| 摘 要： | 通过实验，分析了银胶分散系物理性质对Tyndall效应的影响，发现在相同实验条件下，两种不同银胶体系中激光束呈现出明显不同的光径。在配比较小的银胶体系中，激光束呈现清晰的光锥，透射光强度明显减弱。溶胶分散系的物理性质影响其对光的散射和吸收，其中分散度影响程度相对显著。在同种分散系中，分散度和浓度较大的分散相，对光的散射和吸收作用较强；在垂直于入射方向可获得较强的散射光谱信号。

| Abstract: | The influence of physical properties of silver colloidal disperse system on Tyndall effect is analyzed, it is discovered that the laser beams in two different kinds of silver colloidal disperse system show different light paths distinctly under the same experiment condition. And the result is reached that the laser beam traveling in silver colloid of lower ratio exhibits a light cone, and the intensity of transmission light is reduced relatively. The scattering and absorption of sol disperse system for light is influenced by its physical properties, and among them dispersity is notable relatively; In the same kind disperse phase, the more dispersity and density of it, the stronger influence on scattering and absorption for light; And the stronger signal of scattering spectra can obtain in the direction perpendicular to incident ray direction. |
