摘要针对参数样条曲面变形或近似展开时变形或近似展开前后点的对应关系的确定问

题，提出了一种算法:根据参数样条曲面与其参数平面上点的一一对应关系，用参数平面将变形

或近似展开前后的曲面联系起来，通过由坐标反解参数和由参数正解坐标，建立起其上点的对

应关系。

-Abstract The deformation parameters of spline surfaces or near or near the commencement of deformation around the point to start the corresponding relationships to identify problems, propose an algorithm: According to the parameters of spline surface and its parameters-one correspondence between points on the plane, with the parameter plane will be deformation started around or near the surface linked by the anti-solution parameters and coordinates are solutions of the coordinates by the parameters and establish the correspondence between the points.
