四边形的

But in the new hierarchy of interest, people in different interest stratum have different want and interest expectation. This requires that the reform should look for the'parallelogram of the composition of forces'and meet the interest of the majority in the settlement of contradiction and conflict of people's want and interest.

但在新的利益分层结构中，不同利益阶层的人们的需要和利益追求是不同的，改革应在人们的需要和利益的矛盾与冲突中，寻找"平行四边形的合力"，满足最大多数人的利益追求。

The works of this period are full of painting language experiments in form, space and material, and we see sparks of what would later form his language matrix, but overall, the Chen Yufei of the '80's was a lonely metaphysicist, focused on using the four-cornered world of painting to extract basic imagery and forms from his daily life and spirit. His pictures had a very strong design feel.

这一时期的作品在造型、空间、材料等绘画语言上有着各种实验，闪现出了他其后的一些基本语言与母题，但总体而言，80年代的陈宇飞属于一个孤独的形而上主义者，专注于用绘画这一四边形的世界从他的日常生活及精神生活中抽离出一些基本的意象和形式，画面有很强的设计感。

If many forces are acting simultaneously in different directions on any body, the direction of its motion will not correspond with any one of the forces, but will always follow a middle course, the summary of them, what is expressed in mechanics by the diagonal of the parallelogram of forces.

如果同时有许多各种不相同的力作用于某一物体，该物体运动的方向不可能与任何一个力的运动的方向相符合；而总是平均最短的方向，即力学所说的平行四边形的对角线。

Some models were designed where the unique tetragon and hexagon grids borrowed from the wing structure were used as the basic elements, these models were analyzed numerically, it is shown that the model consisting of tetragon grids is much stiffer than that consisting of hexagon grids, while, more material is used in the first model;crinkling models based on tetragon grids or arched models consisting of hexagon grids become more stiffer than flat ones;hybrid models consisting of tetragon grids and hexagon grids can realize a proper balance between material saving and stiffness improving.

分别提取四边形、六边形的基本网格，建立结构模型，并对它们进行非线性数值分析。研究发现：四边形网格结构刚度大，六边形网格结构刚度小；而从材料利用率角度来讲，六边形网状结构更省材料；起皱对四边形网格结构刚度有加强，而起拱对六边形网格结构刚度有提高；如果将四、六边形的网格进行合理搭配，可以使结构刚度和材料利用率得到优化。

Vortex lattice method is presented for calculating the loading distributions on all blades of propeller and hub which a number of small hyperboloidal quadrilateral panels are discreted.

螺旋桨采用离散涡环法，将桨叶表面和桨毂表面离散为一系列双曲四边形，在四边形网格中布置集中涡环和线源分布，根据物面条件建立方程得到涡和源汇分布的强度。

In the same way as it is possible to modify the angles of Trapezoids and Parallelogram basic shape by moving the yellow dot that is displayed along with the blue resizing handles, it is possible to modify some of the Fontwork shapes.

移动与蓝色大小调整控点一起显示的黄点，可以改变基本形状梯形和平行四边形的角度。以同样的方式，可以修改艺术字的一些形状。

This same anatomic configuration also allows some movement between the crest and the septum, and it is this instability that explains the frequent posttraumatic findings of a displaced quadrilateral septal cartilage from the groove of the crest.

同时这样的解剖特点，也使得鼻中隔和腭嵴之间有一定的活动度，正是这种结构的不稳定性可以解释为什么在创伤后经常容易发现四边形的鼻中隔从腭嵴凹槽上脱位。

同时这样的解剖特点，也使得鼻中隔和腭嵴之间有一定的活动度，正是这种不稳定的结构可以解释为什么在创伤后经常轻易发现四边形的鼻中隔从腭嵴凹槽上脱位。

Through chemical reaction between Ga and NH〓, high-density of regular-shaped GaN nanorods was fabricated on the substrates. The distinct morphology of the GaN nanorods lies in their prism-like out shape and most of them have a quadrilateral cross section.

通过金属镓与氨气反应，制备了大量的具有规则外形的GaN纳米棒，这些纳米棒的典型形貌在于其四边形的横截面。

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。
