摘　　要：说明了硼粒子在热空气中的点火现象。阐述了两种不同的硼粒子点火机理和实验依据及相应的化学反应 ,比较了不同点火机理下硼粒子氧化层的产生和消耗速率 ,分析了影响硼粒子点火的因素 ,建立了硼粒子在空气中点火的数学模型。The phenomenon of boron particle ignition in hot air was defined. Two different boron particle ignition mechanisms and supporting experiments with corresponding chemical reactions were explained. The velocity of oxide generation and consumption in different ignition mechanisms was compared, and factors that affected boron particle ignition were analyzed. Boron particle ignition mathematical models were established finally.
