摘　　要：随着我国成功加入WTO后,必将更加深入广泛地参加国际技术交流及产品贸易等活动;在这些活动中,重要的交流工具反而是我国原来使用很少的第三角投影图。为此,文章在介绍投影理论的基础上,着重研究了第三角投影法的投影原理、数学变换方法及程序设计思路,并探讨了现场读图时第三角投影图和第一角投影图的快速转换技巧等。International technology communication and production trade will be even more abroad after China enters into the WTO. During these activities,an important communicative tool is the third angle projection drawing which is seldom used in China. In this paper,the concept of projection is introduced,and the third angle projection principle,mathematic switching method and program design thought are investigated. The fast switching technique between the third angle projection drawing and the first angle projection drawing at spot is also discussed.
