The paper puts forth that the numerical model of actual forming part is reconstructed by RE and the surface is regarded as actual trimmed surface, then grids and nodes mapping relationship between design model and actual forming part is acquired through compelling deformation simulation, and the design trimming line is dispersed into points according to a certain precision and the projective points and the coordinate values of the intersection points of projective line on the grids formed by discrete points are calculated along trimming direction, the new coordinate values of projective points and intersection points of projective line after deformation are calculated based on the mapping relationship of grids and nodes, the deformed trimming line can be acquired through fitting the points into curve.

本文提出通过逆向工程技术重构出实际冲压件的型面并以此型面为修边后实际冲压件的型面，然后采用强制变形仿真的方法建立设计模型和实际冲压件重构模型的网格和节点映射关系。将设计修边线按一定精度离散成点，然后根据修边方向计算出各点在网格上形成的投影点和投影线交点，根据之前计算出来的网格和节点映射关系就可以计算出投影点和投影线交点在变形后的新坐标，将其拟合成曲线就可以得到变形后修边线的形状。

In order to improve the control performance, when the image distortion is too large resulting from camera obliquity, these parameters are transformed from image coordinate to robot coordinate through projective transformation, while parameters such as position and curvature are not necessarily provided.

为改善控制性能，当由于摄像机倾角较大而引起的图像畸变较大时，利用射影变换把参考轨线参数从图像坐标系映射到机器人坐标系，而无须提供位置、曲率等参数。

Firstly, the optimal order quantity is determined with the channel coordination the supply chain; then the paper designs a combined contract (Revenue-sharing and Two-part Tariff contract, RS-TT), namely, it takes revenue sharing contract and two-part tariff contract in the two transactions of the three-level supply chain to coordinate the supply chain, including two forms: and. It validates that RS-TT contracts can coordinate the three-level supply chain by choosing reasonable parameters.

it was a routine way for graph- drawing based on coordinate data in application software to program and graph processing,because from coordinate data to graph it is uniqueness.in hydrologic analysis,we calculated related data according to figure parameters,as using rainstorm isoline to reckon average rainfall in the river basin.through examples and analysis,the paper proposed methods for curve numerical translation and area calculation by vb.

在应用程序编制和图形处理的软件系统中由坐标数据可以绘出图形是常规的途径，但有曲线图形，要生成坐标数据，至今还没有通用的方法，因为由坐标生成图形是唯一的，而反过来由图形转换为数据是非唯一的。在水文分析计算时，有时需要根据图形参数进行有关数据的计算，如用暴雨等值线图计算流域平均雨给出量的时候。通过分析和计算实例提出了利用vb实现可满足使用要求的曲线数值转换和封闭图形的面积计算方法。
