在ISO 9705 标准房间通过模拟实验研究了细水雾与火灾烟气的相互作用，揭示了细水雾作用下烟气中氧气、一氧化碳和二氧化碳浓度的变化规律，建立了氧气、一氧化碳和二氧化碳浓度与细水雾工作压力及风机速率的数学模型。实验发现当风机速率达到1.5 kg/s 时烟气组分浓度变化规律发生突变，对这一现象进行了深入分析和解释。本文为细水雾技术用于火灾烟气抑制提供了必要的理论基础和科学的参考依据。

Interaction between water mist and fire smoke is studied by experiments in ISO9705 room. The variational principles of oxygen, carbon dioxide and carbon monoxide concentration is disclosed and the mathematics relations of smoke component concentration with water mist pressure and ventilation speed are established according to the experimental results, it is found in the experiment that when ventilation speed exceeds 1.5kg/s the smoke component concentration breaks. This paper provides necessarily theory for water mist technology using in smoke restraining.
