“切点法”求取正交柱锥相贯线极位点的误差分析

Error Analysis of the Extreme Point of the Intersecting Line Made by Cylinder and Cone with Their Axes Intersecting at Right Angle by Means of the Point of Tengency

用解析法分析了“切点法”所求取的正交圆柱和圆锥相贯线极位点所存在的误差，给出了影响误差的因素和误差变化趋势。

The error of extreme point of the line of intersection was analysed by an analytic method that obtained by cylinder and cone with their axes intersecting at right angle by means of the point of tengency,factors affecting the error and the tendency of its variation was given.
