摘　　要：针对组合体二个投影视图可构建多种组合体形状的问题进行研究,从体表面的投影类型及相邻线框相对位置出发,分析得出组合体二个投影图可构建多种三维形体的组合体二个投影图的投影特征,总结出多种组合体形状数量的确定公式。从而给出判定此类投影图方法,并举出一些三维形体的例子。This paper studies the question of constructing multi-combination from the exiting two views. The projection character that manifold two-projection drawing of three-dimensional combination can be constructed from the two-projection of combination is analyzed from the point of projection type of body surface and relative position of borderline frame. The equation to determine quantity of muhi-combination＇s shapes is put forward. Thus the determination method to this type of projection drawing is reduced. And some three-dimensional examples are illustrated also.

关 键 词：组合体 投影特征 数量 三维形体
