摘要：

The low-temperature heat capacities from 5 to 350 K by adiabatic calorimetry and the high-temperature enthalpy increments from 470 to 877 K by drop calorimetry of BaO and SrO have been measured. From the results smoothed thermochemical and thermophysical functions have been calculated at selected temperatures up to 1000 K. For the standard entropies of BaO and SrO at 298.15 K the values (70.01 +/- 0. 10) and (53.63 +/- 0.10) J mol-1 K-1, respectively, have been found.
