摘　　要：首先运用能量均分定理推出经典固体的热容量,然后分别从爱因斯坦模型和德拜模型出发,对经典固体的热容量进行修正,并就两个模型的特点和不足进行分析.通过研究发现金属固体的热容量在高温时可以不考虑电子气的影响,而低温时则需要考虑电子气对金属固体热容量的贡献.In this paper,we has launched solid heat capacity further from the two models is Einstein model and Debye model of computational solid heat capacity,and analyzes the characteristics and disadvantages of the two models,through the study found that in the solid metal high temperature heat capacity can not taking into account the effect of the electron gas,low temperature need to consider the contribution of electron gas of metal solid heat capacity.
