摘　　要：研究关于修改有理贝齐尔(Bézier)曲线的方法.通过控制点、权因子的单个及多个修改改变有理贝齐尔曲线的形状,在此基础上附加限制条件达到对有理贝齐尔曲线的精确修改.The change of method about rational Bézier curve is studied. First,through the change of single control point,right factor and the simultaneous,the shape of rational Bézier curve is changed. Second,restrictive condition is added to change the shape of rational Bézier curve.
