This thesis has mainly contributed two results in theory: one is that the covariance matrix is not positive definitive if the number of sampling is least than the number of variables, the other is that the covariance matrix of discrete sample is positive definitive if and only if the sum of every random column vector of data matrix is non I-linear combination.

本论文在理论上，主要得出两个新的结果：ⅰ抽样调查中，若样本的个数少于变量的个数则样本协方差矩阵恒为非正定；ⅱ离散型样本协方差矩阵正定的充要条件是样本资料阵的各随机列向量是非I-线性组合。

Extended the semi-analytical finite element method into the Dugdale model of elastic-plastic fracture mechanics, the analytical elements based on the Dugdale model of mode Ⅰ and mode Ⅱ crack are constructed. The formulas for the stiffness matrices and load vectors of analytical elements are deduced.

In chapter 3, on basis of the first order shear deformation theory, a series of composite laminated beam elements are developed, which are plied transversely, longitudinally and/or assembled both, respectively. A geometric nonlinear element stiffness matrix for the transversely plied laminated beam is presented.

第三章首先介绍了目前已有的在小变形下的横向层合梁、纵向层合梁和组合层合梁理论，并推导了其相应的有限元列式，然后又基于Von-Karman大挠度理论的几何关系，推导了大变形下横向层合梁的单元切线刚度阵。

In Chapter 5, a new method with direct partitioned column updates of cholesky factorization for solving large scale sparse unconstrained optimization problems is proposed, which depends on a consistent partition of the columns and cholesky factorization of the Hessian matrix.

第5章基于稀疏Hesse阵的列的相容分划，并在其Cholesky分解的基础上建立了求解大型稀疏无约束优化问题的直接校正Cholesky因子算法。

Recently, it is a hot research at home and abroad in portioning groups of the matrix to iteration which is based on the structure of the Hessian.

近年来，结合稀疏Hesse阵的结构，按照分划组的思想将矩阵列分划进行迭代是国内外研究的一个热点。

Optimizing and Realization of the Finite Field Inversion Algorithm Based on FPGA;2. The stability and operation of the inversion formula for Toeplitz matrices are also considered.

利用两个线性方程组是否有解给出了Toeplitz矩阵可逆的条件，表明Toeplitz矩阵之逆阵可以表示为φ-循环矩阵与上三角Toeplitz矩阵的乘积之和，给出了其逆矩阵列的递推公式，得到了求Toeplitz矩阵之逆矩阵的快速算法。
