To this end, we systematically investigate the some properties of m-band compactly supported orthogonal multiwavelets system related to each type symmetric center filter.

从一个给定的具有对称性质的m带紧支撑正交多尺度函数出发，欲构造也具有对称性质的m带紧支撑正交多小波，可转化为对给定矩阵的对称仿酉扩充问题。

This article begins with the I/O description of the system, then turns to the state space of linear time-invariant continuous system. It elaborates how to establish the controllable standard model of Gramian matrix and how to realize it, furthermore the article provides a analytical bridge circuit.

由系统的输入－输出描述法着手进而介绍线性定常连续系统的状态空间描述，详细阐述了格兰姆可控规范型矩阵的构造和实现步骤，并就此情况给出了一个具有较高分析价值的桥式电路。

These constructional methods can be used to treat many problems, the numerical results show that the given interval extension has smaller excessive width relative to the range of the functions over a domain. For univariate differentiable functions, the definition of interval slope is extended from the first order to high order according to their differentiability, and iterative formula of high-order interval slope computation is also developed.

对多元函数，在不要求函数的可微性及有关Lipschitz常数的条件下，给出了分量函数区间展开的斜率算术运算规则；利用函数局部凸或凹的运算特点，通过递归计算建立了多元函数区间扩张的构造方法。

Second, the theory of scale space was used to design a new operator for target detection and tracking. Then, the property of scale invariant was analyzed and proved, and a tracking scheme based on the gradient LOG operator was proposed. Experimental results show that the gradient LOG operator is appropriate to describe small target in complex background, and the detection precision is in the level of sub-pixel. Furthermore, it is efficient and robust to noise.
