Pattern formation in spatiotemporal chaotic systems is investigated. Temporally chaotic and spatially ordered patterns are observed by varying the coupling strength. Spatial orderings emerge spontaneously due to self-organization of partial and nonlocal chaos synchronization, governed by various types of spatial symmetries. The first and secondary bifurcations from spatially disordered chaos to chaos with different levels of spatial orderings are observed and the scaling behaviors associated with these bifurcations are statistically analyzed.
研究了时空混沌系统中的模式形成。通过改变耦合强度观察到时间上混沌而空间上有序的模式。由于部分和非局部混沌同步的自组织作用，空间有序性自发出现，这由各种类型的空间对称性所支配。观察到从空间无序混沌到具有不同空间有序程度的混沌的一级和二级分岔，并对与这些分岔相关的标度行为进行了统计分析。
