摘　　要：根据顺流火蔓延理论推导了适用于ISO 9705墙角火实验的壁面材料火蔓延的热释放速率数学模型,考虑到材料厚度对热释放速率的影响,在模型推导过程中引入了一个与材料厚度相关的参数α,同时在小尺寸实验得到的材料火灾特性数据基础上,利用发展出来的热释放速率模型,对4种不同厚度胶合板的全尺寸热释放速率进行预测,并将预测结果与全尺寸实验结果进行比较.结果表明,本文建立的数学模型能够较好地预测较厚材料的热释放速率变化趋势.According to the theory of concurrent flow flame spread, a heat release rate model of wall and ceiling material fire spread was developed. The standardized bench-scale tests were used to provide input data for material properties. While ,developing the mathematical model, a new parameter depending on the material＇ s thickness was put forward. Results from calculations were compared with the full-scale experimental data, which shaws that the new mathematical model can well predict the heat release rate of thick lining materials.
