摘　要:目前对于普通螺纹规中径的校准方法有很多,比如三针法、影像法、轴切法、侧规法和环规法等等。而对于一些大尺寸的特殊螺纹规（如锯齿形螺纹规）没有统一的方法,该文对这类特殊螺纹规的中径校准提出了一种切实可行的解决办法,并且在实际应用中得到了验证。[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]

Key words:serrated thread gauge; pitch diameter; calibration method

好东西，小尺寸也可以这样算吗
