| | In this paper,we discuss the theory of compasses constuctin. the conclusions of this paper are following: | | 为了使人们对圆规这一作图工具有更深刻的认识,集中研究了平面几何中的尺规作图公法。本文的结果指出了高斯关于等分圆周的定理中的直尺这一工具是多余的,只用园规就可以了;同时指出欧氏尺规作图公法中有几点并不真正独立。 | | 文摘来源 | | For solving regular polygon,the author presents a geometrograph which divides the circumference uniformly and arbitrarily; and derives an analytic expression. It is also proposed to calculate regular polygonal parts in designing and processing by way of solving triangles. | | 介绍任意等分圆周的几何作图法及所推导的解析表达式,提出用解三角形法解决正多边形零件在设计和加工中的计算问题. | | 文摘来源 | | This paper analyzes the effect of all kinds of approximate drawing on the precision of workpiece`s dimension, quantificationally by means of calculating the error in the way of geometrical construction which divides the circumference into parts and brings forward the principle that selects the dividing circumference`s lineation of the workpiece with reason. | | 通过对几何作图法等分圆周的误差计算,定量分析了各种近似画法对工件尺寸精度的影响,提出了合理选用工件圆周等分划线方法的原则。 | | 文摘来源 | |   | | << 更多相关文摘 |
