摘要
本文系统地研究了E^n中几何元素的线束方程,由方程中的方向数分析几何元素对投影空间的相对位置和几何元素间的相对位置,规律性强.对于帮助人们认识多维空间,提供了有用的数学方法.
The line pencil equation for geometric elements in En is studied. From the direction number in the equation, the relative position between the elements and the projective space anp that between any two elements are analyzed. This relationship is found to be of good regularity and will be a useful mathematical method for facilitating an understanding of En and the mathematical space.
