本刊1983年第9期刊登了巫云龙的《直线度误差测量中的一种方法》一文(下称原文)后,收到了北京夏扬的《也谈导轨直线度误差测量和计算——兼与巫同志商榷》一文(下称夏文)和南宁李南山的来信。以后,巫云龙又写了《再谈直线度误差测量》一文(下称巫文)。编者对上述文章的论点进行比较后,认为主要分歧是对国家标准的定义和检测方法认识不同,而不是学术上的原则问题。本着“百花齐放、百家争鸣”的方针,现将两种看法的主要内容综述于下,以期有进一步的认识。一、关于在计算“直线度误差值”时,应按误差曲线的最小包容线间垂直距离计,还是应
This issue published in 1983 issue 9 of Wu Yunlong’s “straightness error measurement method” article (hereinafter referred to as the original), received Beijing Xia Yang’s “Talk about the straightness of the rail error measurement and calculation - Discuss with Witch Comrade ”(Xia Wen) and Nanning Li Nanshan letter. Later, Wu Yunlong wrote another article titled “Measuring the Straightness Error” (hereinafter referred to as Malay). Comparing the arguments of the above article, the editor believes that the main differences are the different definitions of national standards and testing methods, rather than academic issues of principle. In line with the policy of “letting a hundred flowers bloom and a hundred schools of thought contend,” we will now summarize the main contents of the two views for the purpose of further understanding. First, on the calculation of “Straightness error value”, according to the error curve of the minimum inclusive line vertical distance meter, or should
