摘　　要：设计了一种单水浴法量热实验装置,提出了对量热装置参数及待测材料的定压比热容、固—液相变焓进行标定及测量的计算方程和实验方法.通过实验对量热装置的热容、搅拌功和散热量进行了标定,对铜和水在不同温度下的定压比热容,以及冰的固—液相变焓进行了测量.结果表明,所设计的量热计及测试方法可在常温范围内精确测量材料的热物理性质.此研究可以为新型相变储能材料的定压比热容、固—液相变焓提供快速而精确的测量方法.An adiabatic water bath calorimeter was designed to measure the specific capacity and fusion heat of a material. Models and experimental method were provided to calibrate parameters and accuracy of the device, The heat capacity, stirring power and heat loss of the calorimeter were calibrated by experiments. The specific capacities of copper and water at three temperature, and the fusion heat of ice were detected by the calorimeter. It was confirmed that the results had satisfying accuracy. The calorimeter can provide accurate experimental results for the measuring of thermal properties of thermal storage materials.
