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。

The method transfers the observed data from space domain to 2-D space-time domain by exploiting the cross-correlation of the array outputs,and a large amount of virtual elements are generated through space-time processing.Therefore the constraint over the array configuration and the element identity can be significantly weakened,which means the matching subarray is no longer needed and the advantage of the traditional DOA matrix method,such as automatical parameter alignment and no need of 2-D search,is still available.

该方法在保持原DOA矩阵方法无需二维谱峰搜索和参数配对等优点的基础上，利用阵元输出之间的互相关关系将空域的阵列观测数据变换到时空域，通过空时二维处理在时空域中衍生出大量虚拟阵元，从而大大减弱了传统方法中对阵列结构、排布方式和阵元一致性的约束，不需要匹配子阵，无冗余阵元与孔径损失，并适用于阵元排列不规则的阵列。

We make use of a normal element and circular permutations to construct polynomials over the intermediate extension field between F_q and F_ denoted by F_ where s divides t. The polynomials we constructed are F_q-linearly independent and return elements in F_q when they are evaluated at elements of the extension fields.

结合Reed-Solomon码的构造特点，我们将Chaoping Xing与San Ling所构造的线性码的方法推广到有限域的任意次扩张上，首先利用正规元和循环排列来构造系数属于F_q和F_q的任意次扩域F_之间的中间域的具有特殊性质的多项式，中间域记为F_，其中s为t的真因子，由正规元的选择可以保证所构造多项式的F_q-线性无关性，并且这些多项式在扩域F_中取值都属于F_q，从而构造出一类q元线性码。

Furthermore, in this thesis, we study a problem on the bit permutation network.

此外，在这篇论文里，我们还探讨了一个关於位元排列网路的问题。

The radiation performance at lower frequencies can be improved using the stacked TEM-horn configuration and decreased using rain gutter and square plane TEM-horn configuration.

当TEM喇叭天线阵列单元沿E面叠状排列，阵元间互耦可以改善阵列的低频辐射；沿H面排列的槽状线阵或平面方阵不利于阵列的低频辐射的改善。

Through numerical simulations itwas found that a sandpile model takes on SOC when cellular arrangement submits to a fractal distribution to testify the assumption.

数值模拟表明，元胞排列方式服从分形时，沙堆模型呈现SOC，而等间隔排列的模型不呈现SOC，结果与假设一致。

Young Zhu disclosed that this chapter of he may hit more bonuses originally, because he probably spends 50 Yuan to buy the lottery ticket every day, has "super Lotto", also has "arranges 5", when on June 5 and the wife window-shop passes through 01758 bookies, in wallet only then 20 Yuan pocket money, therefore respectively has bought 5 notes "Lotto" and "arranges 5".

小朱透露，本来这回他可以中更多奖金的，因为他每天大约花50元买彩票，有"超级大乐透"，也有"排列5"，但6月5日与妻子逛街经过01758投注站时，钱包里只有20元零钱，于是就各买了5注"大乐透"和"排列5"。

The fundamental studies on structure sensitive functional materials will provide the necessary knowledge of developing novel functional materials by the way of understanding the relation ship between physical properties and the electronic and geometric structures of the compounds, and will result in the specialized functional moieties and them athematic rules which govern the behaviors of these moieties.
