摘要:

为了比较藤本植物的燃烧性,利用自行设计的燃烧实验装置对昆明地区9种藤本植物的叶片进行了燃烧试验,测定了9种叶片的含水率和2种可燃叶片单位面积质量、燃烧速率和损毁速率等指标。结果表明:9种叶片中,常春藤(Hedera nepalensis var.sinensis)和常春油麻藤(Mucuna sempervirens)在纯氧环境中能被点燃,属于易燃类藤本植物,且随着含水率增加,燃烧速率和损毁程度均呈现下降趋势;叶片单位面积质量越大,其燃烧速率就越低,损毁程度越小;其它7种藤本叶片均不能被点燃,属于难燃类藤本植物。

关键词: 藤本植物, 燃烧性, 燃烧速率, 损毁程度

Abstract:

In order to compare the combustibility of lianas,the combustion experiment of 9 liana species in Kunming were conducted by means of a self-designed combustion experiment apparatus.The moisture content of 9 kinds of blades and the mass per unit area,burning rate and damage degree of 2 kinds of combustible blades were measured.The research showed that Hedera nepalensis var.sinensis and Mucuna sempervirens can be ignited in pure oxygen environment,which belonged to the class of flammable lianas.With the increase of water content,both the burning rate and damage degree showed a downward trend.The greater the mass per unit area of leaf,the lower the burning rate,the smaller degree of damage.The leaves of other 7 species of lianas can not be ignited,and belong to nonflammable lianas.

Key words: liana, combustion, burning rate, damage degree
