摘　　要：讨论了三角域上ｍ次Ｂéｚｉｅｒ曲面片与矩形域上ｎ×ｌ次Ｂéｚｉｅｒ曲面片在公共边界上的光滑连接条件，并给出了ｍ＝３。Gives the necessary and sufficient conditions for smoothness between two adjacent Bézier surface patches,which are triangular patch of degree m and rectangular patch of degree n×l.From these conditions,we deduce simple representions of m=3,n=l=2.

关 键 词：曲面拟合 样条函数 几何连续 光滑连接
