摘　　要：通过对固体比热容构成的分析,导出了固体材料比热容随温度变化的一般关系式,以Mo、α-Al2O3、graphite、W、Si3N4、SiC等六种材料为例,检验了理论模型的可行性,结果表明,其计算数据和标准数据的相对偏差均在±2%以内,证实了该模型的实用性。Based on the analysis of specific heat capacity of different solid materials,the relationship between specific heat capacity of solid materials and temperature is studied and the model is built.As the example of Mo,α-Al2O3,graphite,W,Si3N4 and SiC,the model on specific heat capacity with temperature has been verified.The results indicate that the relative deviation between calculated and standard data is not exceeding 2%.
