Met! True art thou, lad, as the circumference to its centre.

握一握！孩子，你真像圆周对圆一样忠诚。

The mirrors are placed in concentric semicircles facing a tower, on top of which the boiler and the turbine sit.

高塔处于荧屏所在中位置，所有定向反射镜则以高塔为圆，呈半圆形分布。

The crime scenes are centered on 2 separate locations.

现场以两个独立地点为圆。

Another popular brainstorming technique is to radiate your ideas out from the center of a circle.

另一种流行头脑风暴技巧是将您想法从圆向外辐射。

This is the only way, we say; but there are as many ways as there can be drawn radii from one center.

常说，这是唯一生活方式；但其实生活方式还有千万种，就像以从同一个圆画出无数条半径一样。

If you draw a circle centered at the origin, say with radius 10, how many lattice points would you guess are inside that circle?

如果你画一个以原点为圆圆，假设半径为 10， 你猜这个圆内有多少个格点？

That means this car, this reference frame, has a  centripetal acceleration which is directed in towards the center of the circle which is  to your right.

这意味着这辆车， 这个参考系，有一个向加速度， 方向朝向圆， 也就是你右边。

Diameter is the distance across a circle, the length of the line that goes through the center of a circle and touches both sides of a circle.

直径是穿过圆距离，即通过圆并与圆两边相交直线长度。

And distance, in this case, if she's doing a giant, is the circumference of a circle traced out by her center of mass as she goes completely around the bar.

在这种情况下，如果她做是大摆动动作，距离是她绕杆一周时，以其质量中为圆所划出圆周长。

According to Descartes, this is just as certain as it is inherent in the idea of a circle that all points of the circle are equidistant from the center.

根据笛卡尔说法，这与圆所有点都与圆等距圆想法一样确定。

If a circle is rolling continuously within a shape, the distance travel by the circle center decreases by one circumference of the circle, making the total number of rotations N minus one.

如果圆在形状内连续滚动，则圆移动距离会减少圆一圈，使总转数 N 减一。

Take a circle rolling without slipping on any surface from a polygon to a blob, on the outside or the inside, the distance traveled by the center of the circle is equal to the amount the circle has rotated.

假设一个圆在任何表面上滚动， 从多边形到斑点，无论是外部还是内部， 圆移动距离等于圆旋转量。
