正方形的

In the 6th century, Hipparchos, the son of Pisistratus replaced the cairns that marked the midway point between each village deme at the central agora of Athens with a square or rectangular pillar of stone or bronze topped by a bust of Hermes usually with a beard; an erect phallus rose from the base.

在第六世纪，希帕西斯，皮西塔特斯的儿子，取代了堆石界标，标志着雅典城中心市场与每个乡村市区之间的中途指向，连同着正方形或者矩形的石头或铜柱子，顶部是赫密士的半身像，通常是长着胡子，一条直立的阴茎从底部升起来。

Two pairs of vanishing points of orthogonal directions from each image are obtained by using the concept of cross ratio and harmonic conjugate in projective geometry and the orthogonal property of the two diagonals on a square. All intrinsic parameters are calculated linearly after capturing the template from at least three shooting angles. Errors of edge detection and line fitting are avoided because the method does not require image matching.

充分利用了射影几何中交比和调和共轭的知识以及正方形模板对角线相互垂直的性质，根据一幅模板图像可以得到两组相互正交的消失点连线，在至少三个不同方向拍摄的图像上线性求解出摄像机的所有内部参数。

It proved that, when sum of piles, length of piles and diameter of piles were equal, effect coefficient of piles group per m^2 was at the maximum with quincunx laying-out piles, next rectangle and minimum square, the quincunx laying-out piles groups was a better choice than the others laying-out piles group in many eases.

计算表明，当桩数、桩长、桩径相同时，单位承台面积上的群桩效应系数，呈梅花形布桩的最大，呈矩形布桩的次之，呈正方形布桩的最小。因此，呈梅花形布桩群桩是较好的选择。

Firstly a square image is divided in- to two parts by diagonal and a parallelogram is reformed.

首先沿图像的对角线方向将正方形图分为上下两个部分并重新组合成一个平行四边形的图像；然后利用平行四边形图像的两列像素之间的像素数目差将某列中的像素插入到相邻下一列像素之间。

This form of high degree of identification in the Cartier watches and even the circle have a unique status, with a perfect square, vividly demonstrated the wearer tough and simple personality, highlighted by impeccable style of decorative arts.

这种高度的身份在卡地亚手表的形式，甚至圈有一个独特的地位，以一个完美的正方形，生动地体现了穿着者强硬，简单的个性，通过完美的装饰艺术风格突出。

The results show that the most stable P5 is the doublet state of b isomer evolved from regular tetrahedron P4 while the most stable P(superscript + subscript 5) and P(superscript - subscript 5) are the singlet state of e, j isomers evolved from square P4, respectively.

结果表明，最稳定的P5为由正四面体的P4演变来的b结构的二重态，P(上标+下标 5)和P(上标-下标 5)则为由正方形P4演变来的e结构和j结构的单重态。

For two possible geometric structures,square and regular tetrahedron,the electronic structures of ground state and structure parameters of the O_4,O-_4 and O+_4 are calculated according to the principle of minimum energy.

计算了2种可能的空间结构——正方形和正四面体，分别得到了这2种结构的中性分子O4，正一价分子O+4和负一价分子O-4的基态电子结构，并根据能量最低原则确定了各自的结构参数，从而得到了O4分子2种结构的基态总能量、一价电离能及电子亲合势能。

Firstly, this paper uses the method of renormalization group to deal with the Ising Model of equilibrium phase transition and calculate and compare the critical index of the model of square cell with different lattices, which leads to the finding that the size of Kadanoff cell have greater influence on the approximate treatment of interactions between cells.

本文首先用重正化群方法处理了平衡相变的Ising模型，计算了不同格点数的正方形元胞模型的临界指数并进行对比，发现Kadanoff 元胞的大小对元胞间相互作用的近似处理影响较大。

Look at Picture 3.4—2. Compare the area of Square ABCD with the sum of the areas of four same right-angled triangles , and what inequality can you have?

阅读课本 P110，比较图3.4－2中正方形 ABCD 的面积与4个全等的直角三角形的面积之和的大小，你能得到怎样的不等式？

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
