【摘要】 在森林防火戒严期内,用自行设计的燃烧试验装置对落叶树种南烛(Lyonia ovalifolia)的活枝条进行了8次燃烧试验,在测定和分析样品引燃时间、试验过程中烟气温度变化和质量损失过程等基础上,提出了燃烧特征参数,即单位质量可燃物在试验过程中相对于无样品的对照试验的烟气净积温与引燃时间之比,根据该参数计算了8次燃烧试验的特征参数。研究结果表明,南烛的燃烧性在森林防火戒严期内呈动态变化,并呈逐渐下降趋势。更多还原

【Abstract】 Eight combustion experimentations on living branches and leaves of bush plant Lyonia ovalifolia were carried out during the prohibitive period of forest fire with an experimental equipment designed by the authors.The combustion characteristic parameters,namely the ratio between net accumulated temperature per unit mass fuel during sample experimental period contrast comparison experiment without sample and ignition time,were put forward based on,igniting time,smoke temperature and weight losing of sample during experimental period.The dynamic parameters of the 8 experimentations were accounted according to the combustion characteristic parameters.The results showed that combustibility of Lyonia ovalifolia changed dynamically and descended gradually during the prohibitive period of forest fire.更多还原
