热扩散率
thermal diffusivity
rekUOSQnlU热扩散率(thermal diffusivity)物体在加热或冷却过程中，各部分温度趋向一致能力的特征参数。又称导温系数。热扩散率a是一个综合参数，a一刀Pc户，单位mZ/s，式中p为材料的体积质量，又为热导率，‘，为定压质量热容。它用来说明不稳定导热过程中温度变动速度的特征。材料的a值越高，则在同祥的外部加热或冷却条件下，材料内部温度的传播速度越大。各点的温差就越小。a是不稳定传热过程的热分析和计算的重要参数。间歇式窑炉窑墙温度分布和蓄热量计算;隧道窑的窑车蓄热量计算都需要用到耐火材料的热扩散率。热扩散率的测量采用非稳态法，常用激光脉冲法。仪器的测量原理是:在一个四周绝热的薄圆片试样的正面，辐照一束垂直于试样正面的均匀的激光脉冲，试样被单面加热，测出在一维热流条件下试样背面的温升曲线，计算求得热扩散率值。 (汪厚植)
