| 摘 要： | 根据自然对流换热理论,利用Matlab软件计算了待测样品侧面散热损失,对非良导体热导率的计算公式进行了修正；并且利用Matlab软件合理拟合了散热盘的冷却速率.结果表明这两个方面的修正提高了实验数据处理的准确度,得到了更加准确的非良导体的热导率.

| Abstract: | According to the theory of natural convection heat transfer, the sample＇s heat radiation of side is calculated by using Matlab software, and then the formula of the thermal conductivity of poor conductor is modified. Furthermore, a good curve fitting of cooling plate＇s cooling rate is made. The results show that these two amendments can improve the accuracy of the experiment and more accurate thermal conductivity of poor conductor has been got. |
