| 摘 要： | 在求解异面直线间的距离问题时，一般采用换面法。作图过程有些复杂，笔者在解决此类问题时，巧妙地利用重影点，并通过建立三维模型用简单的方法得出结果。增强了学生的空间想象能力从而调动了学生学习制图的积极性。

| Abstract: | In solving the linear distance between different face problems, generally use the Exchange Surface. Some complicated mapping process, the author in resolving such issues, the clever use of ghost points and three-dimensional model through the establishment of the outcome of a simple way. Enhance the ability of students to mobilize the imagi-nation of space for students to learn mapping initiative. |
