摘　　要：从能量守恒方程出发，推导自由空间木垛火蔓延速率及质量燃烧速率方程，进一步得到木垛中热流密度的表达式．从而只需测得火焰温度就能通过模型求得木垛火蔓延速率及质量燃烧速率，并通过实验证明模型预测结果基本与实验结果相符．Models are given out to calculate the fire spread rate and the mass loss rate of the crib fires by using the energy conservation equation. The equation of heat flux is also given out such that the fire spread rate and the mass loss rate can be calculated by measuring the flame temperature. The results of the models are consistent with the experiments.
