空间两异面直线间距离求法及其CAI

Solution to Distance Between Interspace Lines and Computer Aid Instruction

空间两异面直线之间的距离求法 ,是高校画法几何教学中的难点。本文从画法几何和空间解析几何两个不同的角度 ,描述了空间两异面直线间距离的求法 ,并用CAI方法仿真了求解的全过程。该方法应用于教学 ,必将增加学生学习的兴趣 ,并将有助于扩充学生的知识面 。

It is a difficult point in teaching descriptive geometry to solve the distance between interspace lines.The paper describes the process of the solution from two different points of descriptive geometry and interspace analytic geometry. With the help of a CAI courseware in classroom teaching,students' interest is raised and the quality of teaching effectively improved.
