| 摘 要： | 研究大麻秆芯粉随着外界环境温度的变化,自动地调节本身的吸温和散温速率的性质,并分别考察环境温度、温差、大麻秆芯纤维粉的堆积密度和粒度等对秆芯粉的吸温速率和散温速率的影响.结果表明,吸温和散温速率随着大麻秆芯粉粒度的减小、环境温度和温差的升高而变快.在待测物质本身温度小于35℃时,同等粒度下的大麻秆芯粉较普通木粉吸得快;在大于35℃之后,同等粒度下大麻秆芯粉较普通木粉散得快.通过对400目大麻秆芯粉在环境温度为37℃(吸温)和19℃(散温)的吸温和散温速率随温差变化的曲线,以及在环境温度为2℃(散温)和37℃(吸温)的散温和吸温速率随温差变化的曲线研究,可知大麻秆芯粉具有冬暖夏凉的功效.
