L ED光源发出的稳定的近似平行复色光经过多分散系微粒（水蒸气微粒）散射后形成M ie散射。分析了球形微粒散射光强的角度分布，获得了水蒸气液滴的散射色度谱，测量了水蒸气分散系的光学厚度。观察了平行光经过沸水凝结而成的水蒸气和加湿器产生的水蒸气的corona现象，并比较了彩虹和Mie散射的形成原理。

When parallel polychromatic light created by LED source passed polydispersed particles such as steam ,the Mie scattering appeared .The angle distribution of the intensity of spherical parti‐cle scattering was analyzed ,the scattering chroma spectrum of steam was obtained ,and the optical thickness was measured .The corona phenomena were observed when parallel light passed the steam created by boiling water and humidifier ,and the principle of rainbow and Mie scattering was com‐pared .
