By defining a direction phase as the direction of two sequential iterations of the logistic map, a transition of a net direction phase M from zero to a finite value as the parameter &mgr; increases is found. Near the transition point &mgr;(0) a scaling M approximately (&mgr;-&mgr;(0))(alpha) with alpha = 0.5 is obtained. The order state of the direction phases in a coupled map lattice is also studied. A phase synchronization of the direction phases is found although the lattices still remain chaotic.
通过将方向相位定义为逻辑斯谛映射的两个连续迭代的方向,发现随着参数μ增加,净方向相位M从零过渡到一个有限值。在过渡点μ(0)附近,得到标度M近似为(μ - μ(0))(α),其中α = 0.5。还研究了耦合映射格点中方向相位的有序状态。尽管格点仍然保持混沌,但发现方向相位存在相位同步。
