| 摘 要： | 本文对相贯线两个相关的关键问题——趋势及极值点——进行了研讨,提出并通过示例说明相贯线弯曲方向及弯向的变化可通过比较曲线上点的斜率基本确定。本文还解决了两二阶回转面在公共对称面投影的特位点的作图法。

| Abstract: | In this paper, twe correlated critical problems on intersection of solids -trend and extreme value-has been researchecd. The bending diretion of intersection of solids has been illustrated and the bending direction varriation could be determined by comparing the slopes at different points on the curve. In addition a graphical method has been found, with it the point of special projecting a quadeic of revolution on the common symmetrical plane can be determined. |
