The hour hand: the circle of a clock face is divided by 12 hours, so each hour is 1/12 of the circle, and since a circle is 360 degrees, each hour is 360/12 degrees, so the angle of the hour hand is calculated this way, but as you all have noticed, no analog clock's hour hand stands still exactly on the current hour number until an hour is passed.

时针：在时钟面圆除以12小时，所以每个小时的1 / 12圈，由于圆是360度，每一个小时是十二分之三百六度，所以时针的角度这种方式计算，但大家都已经注意到，没有模拟时钟的时针上的立场仍有当前小时一个小时，直到完全通过。

With China's reform, opening up and economic development, China has formed are many professional production on the regional situation, and raw materials distribution market, the focus on displaying products distribution market, the industry layout is very important in these regions all productive resources, technical resources , the market resources, and labor resources in a relatively concentrated form a well-some one hour economic circle, a half-hour economic circle in the economic circle many of the costs are lowest in the country, even the lowest in the world, if business investment with the regional advantages combined, the likelihood of success will be greatly enhanced.

随着我国改革开放和经济发展，现国内已形成就了许多专业生产区域的格局，而原料集散市场、产品的集中展示集散市场，对行业布局非常重要，在这些区域里所有生产资源、技术资源、市场资源、劳动力资源相对集中并配套，形成了一些一小时经济圈，半小时经济圈，在这一经济圈内许多费用都是国内最低的，甚至是世界最低，如果企业投资能与地区优势相结合，成功的可能性也将大大提高。

In this paper,the mechanism of circle existing in nature is discussed,the circle contribution to mathematics is analyzed,a design of limit circle model for sustainable development for economics and society is put forward.

A novel no touch measuring method for traditional products was put forward and a precise model of Direct Linear Transform was presented for the aberration in the images occurred at every turn. Rectangle mark tag and location parameter are no longer needed in this algorithms. A method of tolerance reckon by curve equation was also provided. In order to raise the operation speed Hough circle detection method was improved. In the meantime circle detection method to images with more than one circle was applied, so that the concentricity calculation is possible.

论文的创新点是，提出了传统机械产品的非接触式测量方法，特别针对图像采集环节最容易出现的畸变现象，提出了一种严密的直接线性变换模型，该算法既不需要在影像上有框标，也不需要有摄影机内外方位参数的起始近似值，具有显著优点；提出了利用曲线的方程来确定公差的方法，对传统的Hough圆检测方法进行了改进，提高了检测速度，同时将圆检测用于存在多圆的图像，使多圆的同心度检测成为可能。

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。

Inscribed polygons are used to approximate a circle, and the number of line segments compose the polygon is detemined by the radius and its image of a circle.
