轭

Since the B-spline is a locally supported function, the smoothing formula can be strictly limited in a neighborhood of each point. The smoothing surface defined by the smoothing formula has the same convexity as that of the original image. Secondly, the edge points are detected by either computing the local extremum points of the directional derivative or computing zero-crossing of the second-order directional derivative of the smoothing surface. Finally, an example of an edge detector is given.

针对反卷积视觉模型的病态性，增加了适当的约束，给出了基于低松弛迭代格式的快速自适应滤波算法，对于一个N×N输入图象，由于变换核的局部支撑性质以及低松弛迭代格式的引入，使得快速自适应滤波算法的计算复杂度降为象素个数N〓的线性量阶N〓，就最小二乘算法的复杂性而言，优于不动点迭代算法的O以及基于FFT的预处理共轭梯度算法的O。

The interesting differences are attributed to the dissimilitude in the molecular structures of C〓 and C〓.

值得注意的是，由于C〓独特的分子结构，它展现了与常见的共轭体系和C〓完全不同的双光子吸收过程。

Like Rousseau, they desire to force mankind docilely to bear this yoke of the public welfare that they have dreamed up in their own imaginations.

像卢梭一样，他们渴望强制人类温顺的套上公共福利的轭，而所谓的公共福利不过是他们在做梦的时候想出来的东西。

The introduction of line searches requires the solution of sub-problems must be a dropped direction, that is g T k δ k 0, In this paper, we study the existed methods of solving sub-problems, prove Zhang and Xun 1999's dogleg method and Steihaug 1983's conjugate gradient method to meet the condition of adequate decrease, then the solution can be used in line search.

引入线搜索要求子问题的解必须是下降方向，即g T k δ k 0，本文研究了现存的子问题的求解方法，证明了Zhang和Xun1999折线法、Steihaug1983共轭梯度法满足"充分下降条件"，得到的解可以安全实施线搜索。

Taking the Mentougou District in Beijing as an example, a comparative study was made on the three modes of ecological rehabilitation, i.e., gradual ecological rehabilitation based on realistic ability, ecological rehabilitation based on government dominancy, and conjugated ecological rehabilitation based on complex ecosystem theory.

本文以北京市门头沟区为例，对比研究了生态修复的3种模式：基于现实能力的渐进式生态修复、基于政府主导的强势生态修复和基于复合生态系统理论的共轭生态修复3种模式。

Since most of the large molecules containing phosphorus element have double bonds, it is necessary to consider the special structures of double bonds in order to deal with these large systems more accurately. So, based on density functional theory and electronegativity equalization principle, applying a general atom-bond electronegativity equalization method , using separated program, through regression and least-squares optimization , the parameters of atoms and bonds in molecules are determined . By these parameters , the charge distributions and the energy of some molecules containing phosphorus element, especial the fragment of DNA, RNA, are calculated . The results are quite good.

由于这些含磷生物大分子体系都含有双键，为了明确的处理双键，进而更准确的解释带有双键和共轭双键的含磷生物大分子结构与性质的关系，我们以密度泛函理论~([1-4])和电负性均衡原理~([5-9])为基础，应用和开发原子-键电负性均衡方法中的σπ模型，利用最小二乘法，拟合确定了一些分子（含碳、氮、氧、氢以及磷等原子）的各种类型原子及化学键区域的参数，并利用上述参数计算了一些多聚核苷酸的电荷分布以及分子的总能量，进行了讨论，得到的结果可以和从头算相媲美。

In addition, a series of double stranded polymers by using furan-containing oligoaryls as linkers was synthesized.

另一方面，我们将连接降冰片烯骨架的基团，以一系列不同共轭长度的苯环呋喃交错寡聚物取代。

Remove the yoke from, as of a draft animal.

Harness:The gear or tackle, other than a yoke, with which a draft animal pulls a vehicle or an implement.

挽具：一种与轭不同的用于将驮重动物系在车辆或工具上的马具

She gently rebuff ed him, but agreed that they could be friends
