本文提出了一种计算火灾中有烟层空间内目标亮度、疏散人员视野内亮度分布和标志可见度的模型。首先，研究了烟雾对暴露于烟雾中的目标的粘附性，以此为基础建立了预测火灾烟雾中目标亮度的模型。利用真实的烟雾房间进行了光度测量实验，验证了该模型的有效性。最后，该模型被应用到预测的亮度分布在疏散人员的看法和实例结果表明，假设一个普通的办公空间的情况下。
This paper presents a model for calculating target luminance, luminance distributions in evacuees’ view and visibility of signs in a space with a smoke layer in fire. First, a smoke adhesion to a target exposed to smoke is investigated as a basis to establish a model for predicting target luminance in fire smoke. The model is validated by conducting a photometrical experiment using real-scale room filled with smoke. Finally, the model is applied to the prediction of the luminance distributions in evacuee's view and example results are demonstrated for a case assuming an ordinary office space.
