In this research a new mathematical model - cubic polynom with two given derivatives at end points - was proposed which can good match the S-shpae curve.This model has a number of analytical features:describing the geographic phinomena prosesses in three hierarchies (textural fractal,structural fractal and state fractal); the boundary values of the structural fractal can be considered as the boundary values of interval of scaleless.

在研究中提出了扩展分维表达函数：带导数三次多项式，它能很好地表达反S形分布曲线，具有一系列解析特征：可从三个层次（纹理分形、结构分形和态势分形）上描述地理现象或过程；其中结构分形的边界可近似地看作是非扩展分维无标度区的上下界。

This research method is independent of Green"s function and variational structure. So it can tackle with the BVP for non self-adjoint and self-adjoint difference equations and overcome the difficulties brought about by the establishment of Green"s function, a study of the sign and the estimate of below and above bounded for Greens function.

本章的研究方法既不依赖于Green函数又不依赖于变分结构，因而能解决非自共轭的差分方程边值问题，且克服了Green函数的建立、其符号的判断及其上下界的估计给研究带来的困难，该方法同样适用于研究自共轭的差分方程边值问题。

Suppose that f is a real-valued ω〓-lower semicontinuous function defined on a ω〓closed bounded subset A〓 of the dual E〓 of a locally convex space E, which is bounded below on A〓, and suppose every ω〓 closed convex subset of C〓≡ω〓-clcoA〓 is the ω〓closed convex hull of its w〓-β-exposed points.

假设X是一个局部凸空间，X〓是其对偶。A〓是X〓上的ω〓有界闭子集，f是A〓上的ω〓-下半连续实值函数且在A〓上下有界。

The bounding surface may be whether a wall, a fence, or an abstract line or plane. Orientational metaphors of idioms give concepts of an idiom spatial orientation.

习语的方位隐喻特征指的是，人们在习语中参照上下、内外、前后、深浅、中心一边缘等概念建构的隐喻。

Among them, the most eye-catching is delicate stage lighting and fluctuation two layers of tectonic create successive surprise, but with a pearl, bowknot, huge high-heeled shoes, colourful box is complete the element such as the theme.

其中，最为吸引眼球的就是精致的舞台，绚丽的灯光和上下两层的构造制造出接连的惊喜，而用珍珠、蝴蝶结、巨大的高跟鞋、色彩缤纷的礼盒等元素则完整了演出的主题。

After the part is "Chinese culture, summed up the" middle hollow mahogany pillars of the upper and lower points of two parts, the box is putting the "family autobiography," Under the box is putting the "home grown" come together is a complete set of "Chinese image of the sculpture" gifts.

后部分是"中国文化的概括"中间红木支柱是空心分上下两部分，上盒是放"家庭自传"下盒是放"故乡土"合上门就是一套完整的"中国人形象雕塑"礼品。

Based on the point that there is something in common between the rules of matrix multiplication and the figure connection in braid multiplication, this paper gave a new representation of braid group called node matrix representation.

利用矩阵乘法规则与辫子乘法中图形的上下对应连接有类似之处这一特点，提出一种用结点矩阵表示辫子的方法。

China Petrochemical, China's oil break-even point in almost 90 U.S. dollars up and down, and yesterday's price has fallen to below 91 U.S. dollars.

中国，中国的石油石化突破，甚至在几乎九十○美元点上下，和昨天的价格已经下降到低于九十一美元。

Or who can come to him with his double bridle?

The result shows that the technical style of our athletes used is that stride length is shorter and stride frequency is larger,the buckjump time of our players is located at the floor level of the foul limit,the knee angel is unwind from touchdown on upright phase,in the sprint phase,the kneel angel is blurry from touchdown to upright phase,the uprightness displacement of body center and vertex are higher than the international athletes, this since stretching to leave a ground of opportune moment to be partial to early and making an effort action insufficiency with leg driving of the ankle joint relevantly, also with the leg put of front stretch is not enough active at the touchdown ground moment.

结果表明，我国运动员在后半程中，运用的是步长较短，步频较快的技术风格；腾空时间总体上处于犯规时限的下限，膝关节从着地瞬间直至垂直支撑面保持了可见的伸直状态，但在最后冲刺阶段，膝角出现了模糊伸直过程；身体重心垂直位移、头顶位置上下起伏均高于世界优秀运动员平均水平，这既与踝关节后蹬伸展离地时机偏早、用力动作不充分有关，也与着地瞬间摆动腿前摆后的前伸着地动作不够积极有关。
