摘　　要：提出了三面顶点“流形”曲面立体完整画隐线图的标记理论和方法。在三面顶点曲面立体完整画隐线图中合法的节点型式共有69种,其中Y型节点有8种,W型节点有16种,S型节点有11种,V型节点有34种。对曲面立体完整画隐线图进行标记,能够判断其是否可能为“流形”曲面立体的投影,区分正确与不正确画隐线图。提出的完整画隐线图标记方法也适用于平面立体画隐线图。算例证明曲面立体完整画隐线图标记方法是正确、可行和有效的。A new labeling theory and method are proposed for the line drawings with hidden-part-draw for the three-dimensional manifold curved surface objects with trihedral vertices. Some rules for labeling are established. There are 69 kinds of possible junctions for line drawings, including 8 kinds of junctions for Y type, 16 for W, 11 for S, and 34 for V. By labeling line drawings for curved surface objects, two things can be judged： one is whether the projection of curved surface objects is manifold; another is whether the line drawings with hidden-part-draw is correct or incorrect. This labeling method can also be used for planar objects. The given sample shows that this proposed labeling method is correct.
