摘　　要：在混合法测金属比热容实验中,系统与外界的热量传递、水的热蒸发、搅拌器的搅拌动能打破了混合法量热的基本实验条件,温度和没入水中温度计体积的测量又不同程度地影响着实验的精度。本文就这些问题进行了分析和研究,并提出了相应的对策。In the experiment of Measuring metal specific heat by mixing method,The basic experiment condition of heating measuring by mixing is broken by the heat exchange between the system and the outside,heat evaporation of water and the function of the mixer. The accuracy of the experiment is affected in different degrees by the temperture and the volume of the themometer which is sunk in water. Analysis and study have been made to these problems in this essay,and ways that deal with these problems are raised.
