| 摘要: |
| 研究了两相邻B样条曲线近似拼接成1条B样条曲线的问题，基本出发点是寻找精确拼接两曲线的条件，然后通过约束优化目标，重新调整曲线的控制点以满足此条件；为了获得这样的曲线而不用多余的节点，提出了一种调整某1条后次曲线的后后个节点，且不改变其形状的新算法；同时讨论了更一般的曲线拼接问题，即让拼接曲线通过某些目标点。 |

| Abstract: |
| This paper explains the problem of approximate joining two adjacent B-spline curves into one B-spline curve. The basic idea of the approach is to find the conditions for precise joining of two B-spline curves, and readjusts the control points of the cu |
