提出了估算二元复合氧化物比热容的双参数模型。用此模型可估算由CaO、SiO2、TiO2等44个简单氧化物之间形成的二元复合氧化物的比热容，涉及硅酸盐、铝酸盐、钛酸盐、硼酸盐、磷酸盐、碳酸盐、硝酸盐等多个复杂体系。在估算已知的300个二元复合氧化物比热容时，平均误差为379 J/(mol·K)，标准差为497 J/(mol·K)。用此双参数模型还可估算三元复合氧化物的比热容，在估算已知的28个三元复合氧化物比热容时，相对误差的平均值为39%，相对误差的标准差为43%。
The twoparameter model was established, which can estimate heat capacity of binary complex oxides including many systems such as silicate, carbonate, aluminate, borate, phosphate, sulphate, sulphite and nitrate, etc. The average error is 379 J/(mol·K), and the standard error is 497 J/(mol·K) when 300 known binary complex oxides are estimated by means of the twoparameter model. Ternary complex oxides can also be estimated by using the model. The average value of relative error is 39%, and its standard error is 43% when 28 known ternary complex oxides are estimated by means of the twoparameter model.
