| 摘 要： | 本文主要介绍任意平面曲线回转面正轴测投影外形线的计算机生成方法。本方法对规则曲线回转面和不规则曲线回转面分别采用“一次逼近”和“二次逼近”的方法加以处理，不但可以避免大量的数学推导和运算，而且使不规则曲线回转面外形线的绘制成为可能。

| Abstract: | A new method is introduced in this article which is produced by the computer for the contour curve of the orthographic axonometric projection of the revolved surface on a plane curve. It handles the regular and irregular curve re-volved surface in two different ways:the ilnear approach for one and the quadratic approach for the other.It not only can avoid a large amount of mathematical for-mulas and calculation,but aiso mak e it possible for the contour curve of the re-volved surface on an irregular curve to be drawn. |
