摘　　要：The heat capacities of KHSO4 crystal (A. R. ) have been measured with a small sample precision automated adiabatic calorimeter over the temperature range from 78 to 373 K. The experimental results have shown that there is no phase transition or thermal anomaly in this temperature region for the present crystal. The experimental heat-capacity data have been fitted to a smoothed curve with the aid of the least square method. In addition, the process of the thermal decomposition has been studied by TG analysis.The heat capacities of KHSO4 crystal (A.
