最大熵原理与非平衡统计算子方法中的源形式

Maximum entropy principle and the form of source in non-equilibrium statistical operator method

V. V. Ryazanov

摘要:

假设非平衡统计算子方法(Zubarev方法)中的指数乘子可以看作是系统过去寿命的分布密度,可以用任意分布函数代替。为了指定该分布,使用如[Schönfeldt J-H,Jiminez N,Plastino A R,Plastino A,Casas M 2007 \textit{Physica A} \textbf{374} 573]中的最大熵原理的方法。所得分布接近指数分布。最大熵原理的另一种方法,如在[Van der Straeten E and Beck C 2008 Phys. Rev. E \textbf{78} 051101]中,除了指数分布产生类似幂的对数正态分布,以及其他类型的分布和它们之间的过渡。

英文摘要:

It is supposed that the exponential multiplier in the method of the non-equilibrium statistical operator (Zubarev`s approach) can be considered as a distribution density of the past lifetime of the system, and can be replaced by an arbitrary distribution function. To specify this distribution the method of maximum entropy principle as in [Schönfeldt J-H, Jiminez N, Plastino A R, Plastino A, Casas M 2007 \textit{Physica A} \textbf{374} 573] is used. The obtained distribution is close to exponential one. Another approach to the maximum entropy principle, as in [Van der Straeten E and Beck C 2008 Phys. Rev. E \textbf{78} 051101], except exponential distributions yields power-like, log-normal distributions, as well as distributions of other kind and transitions between them.
