| 摘 要： | 提出用重影线法判断两重影直线的相对位置和求解一般位置直线与平面相交求交点判别可见性的新方法.笔者是从空间角度分析两几何元素的相对位置,阐述了空间重影两直线的投影特征和一般位置直线与平面相交平面内重影线的存在性及投影的表现形式,并应用这些规律,直接判断重影两直线的相对位置、直线与平面相交交点的求法和直线投影可见性的确定.

| Abstract: | A new method was put forward to find the intersection line and determine its visibility of general position lines and planes using overlapped projection lines.The overlapped projection of two lines projected on one plane is analyzed and the intersectional graphic position from the point of space is determined so as to find the intersect point and determine its visibility. |

| Keywords: | overlapped projection lines relative position intersection line visibility |
