摘　　要：介绍了氮气泡沫研究进展和现状,分析了氮气泡沫的灭火原理、稳定性以及应用实例。氮气是惰性气体,不溶于水,在水中扩散速率较小,其与泡沫液混合发泡产生的氮气泡沫与空气、二氧化碳等相比,具有持久惰化、稳定性好,灭火效果显著等优势。The research and application progress of nitrogen foam was reviewed. The fire extinguishing principle,the stability and application examples of nitrogen foam were analyzed. Nitrogen is an inert gas, insoluble in water witha small difusion rate. Compared with air and carbon dioxide,the foam produced by nitrogen and foam were superior in long - term inerting,stability and fire - extinguishiing effect.
