摘要翻译:
正确地代表统计系统的代表性统计集合的概念是严格制定的。这一概念允许对统计系统进行适当的描述,避免理论上的不一致。作为例证,我们考虑了一个玻色凝聚系统。结果表明,用一个有代表性的系综对后者进行自洽处理,总能得到守恒的无间隙理论。

英文摘要:
The notion of representative statistical ensembles, correctly representing statistical systems, is strictly formulated. This notion allows for a proper description of statistical systems, avoiding inconsistencies in theory. As an illustration, a Bose-condensed system is considered. It is shown that a self-consistent treatment of the latter, using a representative ensemble, always yields a conserving and gapless theory.
