摘　　要：介绍临界辐射通量的测量方法及原理。利用锥形量热仪测得试样的点燃时间和所受初始热辐射强度,拟合出两者存在的一次函数关系。对铺地材料临界辐射通量进行近似计算,利用锥形量热仪进行试验验证,给出误差分析。Measure method of critical heat flux and its principle were introduced.The ignition time and the original heat flux were tested by the cone calorimeter,and the function of first degree between them was fitted.The critical heat flux of flooring material was calculated by the equation and also tested by cone calorimeter,and the error analysis was carried out.

关 键 词：铺地材料 临界辐射通量 热辐射 热释放速率
