定向概念在空间几何元素综合分析中的应用

Directional Concept Apply in the Syntheticai Analysis of Soatial Geometry Element

在进行空间几何元素相对关系的综合分析过程中,引入定向概念,然后按先定向,再定位,后量度的思路解决问题。

In the process of synthetical analysis to the relative relation in the spatial geometry element, the directional concept is introduced, the problem that is to be solve according directional and determine position, and finally measurement.
