摘　　要：通过将一般有理参数形式曲线转化为有理Bézier曲线表示,有理参数多项式曲线的拼接问题,也可以随之转化为有理Bézier曲线的拼接.研究了有理Bézier曲线的拼接问题,给出了两条邻接任意次有理Bézier曲线间G1和G2连续条件.The joining problem between rational parametric polynomial curves can be converted to the joining between rational Bezier curves,by converting a general rational parametric curve to a rational Bezier curve. The joining problem between Rational Bezier curves is researched and the continuous condition of G1 and G2 for two adjacent random rational Bezier curves is given.

关 键 词：有理参数曲线 有理BEZIER曲线 拼接 连续
