Abstract：Discuss the macroscopic properties of thermodynamics Department of commonality nonequilibrium thermodynamics of open systems interfere with each other intrinsic link between the phenomenon, which uses the concept of entropy production, to choose generalized thermodynamics "flow" and "force" to discuss a variety of mutual interference phenomenon irreversible processthe relationship between, and clarify the system in the "flow" and "force" function and phenomenological coefficients contact. During transport from the gas near equilibrium three macro law, through the establishment of non-gravitational elastic rigid sphere model, reveal the microscopic transport laws essentially statistical physics methods, and explore its linear irreversible process and far from equilibrium non-the law of motion of the balancing process, clarify the gas transport process helps the reader's understanding of the nature of its role in the irreversibility of the macroscopic process.

1 绪论

经典热力学讨论了平衡态和可逆过程。本论文研究气体内运输过程的规律也是从近平衡态着手，分析其三种运输过程的宏观规律。而非平衡态热力学任务是研究开放系统相互干扰现象中的内部联系，判断其稳定性。目的是力求增加新的理论来继承和延伸经典热力
