摘　　要：为解决传统方法检测雪茄烟燃烧锥温度分布不精确、耗时长、样品消耗多等问题,建立了一种雪茄烟燃烧锥温度分布的快速检测方法。结果表明:①单次实验获得的单支雪茄烟燃烧锥温度分布和特征参数之间的差异较大,而用多次实验的平均温度数据表征雪茄烟燃烧锥温度分布和特征参数更加合适。②相较于传统检测方法,快速检测方法得到的温度分布更精细,可覆盖整个雪茄烟燃烧锥,而且燃烧状态与雪茄烟燃烧锥CT图的吻合度较好。③在0~2 s抽吸阶段,燃烧锥体积V0(区域温度≥200℃的体积)减小;体积平均温度T_(m)和最高温度T_(max)持续升高;高温区(>600℃)的体积快速增大;低温区(200~400℃)和中温区(400~600℃)的体积减小。在2~40 s静燃阶段,燃烧锥体积V0先减小到谷值,然后迅速回升到峰值后又开始减小;低温区的体积先减小到谷值后再开始增大;T_(m)、T_(max)、高温区和中温区的体积均在抽吸结束后先增大到峰值后再持续减小。④在0~2 s抽吸阶段,燃烧锥低温区和中温区的区域形态基本不变,高温区逐渐向外围扩张,由类似五边形逐渐扩张为类似等腰梯形,雪茄烟的燃烧状态逐渐达到最佳。与传统检测方法相比,快速检测方法可以同时采集单支雪茄烟径向8个深度的温度数据,对数据进行平移重构、插值处理和数理统计后,即可表征雪茄烟燃烧锥温度分布,获得与燃烧锥温度相关的特征参数,准确快捷。To accurately,quickly and effectively detect the temperature distribution in the combustion cone of a cigar,a rapid detection method was developed.The results showed that:1)There was significant variability in the temperature distribution and characteristic parameters inside cigar’s combustion cone obtained from a single experiment.However,the average temperature data from multiple experiments was more suitable for characterizing the temperature distribution and characteristic parameters of the cigar combustion cone.2)Compared with the traditional detection method,the temperature distribution obtained by the rapid detection method was more refined and could cover the whole combustion cone,and the combustion state was better matched with the CT image of the combustion cone.3)At the 0-2 s puffing stage,the volume of the combustion cone V0(the volume with a temperature≥200℃)decreased,the volume-averaged temperature T_(m) and the maximum temperature T_(max) continuously increased,the volume of the high-temperature region(>600℃)rapidly expanded;and the volumes of the low-temperature region(200-400℃)and the medium-temperature region(400-600℃)decreased.At the 2-40 s post-puffing smoldering stage,the volume of the combustion cone V0 first decreased to a minimum value,then quickly reached a peak value and then began to decrease again.The volume of the low-temperature region first decreased to a minimum value and then increased.T_(m),T_(max),and the volumes of the high-temperature and medium-temperature regions all increased to peak values after puffing and then decreased continuously.4)During the 0-2 s puffing stage,the shapes of the low-temperature and medium-temperature regions of the combustion cone were basically unchanged,while the high-temperature region gradually expanded outward from a pentagon-like shape to an isosceles trapezoid-like shape,and the combustion state of the cigar gradually reached its optimal state.Compared with the traditional detection method,the rapid detection method is accurate and
