方圆过渡接头展开图的简化画法

Simplification of expanded drawing of square-and-circle transition connection

从微分几何短程曲率的定义分析出发 ,给出了方圆过渡接头展开图的一种简化画法 .先画出与之对应的圆锥面的展开图 。

Gn view of the difinition of calculus geometryical short distance curvature, the paper preseufs the expanded drawing simplification of square and circle transition connection. First of all, based on painting the exaned drawing of corresponding cone surface the auther has brought out the expanded drawing of the transitional connection conveniently.
