摘要
用稳态平板法测定了不同温度下液体的导热系数.对冷却速率的计算分别采用线性拟合、逐差法等6种方法;并计算出了相应的导热系数.最终的导热系数计算结果表明,在冷却速率的6种计算方法中,线性拟合效果比较好.
The thermal conductivity of liquid at different temperatures has been measured by using the stable plate method.Six methods such as linear fitting,progressive difference and so on,are used in the calculation of cooling rate. Meanwhile,the corresponding thermal conductivity coefficients have been calculated. The final thermal conductivity calculation results show that the result given by linear fitting among the six different ways is the best.
