摘　　要：　研制了混合法测固体比热容的仪器. 该仪器将加热部分与测温部分巧妙的合为一体,并设计了将物体从高温快速过渡到低温的装置,从而减小了热损失,同时温度测量采用了AD590温度传感器的装置,进一步减小了实验中的系统误差.A developed apparatus to measure the specific heat capacity of solids by the mixing method is introduced, which integrates the part of heating with the part of measuring temperature. A device, which can cool the object very fast, is designed, thus the heat loss is reduced. The AD590 temperature sensor being used, the systematic error is further decreased.
