内能判据的应用与讨论

The Application and Discusses About Internal Energy Criterion

由内能判据推导出了均匀系统的平衡条件和平衡的稳定性条件,并由内能函数推求出了存在热传导(系统内外)和物质输运时,不可逆过程中内能流密度与局域内能减少率的表达式。这为用上以外的其它热力学函数研究不可逆过程进行的速率问题提供了有益的参考。

The equilibrium condition and the balance stable condition of homogeneous system are inferred with the internal energy criterion, and this paper inquires into internal energy current density and confined internal energy decrement expression in irreversible process. The ratio expression of internal flow density to heat conduction （system inside and outside） and material transportation with internal energy function. This research provides useful references for using other thermodynamic functions to study the rate of irreversible procedure.
