摘要
实验测定了不同粒径珠光砂在不同真空度下的表观导热系数。采用真空粉末材料的导热—辐射复合传热模型，给出数值求解结果。提出了利用此模型将实验条件下的数据外推到其他条件下的方法。
The experimental research on the apparent conductivity of pearlite in different particle sizes and different vacuity is reported. The model of conduction and radiation heat transfer in vacuum pellet materials is used and its numerical solution is given. This paper presents a method by which the experimental result can be extrapolated to other situation.
