Origin软件在冷却法测金属比热容实验数据处理中的应用

The Application of Origin in Experimental Data Processing for the Experiment of Metal Specific Heat Capacity by Cooling

利用Origin软件的绘图、求导、线性拟合等功能,处理冷却法测金属比热容实验中金属的冷却规律的数据。并根据肖维勒准则剔除了异常值,最终得到金属铜的冷却表达式。此方法简便快捷,结果直观准确。

With the functions of drawing,differentiating,linear fitting of the Origin software,the experimental data on the law of solid cooling,which is the part of the measurement of metal specific heat capacity by cooling,was processed.According to the Chauvenet’s Criterion,the anomalies was rejected.Finally,the cooling formula of copper had been obtained.This method is simple and rapid,and the result is intuitive and accurate.
