Origin在不同材料导热系数测定中的应用

Application of Origin in Thermal Conductivity for Different Materials

针对导热系数测定实验中数据处理不准确的问题,对牛筋、橡胶、铝三种不同材料在自然冷却和风扇冷却条件下的导热系数进行了测量,利用Origin软件进行分析比较表明,用二项式拟合和指数拟合即可得到较高的相关度,并且材料的导热系数与降温方式无关。

Thermal conductivities have been measured for different samples of tendon,rubber and alu- minum under the conditions of natural cooling and wind cooling, respectively. And this paper focuses on how to solve the question that data processing is not accurate. Fitting, analysis and comparison of experimental data have been conducted by using OriginT. 5 software. It shows that higher correlation could be obtained by applying binomial fitting or exponential function fitting for the experimental data and thermal conductivities of different materials have nothing to do with the cooling way.
