垂直距离

This is my last OpenGL for a project to use the "three-dimensional vector space / point" and related functions, they can use a definition of space vector / points, for the vector translation, zooming and rotation, the use of correlation function can also achieve two vector by the fork, get a Vectors absolute length of a vector unit, received a 3:00 decision vector perpendicular to the plane, a space to be the distance between two points, two vector to be the plot points, to be the angle between two vectors, such as operating for the use of user-friendly, each function is detailed Notes, it is particularly important if the calculation vector plot points, fork also took note, we hope to have useful.

这是我过去进行一个OpenGL项目时使用到的"三维空间向量/点"类及相关函数，使用它们可以定义一个空间向量/点，实现向量的平移，缩放和旋转等，使用相关函数还可以实现两向量的叉乘，得到一个向量的绝对长度，将一个向量单位化，得到一个三点决定的平面的垂直向量，得到空间中两点的距离，得到两向量的点积，得到两向量的夹角等操作，为方便用户的使用，每个函数都有详细的注释，特别重要的向量计算如点积，叉乘还有相关说明，希望对大家有所用处。

If the observer is at a great distance compared to the other dimensions of the experiment and the rays are nearly perpendicular to the reflecting surfaces, then the path difference between the two waves (corresponding to r1-r2 in the preceding section) is just twice the thickness d of the air wedge at each point.

如果观察者比起实验装置来讲距离较远而且光线较接近于垂直反射于表面，那么这两光波的光程差(在前面所述的相应部分 r1-r2)就仅仅是空气劈尖在该点处的厚度 d 的两倍。

The stifle shows good functional angulation, and hock to heel is short and perpendicular to the ground.

膝关节显示出良好的角度，飞节到后跟的距离短，且垂直于地面。

通过读数望远镜垂直移动，确定十字线的像和样品最后表面的顶点的距离。

By adding a vertical border or padding, the margins no longer collapse and the height of the element is calculated as the distance between the top and bottom margin edges of its contained children instead.

通过添加一个垂直边框或填充，空白边就不再叠加了，而且元素的高度就是它包含的子元素的顶部和底部空白边边缘之间的距离。

The combined motion of grinding the transition arc maintains that the gyration center of the arc moves along the parallel line to the surface of the grinding wheel, and the gyration center of the oxide tool moves along the vertical line to the surface of the grinding wheel.

磨削刀片过渡圆弧时，过渡圆弧的回转中心到砂轮面的距离必须恒等于过渡圆弧的半径，磨削过渡圆弧的复合运动要保持过渡圆弧的回转中心沿平行于砂轮面的直线运动；刀片的回转中心沿垂直于砂轮面的直线运动。

The movement equation of droplets was set up and the expression about flying distance and vertical drop-down height variation with time of charged particle was obtained.

建立了荷电雾滴的运动方程，获得了喷雾粒子的飞行距离和垂直降落高度随时间变化的显式表达式。

You are at a distance R from the center of rotation, the carousel rotates at constant angular velocity ω, and the raindrops fall straight down with speed v.

你离旋转的中心还有一段很长的距离，那个传送带保持着有着尖角的速率旋转，还有那个雨滴垂直用一个v的滴下来，那里没有风。

Trail --the horizontal distance between the front end's point of rotation (i.e. where a line drawn through the steering head would intersect the ground) and the contact patch of the tire.

拖拽――前端转向点与前胎与地面接触点的水平距离（从通过摩托车的转向把头的一条线上垂直到地面的一个假想焦点，然后从这个焦点折回到轮胎与地面接触点的水平距离。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
