摘　　要：通过实验和计算证明O2浓度分析是评价含添加剂细水雾灭火有效性的简单而有效方法。采用燃烧分析仪测定细水雾灭火实验过程中的O2浓度,比较含不同添加剂细水雾和纯水细水雾在同一实验控制条件下的O2浓度变化规律,利用O2浓度变化规律判断含添加剂细水雾灭火的效率。By means of the experiments and calculation, it is proved that the analysis of O2 volume percentage is the brief and valid e- valuation method of fire extinguishment capability of water mist containing additives. By O2 volume percentage, which is measured with the smoke analysis instrument, the O2 volume percentage variety regulation is obtained, and compared under the same experiment situation of fire extinguishment experiments of water mist containing additives and no additives. Fire extinguishment capability of water mist containing additives is judged by the analysis of variety regulation of O2 volume percentage.
