摘要：
The group contribution method proposed by Golam Mostafa et al. and its use for the prediction of heat capacities of solid binary oxides is discussed. C-pm(298) for 113 oxides were predicted and the mean error of 4.3% and the maximum error of 26.3% were found. The proposed temperature dependencies of C-pm of the form C-pm = a + bT + c/T-2 + dT(2) show in some cases unrealistic behavior due to the negative value of the predicted constant d.
