摘要
利用断电热线法对均匀颗粒散体的热导率进行了实验研究，以考查颗粒尺寸对热导率的影响，在以煤粉炉尾部受热面煤灰为试样的实验中得到了不同尺寸颗粒的自然堆积热导率、同尺寸颗粒不同堆积密度的热导率曲线。
By means of cutout not wire method the effects of particle size and piled density on the thermal conductivity of the coal ash with nomogeneous particles in pile was investigated.The curves of thermal conductivity at various particle sizes and pile densities are obtained.
