中文摘要：

实验研究了含水率对泥炭阴燃蔓延速率的影响.通过测量燃料内部温度,分析了含水率对阴燃峰值温度、峰值温度处蔓延速率、水分蒸发前锋（T=90,℃）蔓延速率、泥炭热解前锋（T=312℃）蔓延速率和炭氧化前锋（T=421℃）蔓延速率的影响.结果表明：含水率对阴燃峰值温度影响不大,而在低含水率下各温度前锋阴燃速率随着深度的增加而减小,在高含水率下各温度前锋阴燃速率先增加后减小.同时,随着含水率增加,阴燃速率减小,含水率为100.02%,时泥炭不能发生阴燃.

英文摘要：

This work experimentally investigated the influence of moisture content on the spreading rate of naturaldownward smoldering of peat.By measuring the inside temperature profiles of the smoldering peat,the influence ofmoisture content on the peak temperature inside peat samples,the spreading rate of front where the peak temperaturewas reached,the spreading rates of moisture evaporation front at 90,℃,the peat pyrolysis front at 312,℃ and charoxidation front at 421,℃ was analyzed.The results show that moisture content had little influence on peak temperatures;the spreading rate of all the fronts decreased with the depth increase for samples with lower moisture contents,while it increased first and then decreased for samples with higher moisture contents.Meanwhile,the spreading ratedecreased with the increase of moisture content.The smoldering combustion was not sustained for samples with themoisture content of 100.02 %,.
