Two ferrocenyl and trimethylsilyl substituted cyanohydrin ethers have been prepared by the addition of trimethysilyl cyanide to two acetyl-substituted ferrocenes: 1-(1-cyano-1-trimethylsilyloxyethyl)-ferrocene (1) and 1, 1'-bis(l-cyano-1-trimethylsilyloxyethyl)ferrocene (2). The structures of these two compounds were characterized by elemental analysis, IR, 1H NMR and X-ray crystallography.

We construct a family of iterative mappings, which yield cyclic windows of variant size in the dynamical plane by incorporating cosine functions and non-linear angle variables with parameters. Chaotic attractors and filled-in Julia sets in the different cyclic windows are created by establishing the coordinates of any cyclic windows and the maximal window, then clarifying the relationship of corresponding points between these cyclic windows. The respective images in different windows are continuous but with individual structures.

该算法采用余弦函数及含参的非线性角度变量构造一族使动力平面上各周期窗口的尺度变化的迭代映射；通过计算任意周期窗口和最大周期窗口得出窗口间相应点之间的非线性对应关系，并构造出各周期窗口中的混沌吸引子和充满Julia集，其图案是连续的且结构不同的；选用不同的周期窗口作为基本计算区域，使之与正方形像素矩阵对应，并构造出基本图元，实现了用一个映射构造出多个平面排列图案的算法。
