等边三角形

All meshing elements except those are adjacent to edge and transition elements are equilateral triangle, which is very useful for finite element computation.

提出了一种可在平面内进行三角形有限元网格划分的方法，该方法可以在任意二维区域进行剖分；剖分单元除了边界和部分过度单元外，主要为等边三角形。

When you mark a point at 1/4 of that diagonal and repeat the process an equilateral triangle is formed there , and each line as half the diagonal; this is 1/6 of the circle and is called the sextile aspect.

当你在对角线的1/4处做标记，并重复这个过程，也可以形成等边三角形，每条线的长度都是对角线的一半；这就是圆的1/6，叫六分相位。

An equilateral triangle would be formed with its associated 60 degree angle.

一个等边三角形是由关联的60度来组成的。

The epidemiologic triangle consists of three components, with the Host at the top point and the Agent and the Environment at the other two points of an equilateral triangle.

流行病三角形由三部分组成，包括在等边三角形顶端的宿主，和在两个底角处的病原和环境。

Diagram 3 shows triangles E, F, G and H drawn on equilateral triangles of same size.

图 3 显示三角形 E，F，G和 H，它们分别是画在同样大小的等边三角形上。

In general, the triangles of the resulting meshes are close to be equilateral. Experiments also show that the method may yield results of high quality.

一般地，基网格的三角形接近等边三角形，实验也表明该方法能够得到较高质量的结果。

As Yukio Hatoyama wants Japan to interact more with China, the right triangle in which China is at the vertex of a small acute angle and Japan and the US at the other two vertices may become one that is more like an equilateral triangle. Clearly, Yukio Hatoyama sets greater store by China than Taro Aso.

鸠山由纪夫的外交理念是增加与中国的互动，人们也许会看到东北亚中、美、日三角，会由往昔的直角三角形的美日在一边而中国在另一边，调整到类似等边三角形。

The birth of a True Equilateral Triangle from Isosceles parents is the subject of rejoicing in our country for many furlongs around.

一对等腰三角形父母如果生出真正的等边三角形，这在方圆百里都是件大喜事。

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。

Such a birth requires, as its antecedents, not only a series of carefully arranged intermarriages, but also a long, continued exercise of frugality and self-control on the part of the would-be ancestors of the coming Equilateral, and a patient, systematic, and continuous development of the Isosceles intellect through many generations.

正如前例，这样的出身不仅需要一系列小心安排的通婚；而且需要未来的等边三角形的那些所谓的祖先，在节俭与自控方面，进行长期的、连续的训练；另外，等腰三角形的智力要历经几代的努力，耐心的、系统的、持续的发展。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
