| 摘 要： | 所谓的计算机样条,是应用计算机绘图软件在已知结点上生成的一条可控形状的光滑平面曲线.计算机样条的数学形式是一组递推公式,避免了线性方程组的求解.由于圆曲线的双值性,使用解析法时需借助图解法,虽不很方便但可获得更高的精度.

| Abstract: | The test, so-called computer spline, is a slippery and controllable plane curve, generated on the known crunode by computer drawing software. The mathematic form of computer spline is a set of recursion formula which keep away from solution of inear equations. On account of double value of circle curve,analytical methods need to be usde with the aid of graphic methods,which is inconvenient ,but can obtain higher precision. |

| Keywords: | computer spline one by one circle curve interpolation recursion formula |
