摘要
根据解析几何的原理创建了圆柱与圆柱轴线相交时,相贯线在公共对称面上投影方程的数学模型,讨论了在几种情况下相贯线的形状及特点.从而实现了将画法几何、计算机图形学和工程制图融为一体的教学模式.
Based on the principle of analytic geometry, the mathematical model of the projection equation of intersecting lines on the public symmetry plane is established. Some solution method of the line of cylinder and cylinder intersection, shape and their characteristics analysis are discussed, so that a kind of the teaching model and it included as the descriptive geometry, computer drawing and engineering drawing may be obtained.
