However, while working, Escher realized that falling water could be used to illustrate the impossible triangle in a unique way.

Escher 在作画的过程中意识到落水是一种独特的方式来表现不可能三角形，落水冲下带动轮子，然后再沿着一条砖块渠道流向最低点和尽头，而这又是恰恰是它的最高点和起点。

M. C. Escher's famous print "Waterfall," created in 1961, was inspired by Roger Penrose's impossible triangle.

M。 C。 Escher 作于1961年著名的"瀑布"是受了英数理学家 Roger Penrose 不可能三角的启发。

If you were to draw a triangle using such arcs, you would find the simple theorems of Euclidean geometry would no longer hold.

如果你用这样的弧线画一个三角形，你将会发现简单的欧几里德几何理论将不再适用。

In his early work on general relativity, Einstein realized that over cosmic distances space might not conform to the principles of euclidean geometry - that is, the sum of the angles of a very large triangle might not equal exactly 180

爱因斯坦在早期研究广义相对论时就已认识到，在宇宙规模的距离上，空间是不可能符合欧几里得几何的原理的，这就是说，一个非常大的三角形的内角之和不可能正好等于180度。

The non-commutativity of two gen-erators in an algebra or a group can usually lead to a certain geometrical phase.whose magnitude is generally an area of a circuit(e.g.a triangle)in a certain space.such as the spherical surface or the Euclidean plane.

通常一个群或且一个代数中两个生成元的不对易性会导致某种几何相位。这种相位可能对应于球面或且欧几里德平面几何中某个闭合回路的面积。

In the body in the example, the function can proceeds to general body operation, but is careless of they are circles, exact square still triangle.

在形体例子中，函数可以对一般形体进行操作，而不关心它们是圆、正方形还是三角形。

Output fed to memory is expanded to individual point/line/triangle lists (exactly as they would be passed to the rasterizer).

输出到内存的是独立的顶点、直线或者三角形链表（当然也可能被送到光栅化过程中）。

Based on the theory of tidal flow and sediment motion, a 2-D depth-integrated mathematical model for the Jiaojiang Estuary is developed by using explicit scheme of finite difference on the triangle elements. The results show that the rotary currents occurring in this area can be simply and effectively simulated by the model. Meanwhile, the suspended sediment concentration simulated is in agreement with the field data.

本文根据椒江口实测水文地形资料，从平面二维水流泥沙基本方程和基本理论出发，采用三角单元有限差分法对水流泥沙方程显示求解，对椒江口潮流泥沙进行了数值模拟，模型简单实用，较好地再现了具有旋转潮波性质的椒江河口水流运动特征，含沙量场也得到了基本正确的反映。

1 The Country Point 4 is located inside one of the three Exterior Opposite Angle Area of the triangle.

4.1国家点4落在国家点3、2和1形成三角形的外部对角映射区，此时4色足够

N.1 The Country Point n is located inside one of the three Exterior Opposite Angle Area of the big triangle.

n.1 国家点n落在四点全相邻基本三角的外部三角形的外部对角映射区，封闭于四点全相邻基本三角中的国家点对国家点n而言可以忽略不计，国家点n将最多可以同该四点全相邻基本三角的外部三角形的三个顶点相邻，这时n.1的情况就等同于前述4.1的情况，此时4色依然足够

Don not attempt to do something which you can not to do.

不要企图做那些办不到的事情。

The expression of CTGF and TNF-αweredetected by immunochemistry and the number of Clara Cells was calculated.

光镜下观察肺组织的病理变化，采用免疫组化染色观察肺组织中结缔组织生长因子和肿瘤坏死因子-α的表达和Clara细胞的数量。
