Results ①In 60% of the specimens, the deep dural layer of the lateral wall of CS was incomplete, which was located in the posterior part of Parkinson's triangle or the anterior part of Mullan's triangle;②The length of each side of the Parkinson's triangle was (13.28±3.77) mm,(15.19±3.84) mm and (5.52±1.06) mm respectively; While that of the Mullan's triangle was (15.09±4.12) mm,(8.81±2.38) mm and (10.91±2.03) mm respectively;③ The course of the intra-cavernous trochlear nerve had three types: straight, convex and intercrossed type.

鉴于CS外侧壁深层不完整的原因尚无定论，且国内关于CS外侧壁诸三角和穿行脑神经行径的资料较缺乏〔1～ 4〕，笔者进行了该方面的研究，拟进一步探讨CS外侧壁形态特点，并为临床CS外侧壁手术入路设计、避免脑神经损伤提供解剖学基础。1 材料与方法成人头颅湿标本 15例(30侧)，经福尔马林溶液固定，动脉灌注红色乳胶

During building the 3D mode, I use the concepts of point, triangle, plane and block, that is from point to triangle to stratum surface or fault to closed block, and finally all the closed block will form a 3D model. Especially the auto-adaption triangle grid method for interface fitting and the 3D visualization technique for building 3D model are the feature of our method.

在三维建模中，引用点、三角形、面、块的概念，即由点形成三角形面，由三角形面形成地层面或断层面，再由面围成封闭的块，所有块构建成三维模型；其中提出了自适应界面拟合三角形网格方法及用于三维模型建立的三维可视化技术等。

He is known for familiar results in elementary geometry; for example, the Euler line through the orthocentre (the intersection of the altitudes in a triangle), the circumcentre (the centre of the circumscribed circle of a triangle), and the barycentre (the "centre of gravity," or centroid) of a triangle.

他作了很大努力来发展一个较完整的月球运动理论，它由於包含了三体问题而特别困难；在1753年发表的部分解答曾帮助了不列颠海军部对月球表的计算。1772年，通过艰钜的心算完成了他的关於月球运动的第二种理论。

Structure form adopts converse triangle beam double-hole connection welded by general electric trolley wall plate and steel plate, connection shaft, triangle beam bottom is connected with girder by nut and thrust bearing, triangle beam could rotate 360 degrees horizontally, thus realize whole set electric trolley horizontal rotation, largely reduce curve track curvature radius of electric hoist traveling mechanism.

描述： 结构形式采取通用电动小车墙板与一个钢板和连接轴组焊的倒三角形吊梁双孔连接，三角吊梁下面通过螺母及推力轴承与一个横梁连接，三角吊梁相对横梁可在水平方向做360度旋转，从而实现电动小车的整体水平方向转动，大大减小了电动葫芦运行机构弧形轨道曲率半径。

This is a right triangle(isosceles triangle/ equilateral triangle).

这是一个直角三角形。

The program incorrectly classifies this triangle as a scalene triangle instead of classifying it as an isosceles triangle.

程序错误的把这个等腰三角形划分成了不等边三角形。

If appear special triangle, wait like isosceles right-angled triangle or equilateral triangle, so the problem can apply special methodological processing.

假如出现非凡三角形，如等腰直角三角形或等边三角形等，那么新问题就能运用非凡的方法处理。

With the method and the relation between the center of a circle and a triangle, the relation between the triangle and the circle can be determined rapidly, hence to quickly and correctly determine the position relation between the projections of the triangle plane and the tool in tool axis direction, and raise the efficiency of 3-axis NC machining.

借助于该方法及圆心相对三角形的位置关系，可以快速判别三角形与圆的位置关系，从而能据此快速、准确地判别三角片与刀具两者在刀轴方向投影的位置关系，提高3坐标数控加工干涉检查的效率。

Because the triangle mesh was widely used in industry and computer graphics systems,a computation method for offset curve on triangle meshes was proposed,where the curve on the triangle mesh was defined by a sequence of points with every point lying on the mesh.

鉴于三角网格在图形系统和工业界广为使用，提出了一种三角网格上曲线等距线的计算方法，其曲线表示为位于三角网格的点序列连接而成的空间折线。
