The results show that the scattered radiant intensity is always symmetric with respect to the polarization plane, and that the scattered intensity is sensitive to the scattering particle size regardless of the incident radiation polarization, and finally, that the vertical components in the scattered light are totally different distribution for two kinds of polarized radiation.

散射粒子直径分别为：1.24μm、0.494μm、0.36μm、0.123μm、0.065μm。以粒子与水技不同比例混合液，作为散射粒子场。所得结果表明，散射光强度总是相对入射光束的偏振面呈对称分布；散射光强度对散射粒子大小敏感而与入射光偏振态无关；散射光中垂直偏振分量在两种光入射下存在完全不同的状态分布。

The antimony doped tin oxide nanoparticles were synthesized at 240℃for 17 h by the complexing hydrothermal oxidation method using stannate, antimony white and sulphuric acid as the starting materials, sodium hydrotartrate as the complexing agent and hydrogen peroxide as the oxidant. The resulting powders were characterized by means of differential thermal analysis, infrared spectrometry, X-ray diffraction and transmission electron microscope. The mechanism of the preparation of ATO powder was investigated as well.
