中文摘要：

运用燃烧相似分析中的辐射相似模型理论，在合理简化的前提下，推导了高原低压地区室内小型池火顶棚烟气质量浓度变化与常压地区的关系．理论分析表明，顶棚烟气质量浓度增长速率与气压的6次方成正比结合国内外研究人员不同海拔地区的池火实验结果，在海拔高度范围40～3700m内（环境气压0．066～0．1MPa）对理论关系式进行了验证，结果表明，理论预测与实际测量之间具有较好的一致性．理论分析定量反映出池火顶棚烟气质量浓度随环境气压的变化规律．

英文摘要：

According to radiation fire modeling analysis, the relationship of enclosure fire ceiling smoke concentrations under different ambient atmospheric pressures was presented. The theoretical analysis shows that ceiling smoke concentration decreases with a 6-power law of air pressure, which was proved by the experimental data of polyurethane and heptane pool fire obtained by other researchers at the ambient pressure from 0.066 to 0.1 MPa （altitude from 40 to 3 700 m）. The experimental results show that, although there is more or less imprecise factor, scaling analysis is still a good method for forecasting the relationships bewteen ceiling smoke concentration and ambient air pressure.
