摘要
导热系数是反映材料导热性能的物理量。导热系数的测量方法有稳态法和动态法两类,采用稳态法测量不良导体导热系数,通过实验来加深学生对热传导规律的理解,掌握稳态法测量导热系数的基本方法。
Thermal conductivity coefficient is a physical quantity reflecting thermal properties of materials. Thermal conductivity coefficient measurement is composed of steady -state method and dynamic method, of which the former is adopted in this study to measure the thermal conductivity of poor conductor. With experiment, the paper aims to strengthen the understanding of the law of heat conduction and ensure the mastering of measuring thermal conductivity with steady - state measurement method.
