摘　　要：就立体表面上作图即取点、求作截交线、相贯线的教学内容、学生一听就懂,但一遇到较复杂的实际问题就常常无从下手;且在教学中占用课时多等问题进行分析和探讨,提出了将立体表面上找点、求作交线、相贯线等内容进行适当地集中的讲授方法。实践表明,该方法不仅可以帮助解决上述存在的问题,还能提高教学效率。The three-dimensional mapping that is to take point on the surface, seeking for intersecting lines, intersecting lines of teaching content, the students one to understand, but a more complex practical problems encountered was often impossible to start with; and take lessons in teaching more analysis and discussion of issues, put forward a three-dimensional points on the surface to find, seek for intersecting lines, intersecting lines, etc. as appropriate to focus on the method of instruction. Practice shows that this method can not only help solve these problems, but also to improve teaching efficiency.

关 键 词：立体表面 截交线 相贯线 教学方法
