摘　　要：利用积分方法构造了带双形状参数的C-B样条曲线基函数,这类曲线具有标准C-B样条曲线主要性质,如连续性、凸包性等;根据形状参数的不同取值可以整体或者局部调控曲线形状,由此生成的曲线与曲面,作为一种新的几何造型方法,可应用于CAD/CAM领域。A new class of basis functions was present to construct combines the main properties of the standard C-B spline curve. changing the values of the shape parameters. As a new geometric applied in CAD/ CAM. C-B spline curves with two shape parameters, This kind of curve The shape of such curves can be adjusted totally or locally by modeling method ,generating of such curves and surfaces can be
