摘　　要：在《机械制图》中对已知的两端圆弧或一端直线一端圆弧用第三段圆弧进行相切连接,采用的方法是几何作图的方法,在教学过程中发现,许多版本的教材中对几何作图时的条件描述不够详细,导致作图时会产生异议甚至无法按照要求完成作图。本文采用数学分析的方法,结合几何作图方法,在不产生歧义的情况下完成圆弧连接作图。In Mechanical Drawing,known arcs at both ends or straight lines at one end and arcs at one end are tangentially connected with a third section of arc,using the method of geometric drawing.In the teaching process,it is found that the conditions of geometric drawing in many versions of textbooks are not detailed enough,resulting in objections or even failure to complete the drawing as required.In this paper,the method of mathematical analysis and the method of geometric drawing are adopted to complete the arc joint drawing without ambiguity.

关 键 词：圆弧连接 数学分析 几何作图
