摘要翻译：
在远离平衡的非平衡态(NESS)中，已知爱因斯坦关系被违反。然后，扩散系数与迁移率的比值称为有效温度，并在许多工作中研究了该有效温度的物理相关性。虽然物理上的相关性还不完全清楚，但人们已经发现，有效温度在NESS中的作用在许多方面确实类似于平衡系统中的温度。在本文中，我们找到了进一步的证据来证实这一类比。利用非平衡朗之万系统作为哈密顿系统的恒温器，发现该哈密顿系统的动力学温度等于恒温器的有效温度。

英文摘要：
In non-equilibrium steady states (NESS) far from equilibrium, it is known that the Einstein relation is violated. Then, the ratio of the diffusion coefficient to the mobility is called an effective temperature, and the physical relevance of this effective temperature has been studied in several works. Although the physical relevance is not yet completely clear, it has been found that the role of an effective temperature in NESS is indeed analogous to that of the temperature in equilibrium systems in a number of respects. In this paper, we find further evidence establishing this analogy. We employ a non-equilibrium Langevin system as a thermostat for a Hamiltonian system and find that the kinetic temperature of this Hamiltonian system is equal to the effective temperature of the thermostat.
