查询词典 point circle

In Figure 5.4, an instance of Point may be part of a polygon or may be the center of a circle, but it cannot be both.

在图5.4中，point的一个实例可以是多边形的一部分，也可以是一个圆的圆心，但不能同时充当这两种角色。

Firstly , the following proofs are made by means of homothet-ic transformation : 1 the centre of a nine-point circle is at the midpoint of ligature of its curcumcentre andorthocentre; 2 the radius of nine-point circle is equal to half of the radius of its curcumcircle.

本文给出一个简单的证法，先用位似变换的方法证明九点圆的圆心在外心和垂心连线段的中点，九点圆的半径等于外接圆半径的一半。

Prominent in the modern elementary geometry of the triangle is the nine-point circle.

九点圆在三角形的现代初等几何中是重要的。

Prom nt in the modern elementary geometry of the triangle is the nine-point circle .

九点圆在三角形的现代初等几何中是重要的。

Instead, when we want to inherit we cast up from Circle back to Point and deal with the initial struct Point there.

相反地，当我们想继承时我们就从圆到点全加在一块，并且在那里直接处理struct Point的初始化。

Zero Point - Circle - Completion of a Cycle when both aspects of your soul merge then blink out.

零点 -循环-当你灵魂的双生子融合一起完成了一个循环周期，灵魂就闪现而去。

When we up-cast from a circle to a point, we do not change the state of the circle, When we up-cast from a circle to a point, we do not change the state of the circle

当我们从圆到点进行向上类型转换的时候，我们不会改变圆的状态，也就是说，虽然我们把一个圆的struct Circle结构看作是一个struct Point，我们却不改变其中的内容。

And the polar angle and the polar radius was represented into AutoCAD polar coordinate, the involute was drawn through the spline linear tool. And then, a section of the involute was intercepted with the diameters of the point circle and the root circle, used it as the tooth face of the spline. The involute tooth thickness was drawn using the diameter of the divided circle and the tooth-form was drawn through rotating, mirroring image and cutting.

根据DIN 3960渐开线花键的坐标值，用EXCEL函数功能计算出不同压力角下渐开线的极角和极半径，表示成AutoCAD极坐标并通过样条线工具绘制出渐开线，再用齿顶圆和齿根圆直径截取一段渐开线作为为花键齿面，并用分度圆直径绘制出渐开线齿剖面，经镜像和裁剪便可绘制出渐开线齿形。

We make a copy of the implementation of points and change those parts where a circle is different from a point. struct Circle gets an additional com- ponent

我们把坐标点的实现复制下来，然后改变那些圆不同于点的地方就可以了。struct Circle多了一个组成

Consequently, the circle viewed as a point still has Circle as a type description because the pointer in its .class com- ponent has not changed. draw is a selector function, i.e., it will take whatever argument is passed as self, proceed to the type description indicated by .class, and call the draw method stored there.

这个被看作是点的圆依旧是Circle类型的，因为其类型描述结构中的。class指针成员没有变化。draw是选择子函数，也就是说，它能接受任何以self参数传来的值，找到由。class指向的类型描述符，并且调用存储在那里的方法。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
