摘要：

It is proved that almost all energy eigenstates of a certain isolated system have the following property: quantum expectation values of all local observables are equal to these statistical expectation values. Temperature is uniquely determined by energy density. (C) 2001 Elsevier Science B.V. All rights reserved.
