摘要
一般位置直线各投影与投影轴的夹角不等于空间直线对投影面的倾角α、β、γ。那么,二者之间有何内在关系?α、β、γ之间又存在什么关系呢?本文用数学的方法对其进行量化讨论。
There are inclucded angels between the surfaces trace lines of common place plane and projecting shafts, and at the sametime, there are inclinations between common place plane and projecting surfaces.this articles wili revolve around what relationships lie in these angles.
