用解析和数值计算方法研究了二维耦合映象格子系统的斑图动力学。两个有趣的时空周期图案解析求解。通过线性稳定性分析，得到了小系统的稳定性边界。当系统尺寸与缺陷的空间周期性不匹配时，会出现冻结的随机混沌缺陷团和缓慢随机传播的混沌缺陷串。
The pattern dynamics of a two-dimensional coupled map lattice system is studied using both analytical and numerical calculations. Two interesting spatiotemporal periodic patterns are solved analytically. Their stability boundaries for small system size are obtained by linear stability analysis. As the system sizes mismatch the spatial periodicity of the patterns, a frozen random chaotic defect cluster and a slow random propagated chaotic defect string appear.
