摘要
把三次样条插值函数表示成三条直线的加权调配形式,并以此为基础提出一种张弛性样条表达式。此方法几何意义清晰,求解方便,曲线调节范围大,地图绘图效果优于张力样条法。

In this paper, cubic spline interpolation function is expressed as a form adjusted with three weighted lines, and on this basis a new lax-tense spline has been developed. This new spline method possesses clear geometric meaning, simple computation and a wide range of controllable curve drawing. So it is more effective than tension spline in carto graphic application.
