文中给出了带两个形状参数的四次均匀B样条基函数,由其构造的样条曲线可以通过改变形状参数λ,μ的取值调整曲线的形状,其中参数λ控制整条曲线位置,参数μ对曲线作局部调整。
文中給齣瞭帶兩箇形狀參數的四次均勻B樣條基函數,由其構造的樣條麯線可以通過改變形狀參數λ,μ的取值調整麯線的形狀,其中參數λ控製整條麯線位置,參數μ對麯線作跼部調整。

The paper constructed the basis function of fourth degree uniform B-spline with double shape parame-ters. The shape of the constructed spline can be adjusted by changing the shape parameter λ,μ value. The whole curve position is adjusted by changing the parameter λvalue. The curve is locally adjusted by changing the parameter μ value.
