摘　　要：提出了一种新的衡量散射体系中散射颗粒消光能力、散射能力和吸收能力的方法并与传统方法进行了比较。在此基础上 ,讨论了散射颗粒折射率和颗粒大小对其散射能力的影响。运用此方法可以为各种散射体系 ,尤其是强散射体系选择恰当的散射颗粒 。In this paper, a new definition was proposed to better describe extinction, scattering and absorption capabilities of scatters in scattering media The influences of in refractive index and size of scatterers on scattering strength were discussed respectively It has been shown that optimal scatterer size and refractive index can be obtained in a more reasonable manner than that by the combination of Mie parameters and R factor
