摘要
报道了用正规状况法快速测定颗粒状材料的导温系数α和导热系数λ的测试技术，具体叙述了测试原理。实验测定的α和λ值与文献值较为接近，实验值的重复性好。
With the aid of the theory of unsteady heat conduction, for measurement of the thermal diffusivitiys,α,and thermal conductivity,λ,of particulate solids is reported. Calculation equations have been given for αand λ.The experimental results are in agreement with published data.
