摘要
在理想量子气体和相对论概念的基础上 ,根据相对论的态密度和量子统计的粒子数密度、能量密度的结论 ,通过严格的理论推导 ,得出理想量子气体在高温条件下的相对论性的状态方程、热容量以及等压、等容、等温三种过程的熵变 ;并将经典理想气体、非相对论理想量子气体、相对论理想量子气体在高温条件下的熵变相比较 ,指出非相对论理想量子气体与经典理想气体的差异在于描述微观体系的波涵数的对称性 ,相对论理想量子气体与非相对论理想量子气体的差异在于相应的态密度的不同 ;
On the basis of the concept of perfect quantum gas and that of the relativity,and also according to the conclusions of the state density of the relativity,the densities of quantum statistics particle numbers and the densities of energy,the relative state equation,heat capacity and the entropy variation of the isobaric process,isochoric process and isothermal process of the perfect quantum gas under high temperature are obtained. Then a comparison is made among entropy variations of the classical perfect gas,non relative perfect quantum gas and the relative perfect quantum gas under high temperature and the difference between non relative perfect quantum gas and the classical perfect quantum gas is found to exist in the description of the symmetry of wave function of the microsystem, and the difference between the relative perfect quantum gas and non relative perfect quantum gas is found to lie in the difference of the related state density.Finally the author clarifies the superiority of entropy variation of the relative perfect quantum gas under high temperature in the field of quantum statistics and the practical prospect of the entropy variation in electron gas under high temperature in nuclear fussion.
