定义了相对论非平衡定态的有效温度。传统的NESS有效温度是由涨落与耗散之比定义的。然而，一般来说，NESS相对于热浴具有相对速度，因此在相对论系统中，传统的有效温度可以是依赖于框架的。适当的有效温度被引入作为一个框架无关（洛伦兹不变量）的数量，表征NESS。我们发现，适当的有效温度的NESSs是高于适当的温度的热浴在一个广泛的全息模型，即使当传统的有效温度低于温度的热浴。
We define a proper effective temperature for relativistic nonequilibrium steady states (NESSs). A conventional effective temperature of NESSs is defined from the ratio of the fluctuation to the dissipation. However, NESSs have relative velocities to the heat bath in general, and hence the conventional effective temperature can be frame dependent in relativistic systems. The proper effective temperature is introduced as a frame-independent (Lorentz invariant) quantity that characterizes NESSs. We find that the proper effective temperature of NESSs is higher than the proper temperature of the heat bath in a wide range of holographic models even when the conventional effective temperature is lower than the temperature of the heat bath.
