| 摘 要： | 从数值计算发现，对于自治的量子混沌系统，非定态的演化对于扰动非常敏感。除了进一步肯定以前对于非自制系统的结果外，还发现了一些新的现象。经过足够长的时间，即使扰动非常微弱，互作用表象中的矩阵元也要变成随机的分布。规则系统与混沌系统的差别非常显著。

| Abstract: | Numerical results show that,for quantum autonomous chaotic system,the evolution of nonstationary states are sensitive to perturbation.Besides confirming previous results got by other authors in time dependent system,new aspects are revealed.The matrix elements of the evolution operator in interacton picture tend to be a random distribution after sufficient long time,where the interaction is the perturbation,even the perturbation is very weak.Difference between regular system and chaotic one is shown clearly.The calculation is carried out in a SU(3) model. |
