摘　　要：计算机辅助教学(CAI)是综合应用多媒体、超文本、人工智能和知识库等的计算机技术,其在现代化的教学过程中发挥着重要的作用。本文以工程图学相贯线为例,重点探索两回转体相交所得相贯线的CAI教学设计。并针对两种重要的相贯线求解方法——表面取点法、辅助平面法,给出各自的CAI教学方案,从而有助于增强学生对相贯线产生及其求解过程的认识和理解,提高相贯线的课堂教学效率。Computer aided instruction(CAI)is a computer technology that integrates multimedia,hypertext,artificial intelligence,and knowledge base.It plays an important role in the modern teaching process.This paper takes the intersection of engineering drawings as an example to focus on exploring the CAI teaching design of intersecting lines obtained by intersecting two rotating bodies.In order to enhance the students'understanding and understanding of the generation of intersecting lines and their solution process,the two methods of solving the two important intersecting lines-the surface point selection method and the auxiliary plane method-were given.Improve the classroom teaching efficiency of the intersecting line.

关 键 词：计算机辅助教学 工程图学 相贯线 表面取点法 辅助平面法
