The result also reveals that B-spline model performs better than other models integralively in precision of fitting prices, curvesmoothness and stability.
样条法在利率期限结构的拟合精度、曲线光滑性及平稳性方面的综合效果最好。

Adopting this method, we can not only improve the smoothnessof filtering curve but also approximately preserve the shape of original function.
应用这种方法不仅可以改善滤波特性曲线的光滑度，还可近似地保持原函数的形状。

The result obtained decreases the influence produced by accidental elements, which guarantees the smoothnessof the curve, and has great use in trend analysis.
