摘要: 导热系数是节能材料表征其低导热性能的重要参数，准确对其测量显得极其重要。而导热系数又随着节能材料的成分、结构、相态等的变化而变化，其测量精度是节能材料发展的基础。本文利用瞬态热带法测量装置和瞬态平面热源法测量装置对12种节能材料的导热系数进行了测量和分析，同时分析了各因素对瞬态法测量结果的影响，对比研究了多种导热系数瞬态测量方法，验证了瞬态法适用于节能材料的导热系数测量。
Abstract: The thermal conductivity is an important parameter that characterizes the low thermal conduc-tivity of energy-saving materials, and it is extremely important to measure it accurately. And the thermal conductivity with the energy-saving materials, composition, structure, phase and other changes, the measurement accuracy is the basis for the development of energy-saving materials. In this paper, the thermal conductivity of 12 kinds of energy-saving materials was measured and analyzed by means of transient tropical measurement device and transient plane heat source method. At the same time, the influence of each factor on the measurement results was analyzed. The method of transient measurement is used to verify the thermal conductivity of energy-saving materials.
