讨论了最近引入的广义正则系综的一个性质[M]。李建军，李建军，李建军。广义正则系综及其与微正则系综的等价性[j].物理学报，2005,33(1):1 - 3。我们证明了该系综可用于将标准正则系综的亚稳或不稳定（非平衡）态转化为广义正则系综内的稳定（平衡）态。因此，广义正则系综内的平衡计算可以用来获得关于正则系综中非平衡态的信息。
We discuss a property of our recently introduced generalized canonical ensemble [M. Costeniuc, R.S. Ellis, H. Touchette, B. Turkington, The generalized canonical ensemble and its universal equivalence with the microcanonical ensemble, J. Stat. Phys. 119 (2005) 1283]. We show that this ensemble can be used to transform metastable or unstable (nonequilibrium) states of the standard canonical ensemble into stable (equilibrium) states within the generalized canonical ensemble. Equilibrium calculations within the generalized canonical ensemble can thus be used to obtain information about nonequilibrium states in the canonical ensemble.
