《节距法测量不直度和不平度的精度分析》一文(载一九七七年《计量工作》专刊)是笔者对不直度、不平度测量方法的精度进行分析的初步尝试,其目的无非是抛砖引玉,以期取得同志们的批评和讨论,共同总结一种较为完善的分析方法。笔者在《全国形位误差测试技术交流会》上读了湖南省计量局李元锴等同志写的《关于不直度、不平度误差的测量和测量误差的分析》一文后,颇受启发和教益,通过学习和理解,认为本人写的一文中,存在 “Pitch method to measure the straightness and roughness accuracy analysis,” a text (including “measurement work in 1977”) is the author of the straightness, unevenness measurement accuracy of the first attempt to analyze the purpose Is nothing more than throwing bricks to attract comrades in order to obtain commentary and discussion, to sum up a more comprehensive analysis. After reading the article entitled “Analysis of the Measurement and Measurement Errors of Intolerance and Roughness Errors” written by Comrade Li Yuanli of Hunan Provincial Bureau of Metrology on “The National Conference on Shape and Position Error Testing Technology”, I got some inspiration and lessons. Through learning and understanding, I think there is a text I wrote
