Firstly, Dempster-Shafer is developed by not only considering the certainty of the evidence, but also considering the average support of the evidence to different subsets in the assignment framework so that it can give more reliable combination result. Secondly, amplitude ratio feature and Euclid distance of the probability density distribution function in Pearson graph from different temporal SAR images are extracted to present change feathers in different scales. Finally, the improved Dempster-Shafer algorithm is applied to fuse the two different features to detect change information of SAR images.

首先通过综合考虑证据本身的确信度和证据对辨别框架中子集的平均支持度进行证据间的加权合成，改进证据理论对证据的合成，提高其可靠性；然后提取不同时相图像间的散射幅度的对比度和概率密度分布函数在皮尔逊图中的欧式距离，两种特征参数代表了像元级和区域级不同空间尺度下微波遥感图像中关于地表变化的信息；最后将改进的证据理论用于两特征之间的融合处理，得到地表的变化信息。

It is shown that two-component Wadati-Konno-Ichikawa equation, i.e. a generalization of the wellknown WKI equation is obtained from the motion of space curves in Euclidean geometry, and it is exactly a system for the graph of the curves when the curve motion is governed by the two-component modified Korteweg-de Vries flow. At the same time, a n-component generalization to the WKI equation is obtained. Also, starting from the motion of curves, mKdV and its symmetry recursion operator is exhibited explicitly; two- and n-component mKdV systems are obtained. It is shown that WKI systems are gauge equivalent to mKdV systems. The two-component WKI equation admits an infinity number of conservation laws and a recursion formula for the conserved densities is given by considering an eigenvalue problem together with introducing an appropriate transformation.

在二维和三维欧氏空间上，我们从空间曲线运动出发，推导出了mKdV方程以及它的用以生成高阶对称的递归算子；推导出了多元mKdV方程以及二元和多元WKI方程，并证明了WKI系统和mKdV系统的规范等价性；尔后，通过考虑特征值问题，并引入一个恰当变换，给出了二元WKI方程的用以计算无穷多守恒密度的递归公式，从而证明了二元WKI方程的守恒可积性；系统地分析了两种mKdV方程的Painleve性质，并分别给出了两种不同形式的二元和n元mKdV方程的共振点出现的规律。

在收到计画书时盖上日期及序号，此方法为使用六个数字，而最前面的两个数字为序号，其后为斜线，再接西元年份的末两位，之后，为小连号，最后为月份。

In the present work, we educed the systematic energy functional of the binary lipid membrane model. And based on the phase kinetics of continuous systems, we established the governing equations for the phase separation in binary lipid membrane under stationary shear flow. Then, by means of the cell dynamical system approach, the equations were numerically solved, intuitively giving out the domain morphologies and membrane shapes.

The algorithms of MUSIC and ESPRIT are introduced, which are the most important algorithms in array signal processing. A method is proposed to make the estimation of the covariance matrix become Toeplitz matrix using the Toeplitz characteristic of covariance matrix.

第2章建立了阵列信号的模型，主要分析了两种无方向模糊的阵列：阵元数大于6的均匀圆阵和非均匀L形线性阵列，并讨论了非均匀L形线性阵列无模糊设计的方法；然后介绍了在阵列信号处理中，两种最主要的算法：MUSIC算法和ESPRIT算法。

There are two main phylogeny analysis methods: distance-based and character-based; and there are two types of evolutionary trees: rooted and unrooted.

在建构演化树时，通常分为距离与字元特徵两种评分方式，有根与无根两种建构方式。

A simple way of saving the memory space is using the 256 ASCII codesby functions such as ACHAR(I and IACHAR in Fortran Compiler to represent 28 egg patterns (or less than 256 patterns). For examples: 00000000 to 11111111 has 256 egg patterns for yes/no data of eight days; 00000 to 22222 (system of no egg, one egg and two eggs) has 35 patterns for egg production of five days; and 0000 to 3333 has 44 patterns for system of no egg, one egg, two eggs and abnormal eggs in four days…etc.

利用诸如 Fortran Compiler提供的 ACHAR 与 IACHAR 对应函数与自建的转换对照表，可以256 (=28)个ASCII字元储存各类变化的产蛋记录；如28 (00000000→11111111)：八天的&有生蛋、没生蛋&的资料或是35 (56)：五天的&没生蛋、一个蛋、两个蛋&的资料或是 44(0000→3333)：四天的&没生蛋、一个正常蛋、两个正常蛋、异常蛋&的资料EEE等。

The atrium was raised to o higher level. The fa ade retreated back about two metres. The Constantinian mosaic floor was covered up with two feet of imported soil and a new marble pavementwas laid at a higher level. The lower part of the interior walls was also covered with marble and the upper parts with mosaics. It was one of these mosaic scenes that spared the Church from destruction during the Persian invasion (614 AD).

中庭被提高了，正面退缩了约两米，Constantinian马赛克地板被覆上两英尺的泥土之后铺上大理石，殿内墙壁下层亦覆以大理石，上层是马赛克，其中一幅马赛克使教堂在波斯人入侵（西元614年）时免於被摧毁。
