1引言从上世纪60年代开始,地毯在火灾中的作用就引起了消防研究人员兴趣,许多用来评定火灾中地毯燃烧性的实验方法也得到了发展。这些实验方法一般都涉及了地毯的引燃和火焰传播。其中一个非常重要而且具有实用价值的内容是,纵火引燃地毯上的液体燃料。在这种特殊情况下,地毯的 1 Introduction Since 1960’s, the role of carpet in fire has aroused the interest of researchers in fire protection. Many experimental methods for assessing the flammability of a carpet in fire have also been developed. These experimental methods generally involve the ignition of the carpet and flame propagation. One of the most important and practical aspects is that arson ignites the liquid fuel on the carpet. In this special case, the carpet
