3种材料绝热性能的实验研究——基于导热系数测定实验

摘要

基于大学物理实验中＂导热系数测定＂的实验原理及方法,采用几何尺寸完全相同的报纸套、泡沫套、陶瓷套包裹待测铝圆柱,测定其导热系数.通过3种情形下导热系数测定值和真值的对比,从而得出3种材料的绝热性能的优劣.%Based on the experimental principle and method of ＂determination of thermal conductivity＂ in university physics experiment,thermal conductivity of aluminum cylinder is measured using papers sets,bubble sets,ceramic sets with the same geometry size to wrap it.By comparing the measured value with the true value of thermal conductivity of aluminum in three cases,the adiabatic properties of three materials are obtained.
