构造上的

First, we introduce the concept of polarizable Carnot group and give some new properties of its homogeneous norm. Then we construct a class of non-divergence equations as well as their nontrivial solutions. The failure of corresponding A-B-P type estimate and uniqueness to the Dirichlet problems in space~ follow.

首先引入可极化Carnot群的概念，给出了可极化Carnot群上齐次模的若干性质，然后构造了一类非散度型次椭圆方程及其非平凡解，由此证明此类方程Dirichlet问题的解在函数空间L~中不唯一，进而证明相应的Alexandrov-Bakelman-Pucci型估计不成立。

Based on analyzing the advantages and shortcomings, especially the membrane effects, of X steel plate yielding energy dissipator, and combined with the mechanism characteristics of Pall frictionalenergy dissipator, a composite steel plate yielding energy dissipator has been developed. Then the hysteretic behavior of CSEDOR has been tested.

本文在充分利用钢板屈服耗能器性质稳定、耐久性好等优点的基础上，针对x形钢板屈服耗能器中存在的薄膜效应，结合Pall摩擦耗能器独特的构造特点，提出了工程可用的组合钢板屈服耗能器，并进行了这种耗能器的滞回特性试验和疲劳性能试验。

The divisor class group, often called Jacobian group, based on which hyperelliptic curve cryptosystems are constructed, is much complicated than the elliptic curve rational point group.

但由于可以在一个很小的基域上构造具有较大素数因子阶的Jacobian群，且可应用于密码体制的超椭圆曲线比较丰富，这使得超椭圆曲线密码体制也逐渐受到人们的重视。

On the basis of the frame of dodecahedron, we apply the method of "spherical stretching" to the frame, we can obtain a novel polyhedron with I_h symmetry, which contains 72 pentagons.

我们在十二面体框架的基础上，利用"球面拉伸"的方法，得到新的具有二十面体对称性，72个五边形构造的的多面体结构。

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.

将上面的半解析有限元法应用于弹塑性断裂力学中的Dugdale模型，分别构造了基于Ⅰ型和Ⅱ型Dugdale模型的裂纹解析元，并建立了解析单元的出口刚度阵和荷载向量的列式。

By using the Groebner bases theory and elimination theorem, we constructed a new algorithm of the algebraic attacks on nonlinear combiners with memory based on the previous works, and also analyzed its computation complexity in detail.

在已有工作的基础上，利用Groebner基理论及消元定理，构造了一种新的对带记忆非线性组合生成器的代数攻击算法，并对算法的计算复杂度进行了分析。

Around TLDM, we discuss the definition, representation, calculation and reasoning of their relationships in two-dimensional space. TLDM also considers map design and spatial analysis based on equivalence class.

为此，本文提出并实现了一个面向对象的三级地图数据模型TLDM，并围绕该模型讨论了二维平面上地图对象以及空间关系的定义、表示、计算和推理、地图的构造和输出以及基于等价类的空间分析等。

The skeleton of Sapeornis has several unique features, such as a distinctively elongated fenestra on the proximal end of the humerus, a robust furcula with a distinctive hypocleidum, and an elongated forelimb.

那么这一件比较完整的会鸟标本，我们可以看到，它的翅膀上还保存了爪的构造，另外它的尾巴，但是已经十分缩短，这一点特征已经和其他进步的鸟类非常相似。

Poptosis-inducing factor is a mitochondrion-localized flavoprotein with NADH oxidoreductase activity, which is encoded by the nuclear gene. Following induction of apoptosis, AIF is released from mitochondria and translocated to cytosol, and then to the nucleus. The mechanism of AIF translocation from mitochondria to nucleus is still unclear. It has been suggested that translocation is due to the presence of nuclear localization signal.

bstract： AIF(apoptosis-inducing factor)为位在粒线体内膜膜上之蛋白质，在正常细胞中，能够藉由维持电子传递链复合体I的稳定性，进而影响细胞能量的产生及自由基的清除，并且也会维持粒线体的构造；反之，当细胞遭受到不当刺激时，粒线体膜通透性改变，使得原本存在於粒腺体间质中之AIF，被释放出来，进入细胞核内造成DNA片段化，进一步促进细胞凋亡。

The first ever Olympics for the world's most populous nation, 1.3 billion who frame the front-page story of the 21st century.

这个第一次举办奥运会的世界上人口最多的国家，亿的中国人构造出 21 世纪的故事 13 头条。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
