摘　　要：基于固体比热容实验的传统实验,利用温度传感器对实验进行了改进,对混合温度进行了全程监控,取得了较好的实验效果并降低实验技术难度,清晰地观察到热力学现象,运用软件对数据图像进行线性拟合处理,提高了实验的准确性.Traditional experiment of solid specific heat capacity was improved by using tempera-ture sensor. The temperature during the mixing processes was monitored, some good experimental results were obtained. Thermodynamic phenomenon could be observed obviously and the technical difficulty could be reduced greatly. Using software for data processing, the accuracy of the measured value was also increased.
