The relaxation time approximation (RTA) is a well known method of describing the time evolution of a statistical ensemble by linking distributions of the variables of interest at different stages of their temporal evolution. We show that if all the distributions occurring in the RTA have the same functional form of a quasi-power Tsallis distribution the time evolution of which depends on the time evolution of its control parameter, nonextensivity q(t), then it is more convenient to consider only the time evolution of this control parameter.

超越松弛时间近似

弛豫时间近似 (RTA) 是一种众所周知的方法，它通过将感兴趣的变量在其时间演化的不同阶段的分布联系起来来描述统计集合的时间演化。我们表明，如果 RTA 中出现的所有分布都具有相同的拟幂 Tsallis 分布的函数形式，其时间演化取决于其控制参数非延展性q ( t )的时间演化，那么更方便地只考虑这个控制参数的时间演变。
