两非回转二次曲面交线特殊位置点的研究

Special Points on Intersecting Line of Two Norotationtal Surfaces

对参与相交的两非回转二次曲面为椭园柱或椭园锥，其轴线处于一般位置、两曲面的迹线为园时的交线的特殊位置点的解法做了进一步地研究。此法作图较简便、准确，对解决工程实际问题具有实际指导作用。

A graphics method for determinating the intersecting line and specific positioning points of two elliptical cylinders or conic surfaces is proposed. Its validity is verified by illustrative examples. This method is characterized in simpilicity and accuracy. 
