【摘要】 为了解火烧迹地朽木燃烧和热解的烟密度特性,用JCY-2型建材烟密度测定仪对滇中地区13种朽木与相近尺寸的正常材进行了烟密度实验测定,根据曲线分析和计算了各样品的最大烟密度、达到最大烟密度时间、产烟起始时间、变化最快时间、总产烟量。研究表明,13种朽木烟密度等级与最大烟密度呈正相关,朽木烟密度等级小于正常材烟密度等级的有5种,朽木烟密度等级大于正常材烟密度等级的有8种。更多还原

【Abstract】 To understand the smoke density characteristics of the burning and pyrolysis of the burning wood, the smoke density of 13 decayedwood and the similar size of the normal growing wood in the central Yunnan area were measured by the JCY-2 building material smoke density tester. The maximum smoke density, the maximum smoke density time, the starting time of the smoke generation, the fastest changing time and the total smoke production amount of each sample were analyzed and calculated according to the curve. The results showed that the density of the decayedwood is positively related to the maximum smoke density.There are 5 kinds of decayed wood whose smoke density grade is lower than that of normal wood, and there are 8 kinds of decayed wood whose density grade is higher than that of normal wood.更多还原
