacttering characteristic of microbubbles in water was studied. We presented the relationship between scattering intensity and scattering angle, that between polarisation rate and scattering angle as well as the relationship between forward scattering intensity and microbubbles radius. It was found that the forward scattering intensity linearly charged with microbubbles radius at definite incident light wavelength. This work can provide the theory model for the measurement of microbubbles.
