摘要
运用几何原理．对三沟尺的测量原理进行了分析，在此基础上对T3形（凸三边形）产品的内切圆特性进行分析．得出三沟尺测量T3形（凸三边形）产品内切国直径的正确方法．
The measuring principle of V-shape anvil micrometers has been analysed by geometricaI method. Bssed on the proper-ties of inscribed circle of T3 shaped(convex triangle)products have been examined. The correct method of measuring the di-ameter of inscribed circle of T3 shaped(convex triangle) products has been got.
