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及不合理组合形式的确定条件.从而给出判定此类投影图方法,并举出应用实例.The question of constructing multi-combinator from the two existing projection views is studied. The projection character from two-projection drawing of three-dimensional combination can be constructed from the two-projection of combination on the basis of the point of projection type of body surface and relative position of borderline frame. The equation to determine quantity of multi-combinator＇s shapes is put forward. Thus the determination method for this type of projection drawing is educed. And some three-dimensional examples are also illustrated.
