摘　　要：比热容测量实验是普通物理实验中一个重要的基础性实验,常采用混合法测量,目前所用仪器产生的误差较大,导致实验结果偏离理论值较远.本文给出一种混合法测量比热容的新仪器,具有热交换快、测温准确、热损失少且可计算等特点.实践证明,用该仪器测量固体比热容可大幅提高测量精度,改善实验操作性.Specific heat capacity measurement is an important basic experiment. The hybrid method is often used to measure, but the present instrument leads to a large error of experiment result. This paper proposes a hybrid method of measuring heat capacity of the new instrument, which has quick heat exchange, temperature measurement accuracy, less heat loss as well as the characteristics can be calculated, etc. The instrument improves accuracy of determination measurement and is easy to operate.
