四边形的

"A great many people and a great number of circumstances in my old schools crossed each other so as to make up of a resultant force like countless parallelogram in mechanics principle, which directs our outlook on life and value; it is these certain expressions and unforgettable details of some familiar people that are borne in mind memorably, which has formed the four-year history."

"是母校中的许许多多人和事，相互交叉形成合力，像无数个力学原理中的平行四边形，引导了我们的人生观、价值观；正是这些熟悉的人的某些表情和难忘的小细节仍留在记忆深处，才构成了这四年的历史。"

With the exception of this issue which was left free, and which constituted what Folard in his strategical style would have termed a branch and taking into account, also, the narrow cutting arranged on the Rue de la Chanvrerie, the interior of the barricade, where the wine-shop formed a salient angle, presented an irregular square, closed on all sides.

这条未经阻塞留作通道的出路，也许就是福拉尔①兵法中所说的那种交通小道；如果这条小道和麻厂街的那条狭窄的缺口都不计算在内，这座街垒内部除了酒店所构成的突角以外，便象一个全部封闭了的不规则四边形。

In chapter 4,on the basis of chapter 3,a new formulation of hybrid/mixedsingular plate element based on Reissner's plate theory is set up,and 4-node arbitraryquadrilateral hybrid/mixed singular bending plate element formulas including theeffects of transverse shear deformation is derived,then by the use of this method,alarge quantity of numerical computations are carried out,at the same time,the resultsare compared with theoretical solutions and the results obtained by other singularfinite element methods.

第四章 在第三章的基础之上，建立基于Reissner型板理论之上的杂交/混合奇异板单元列式，推导出了考虑剪切效应的四节点任意四边形杂交/混合奇异弯曲板单元公式，并进行了大量的数值计算，同时与理论解析解和其它有限元解进行了比较，计算结果表明：本文提出的杂交/混合奇异板单元方法是可以用于计算含裂纹平板弯曲应力强度因子的一种高效、可靠、简便易行的方法。

A key problem is: is it true that the supremum of the ratios of the moduli of quadrilaterals equals to the extremal maximal dilatation?In this chapter, firstly, for a class of quasisymmetric homeomorphisms with substantial boundary points, we apply a result of Chen Jixiu etc.

在第二章中，我们首先利用了文[16]的结果，研究了单位圆周上一类具有本质边界点的拟对称同胚，证明了它的极值拟共形延拓的最大伸缩商等于四边形模之比的上确界，改进了文[128]的有关结果。

The bending problem of simple-supported parallelogrammic plates on Winkler foundation is reduced to two simultaneous Fredholm integral equations of the second kind by applying Green quasifunction method. The Green quasifunction is set up by using the fundamental solution of Poisson equation and the normalized boundary equation.

应用准格林函数方法，即利用方程的基本解和规范化的边界方程构造一个准格林函数，将Winkler地基上简支平行四边形薄板的弯曲问题化为两个耦合的第二类Fredholm积分方程，此积分方程的核表示式在区域的边界上具有奇异性。

Results: The distance between medial wall of the basal turn of the cochlea and the porus trigeminus was about (10.36±1.50)mm.

结果：耳蜗基底圈的内侧壁至三叉神经孔的距离为(10.36±1.50)mm，下颌神经与岩浅大神经交点和内耳门后缘的连线至三叉神经孔的距离为(8.04±0.99)mm，提出耳蜗的定位四边形。

The image of picture is trapezoid,the image of the tabletop is a irregular four-sided figure, and the image of the rug is actually three seperate regions with more than 20 different sides.

这个图片框的影象是梯形的，桌面的影象是不规则四边形，而地毯的影象则是被分成超过二十边的多边形。

Its accomplishment is simple and intuitional. The main innovation of this method is that we only need construct a symmetric zonal mesh for each interpolated curve respectively and write appropriate knot spacings for mesh edges. Then applying NURCC rules to the initial control polygonal mesh consisting of those symmetric zonal meshes can generate a surface that satisfies interpolation constrains.

该方法的主要创新思想是在被插值曲线的控制多边形两侧构造具有简单对称性质的四边形网格，称为对称网格带，但关键还在于对网格边赋予适当的节点距，并对由这些对称网格带组成的初始控制网格应用非均匀有理Catmull-Clark细分规则，来生成满足插值要求的曲面。

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。
