摘要：

A high-sensitivity sensor has been used with a Mettler TA 2000 B apparatus to determine precisely heat capacities in the range 170-370 K. The heat capacity of samples of aluminium oxide, aluminium and benzoic acid have been measured to test the accuracy of the apparatus and the method employed. The accuracy of the heat capacity measurements was approximately 1% over most of the temperature range and generally within 2% at the lowest temperatures.
