摘要
本文基于稳态“冷源”法设计了一种实现在常温环境下测量冰的导热系数的实验装置.结果表明,该系统对冰的导热系数测量准确,重复性好,操作简单,成功率高,应用前景广阔.该研究也是大学物理实验教学中“物体导热系数的测定”实验的拓展,对促进实验教学以及冰这一物质的研究具有重要意义.
In this paper,an experimental device for measuring the thermal conductivity of ice at room temperature is designed based on the steady-state“cold source”method.The results show that the thermal conductivity measurement of ice is accurate,the repeatability is good,the operation is simple,the success rate is high,and the application prospect is broad.This research is also an extension of the experiment of“determination of thermal conductivity of objects”in university physics experimental teaching,which is of great significance to promote experimental teaching and the study of ice as a substance.
