摘要
通过相似模型的方法,对隧道内不同烟雾浓度的环境进行模拟,并对光源的透过特性进行测定.通过拟合曲线与朗伯-比尔定律曲线的对比,得到不同烟雾浓度、不同色温的室内模拟实验曲线,验证了掺墨水体与烟雾胶体对光的衰减作用相似,可为考虑隧道烟雾环境下的照明设计提供室内实验参考.
This experiment aims to simulate the environment with different concentration of smoke in the tunnel and measure the transparency of illuminants with different color temperature by using similarity model. By drawing fitting lines of different smoke con- centration and different color temperature and comparing them with Lambert-beer Law, the similarity of weakening light between smoke colloid and the glue colloid can be proved,which is capable to provide indoor references of illumination design considering the smoke environment in tunnels.
