We construct a kind of special matrix function, which is used to characterize the minimization property of this iterative method, and prove that the approximate solution, generated by this iterative method, minimizes this kind of matrix function over a special affine subspace, which means that the Frobenius norm of the residual sequence is strictly monotone decreasing.

通过构造一类特殊的矩阵函数来刻画该迭代方法的极小化性质，并证明了由该迭代方法计算出来的逼近解，可使得这类矩阵函数在一个仿射子空间上达到极小，而且所得到的残差序列的Frobenius范数是严格单调递减的。

Based upon object morphism, notions of object aggregation, specialization, inheritance, reification and class are interpreted in this model further.

基于对象态射，本文进一步给出了对象聚合，特化、继承、精化和对象类等概念在此模型中的解释。

In addition,the one complex containing benzoaza-15-crown-5 pendant has a relatively higher catalytic activity over another one containing morpholine,which may be due to the preponderant effect of hydrophobic environment of the former.

Schiff碱类金属配合物除在氢化反应、环氧化反应、聚合反应、仿生催化氧化等方面得到广泛的应用外[5]，近两年来，我们发现Schiff碱金属配合物也能有效地促进酯的水解或剪切4

Genespring 6. 1 was used to normalize and cluster data.

Different from the traditional approach of solving GDA by singular value decomposition,the new algorithm utilizes kernel modified Gram-Schmidt orthogonalization algorithm to extract the optimal transformation matrix directly,which can not only effectively hold the most discriminant information in the null space of within-class scatter matrix,but also make the solution more stable in numeric.

与传统用奇异值分解获取目标特征子空间的方式不同，新算法运用核修正格兰-施密特正交化过程直接提取最优投影变换矩阵，不仅有效地地保留了类内散度矩阵最具辨别力的零空间信息，同时使所求解在数值上更稳定。

By means of Floquet theory,Lyalpunov function, Hurwitz criterion, linearization, Lasalle invariable set principle,, characteristic line, coincidence degree, estimation of inequality ,numerical simulation and so on, we study two kinds of models with impulsive vaccination.

其中综合运用Floquet 原理、Lyapunov函数、 Hurwitz判据、线性化、 Lasalle不变集、数值模拟、射频映射、分支理论、不等式估计、重合度理论等方法和知识，系统地研究了两类实施脉冲疫苗策略的非线性模型。

Oilcan is a kind of typical rigid target with big backscattering coefficient, which takes on point figure if the resolution of SAR image is not very high; these point targets to be recognized gather together, and form a target region with some distribution area; the center of the region appears as a beeline, and the speckle noise appears scattered, therefore, considering the different grey distributions between point target and speckle noise region and the space geometry distribution, these point targets can be recognized by this algorithm.

由于在高分辨率情况下，合成孔径雷达图像中油罐个体的散射分别体现为由若干高亮度点围成的椭圆，待识别油罐目标的模糊边缘呈不连续的椭圆状，因此从二值化后的SAR图像中识别出拟目标的不连续边缘，判断其是否满足目标边缘特性来识别出最终结果，采用该方法解决了这类高分辨率下椭圆状目标的识别问题。本文运用了基于Gauss核函数支持向量机的SAR图像典型目标识别方法。

This article studies solution of the first kind of operator equation and makes theoretical analysis and algorithm in detail.

讨论了地球物理反演问题中的第一类算子方程的解法，基于Tikhonov正则化思想，给出了详细的理论分析和算法描述。

Objective: To investigate immunological mechanism of corneal melting, perforation and ophthalmitis after alkali burn. Methods: A model of severe corneal alkali burn was established in rats. Immunohistochemical method was carried out on wholemounts of the cornea, iris, choroid and retina at different time after corneal burns to detect MHC class Ⅱ positive cells.

在大鼠角膜上制作碱烧伤模型，在烧伤后的不同阶段，制备角膜、虹膜、脉络膜以及视网膜铺片，采用卵白素-生物素过氧化物酶免疫组化方法，检测眼组织MHC-Ⅱ类抗原阳性细胞。
