本文对实际气体(范氏气体)和理想气体的热容量进行了讨论,从理论推导、微元、宏观三个方面对热容量的取值进行了详细的讨论.最后清晰地得到了热容量的取值范围及其变化规律,热容量在任意准静态过程中可取-∞到+∞间任意实数.
In this paper ,the actual gas (Van der Waals gas) and heat capacity of ideal gas are discussed ,from the theoretical derivation ,the micro and macro three aspects of the discussion of the heat capacity values in detail , finally clear to get the value range of heat capacity and its change rule ,the heat capacity can get any num bers between - ∞ and + ∞ in quasi static process .
