两线束对应构成的高阶曲线

HIGHER ORDER CURVE FORMED BY TWO PROJECTIVE LINE BUNDLES

以两射影对应直线交点的轨迹是二阶曲线为基础，研究了平面高阶曲线的形成方法，推导出了高阶曲线的参数方程，并利用计算机绘出了三阶和四阶曲线。

This paper studys the forming way of plane higher ordercurves based on that the trajectory of point of intersection of twoprojective corresponding lines is quadratic curve. It gives parameterequations of higher order curve, and draws three and four ordercurves.
