摘要：

We combine the definition of temperature for a Hamiltonian dynamical system with the Hamiltonian representation of a nonequilibrium isokinetic steady state to obtain an expression for the temperature away from equilibrium. Results of numerical simulations, performed to assess the validity of this approach for color field systems, are reported. A strong correlation between the kinetic temperature orthogonal to the color current and the ratio of the averages of two given phase variables is observed. [S1063-651X(99)50101-3].
