| 摘 要： | 为了研究防火树种树叶试样的热解过程，并且评价其燃烧特性，文章采用TG（Thermogravimetry）技术在空气气氛下对13种树种的树叶试样进行了实验研究，分析了其热解特征参数，并使用应用因子分析法对热解参数进行了统计分析。结果表明因子分析法用于评价防火树种的燃烧性具有较高的可靠性，燃烧性最好的树叶是交让木叶和茶叶叶，燃烧性最差的是火力楠叶、栗树叶和木荷叶。

| Abstract: | Thirteen foliage species generally used for fuel break were subject to Thermogravimetric analysis(TGA) in air,in order to study their thermal degradation process and assess their combustibility.The values of pyrolytic parameters were analyzed in details.The combustibility of foliage species were analyzed by the methods of factor analysis.Results showed that factor analysis can be used to evaluate the combustibility of foliage species.For all the foliage species in this work,the Macropodous Tigernanmu and tea hold the highest combustibility,and the schima superb,chestnut and Michelia macclurei hold the lowest combustibility. |
