摘要：
We study the nonequilibrium pressure and temperatures within the framework of extended thermodynamics of gases with 6 independent fields. We derive thermodynamic relations for these quantities from the entropy principle. These relations indicate the usefulness of nonequilibrium thermodynamic potentials. We also introduce the nonequilibrium temperatures by using the caloric equation of state, and prove that the two different definitions of nonequilibrium temperature are equivalent to each other.
