摘　　要：高等数学教材中关于二次曲面形状的讨论都采用截痕法.教学中引入直纹面概念,可为建筑施工专业的学生密切联系工程实际提供理论依据,收到较好的教学效果.The method of section is usually adopted in the discussion of quadratic surface in the teaching of college maths. Then a new concept of ruled surface is introduced to the teaching so that it provides a theretical basis for the construction-major students. The new method enables the students to combine theory with practice and it is very beneficial to them.

关 键 词：二次曲面 直纹面 单叶双曲面 双曲抛物面
