摘　　要：采用长27cm、直径3mm不同含水率的佛香,进行了垂直向下阴燃过程实验,研究含水率对阴燃传播速度的影响规律。结果表明,佛香一般70 min内燃尽。不同含水率的佛香阴燃传播速率在初始20 min内有显著差异,含水率从绝干增加到35%(干基)时,阴燃传播速率从约0.58cm/min降到约0.25cm/min。在其后的几十分钟内,阴燃传播速率没有明显差异。红外图像分析表明,干湿佛香阴燃时高温区厚度均约为3mm。The downward smoldering experiments of Buddha incense with different moisture content was carried out to study the influence principle of moisture content on smoldering speed.The length and diameter of Buddha incense were 27 cm and 3mm.The burnout of Buddha incense was in about 70 min.The smoldering speed of Buddha incense with different moisture content was different in 20 min.The smoldering speed decreased from 0.58cm/min to 0.25cm/min with the increasing of moisture content from 0to 35%.The smoldering speed of all the Buddha incense was similar after 20 min.The thickness of high temperature area during the smoldering of dry and moisture Buddha incense was about 3 mm according to the infrared picture analysis.
