摘要
以处于半径为R,高为h的圆柱体中的单原子理想气体作为热力学系统,从经典统计出发,对系统作匀角速度转动时的热力学问题进行讨论,给出了该系统的描述方法、热力学关系、热力学函数及热平衡条件.结果表明,当转速小时,转动热力学系统的热力学性质与无转动时相差很小,当转速大时,转动热力学系统的热力学性质与无转动时相差较大,且热平衡条件与无转动时的条件完全相同,相平衡条件和力学平衡条件与无转动时的条件不同.
The thermodynamic problems of the system of uniform angular velocity rotation are discussed in detail and the thermodynamic system is single atom ideal gas in a cylinder of R radius and h height from classical statistics. The description method, thermodynamics relations, thermodynamics function and condition of heat balance of the system are given. The results show that when the speed hours, turning the thermodynamic properties of the thermodynamic system and no rotation difference is very small and when the speed, turning the thermodynamic properties of the thermodynamic system and no rotation is large different. The condition of thermal equilibrium is identical with the condition of non-rotating condition and the condition of phase equilibrium and the condition of mechanical equilibrium are different from the conditions of rotation.
