摘　　要：说明了具有公共边的两个三角形的面积在Ｂｅｚｉｅｒ曲面片拼接中的作用；讨论了插值Ｂｅｚｉｅｒ曲面片ＧＣ￣１拼接的条件，给出了各参数之间关系的公式，并当网格分化为特殊情形时的简化形式．The role of areas of two adjacent triangles in the continuity of Bezier surfacepatches is represented, the GC￣1 continuity conditions about two adjacent interpolated Beziersurface pathes are discussed,and the relations of each parameter are given , especially whenthe triangullar meshes are regular triangles.

关 键 词：插值 BEZIER曲面 三角域
