查询词典 equilateral triangle

In addition to creating zone of stability in the Moon's orbit in which to build permanent space habitats, the Lagrange librations points have a unique geometry, such that three of the points form an equilateral triangle and two of those three points form congruent equilateral triangles with the Earth and Moon.

此外，可以在月球的轨道创造稳定区域，来建立永久性的太空栖息地。拉格朗日点有一个独特的几何形状，例如有三个点（L3、L4、L5），形成等变三角形。而这三个点中又有两个（L4、L5），和地球月亮构成两个等边三角形。

Triangle pushes forward the brand strategy which highlights science, quality and market, and the business conception of "people oriented". Triangle tires have successively passed the authoritative certifications of DOT, ECE and CCC, tire major performance index has reached international advanced level. Triangle has more then 139 patents, 26 of them are invention patents. The project of "Jumbo OTR tire manufacturing technology and equipments development" was awarded as national scientific development first-class prize, which is the first greatest honor for tire enterprise across China. Triangle brand became the first tire enterprise in China that got the certification of "China far-famed trademark" and "China famous brand product".

In this paper was obtained minimum point of sums of distances to isosceles triangle certainly was in median line of base of the triangle,and minimum point of quadratic sums of distances to every vextex in general triangle just was bara-center ofthe triangle.

对等腰三角形，得到了到各顶点距离之和的最小值点必在底边的中线上；对一般的三角形，获到了到各顶点距离平方和的最小值点就是三角形的重心。

From calculating the maximum distance between the vertexes and their related average plane for each triangle, and based on the triangle area, surface attribute and the predefined characteristics, the algorithm gives out the triangle's weight, the collapse orders of triangle and makes a continuous level of detail model.

算法计算三角形顶点到相关平均平面的距离的最大值，结合三角形的面积、表面属性和预设特征给出三角形权值，确定折叠次序；并能够用累进网格实现连续的层次细节模型。

Based on the study of triangle mesh of creation algorithm, include the arithmetic of regular data make triangle mesh and irregular data make triangle mash. The paper put forward a optimized triangle mesh algorithm. Its key point is divide data into pieces in advance, then set up the net. The experiment result shows that this algorithm improves not only the efficiency of terrain molding, but also the precision compared with the old algorithms The main purposes of this paper are research visualization algorithm of three dimensions and the arithmetic of terrain visualization.

本文研究了基于三角形网格的地形建模的基本理论和方法，包括规则数据的三角网生成以及不规则三角网 TIN 的生成算法，总结了前人在这些方面所做的工作，本文提出了一种优化的三角网格生成算法，实验结果表明，该算法不仅提高了地形建模的效率，而且所生成的三角网格模型与以往算法相比精确性也有很大的提高。
