利用DISLab温度传感器测金属比热容

Study on the Experiment of Specific Heat Capacity with Metals by Temperature Sensor

针对用冷却法测金属比热容实验的不足,对实验进行了改进。利用DISLab温度传感器测量金属样品在冷却过程中,温度随时间的变化速率,以解决传统的冷却法测金属比热容实验中,用热电偶和秒表测量时产生的误差较大问题。实验表明,该实验方法与传统实验相比,不仅操作简便,而且精度高,具有明显的优势。

In allusion to the shortcoming in the metal＇s specific heat capacity test carried out by the cooling method,we have improved on the experiment. We use the DISlab temperature sensor to study the specific heat capacity of metal when they are put in the same change of temperature to avoid the inaccuracy caused by thermocouple. And draw the dynamic T-t curve to get the specific heat capacity of metal, the result is quite satisfactory.
