| 摘 要： | 利用传统的3次样条插值算法,可以得到经过确定控制点的光滑曲线,但是只能够得到1条曲线.传统算法的局限性影响了它在工程中的应用,特别是在印刷领域中的应用.为了解决上述问题,提出了改进算法.通过新的算法,得到了不同于原曲线的新的拟合曲线,拓展了3次样条曲线在工程中的应用范围.

| Abstract: | By traditional way,it can be get a velvet curve that passes thought the reference points which are confirmed,but it just can be get one curve insufficiency.Spline curve has its advantage compared with others curve,so it is used spline curve to solve problems in application,and put forward a ameliorated algorithm base on traditional algorithm,so it can be get a new curve that has the same reference points as old curve.By this way,it is colonized spline curve’application on practice work. |

| Keywords: | interpolation spline curve fitting slope |
