摘　要:目前對于普通螺紋規中徑的校準方法有很多,比如三針法、影像法、軸切法、側規法和環規法等等。而對于一些大尺寸的特殊螺紋規（如鋸齒形螺紋規）沒有統一的方法,該文對這類特殊螺紋規的中徑校準提出了一種切實可行的解決辦法,并且在實際應用中得到了驗證。[著者文摘]

The calibration method research on pitch diameter of large-size serrated thread gaugeZhang Bo Qu ChaoqingShanghai Institute of Measurement and Testing TechnologyAbstract:Currently,there exist many calibration methods for pitch diameter of common thread gauge,such as the three-needle method,image method,axis cutting method,the side-lay method and the ring method and so on.However,there is no uniform method for some largesize special thread gauge（e.g.serrated thread gauge）.This paper presents a practical solution for such pitch diameter calibration of special thread gauge,which has been veri？ed in practical application.[著者文摘]
