中文摘要：
为研究热塑性材料下端与底板间距对其熔融燃烧行为的影响，选择6mm厚和4mm厚PP板材作为研究对象，在ISO 9705燃烧室内进行了12组大尺寸燃烧实验，分别考虑了0cm、5cm、10cm、15cm、25cm和35cm不同间距的工况．实验过程中测量了热释放速率、消光系数、CO体积分数以及温度场等火灾动力学参数．实验结果表明，热塑性材料的下边缘与底板的间距对火灾增长速率影响很大，但是对热释放速率峰值的影响不明显；随着间距的增加，壁面火和油池火之间的相互影响作用逐渐减弱，且当间距增加至15cm以上时，各组实验的燃烧过程没有明显的区别．
英文摘要：
The effect of spacing between low edge of sample and floor on combustion behavior of thermoplastics is investigated. Large-scale experiments on polypropylene sheets with thicknesses of 6 mm and 4 mm are carried out in ISO 9705 fire test room with different spacing as follows ： 0 cm, 5 cm, 10 cm, 15 cm, 25 cm and 35 cm. Fire dy- namics parameters, such as heat release rate, extinction coefficient, CO concentration and temperature field, are measured. The experimental results show that the spacing between low edge and floor has a great effect on fire growth rate but little on peak HRR value. As spacing increases, the interaction between wall fire and pool fire becomes weak. There are no distinct differences when the spacing is above 15 cm.
