摘要

对于在 Feigenbaum 临界点处的标准 logistic 图的时间演化进行 Tsallis 熵分析时,已知存在唯一的熵指数 qq^*,使得渐近增长率 Kqlimt{Sq(t)Sq(0)}/tK_q \equiv \lim_{t \to \infty} \{S_q(t)-S_q(0)\} / t 为有限值,而当 q>q(q<q)q > q^* (q < q^*) 时,KqK_q 为零(或发散)。我们证明了尽管整个时间演化无法被分解为独立子区间时间演化的乘积,伪可加条件熵 Sq(t0){Sq(t)Sq(0)}/{1+(1q)Sq(0)}S_q(t|0) \equiv \{S_q(t)-S_q(0)\}/ \{1+(1-q)S_q(0)\}q=qq=q^* 时变为可加的。讨论了 KqK_{q^*} 与条件熵增长率 KqSq(t0)/tK'_{q^*} \equiv S_{q^*}(t | 0) / t 之间的关系。
