本刊２００１年第８期“一种垂直度测量方法”（下简称《方法》），我们读后，有不同的看法，特提出与广大读者及作者共同商讨。《方法》中写到“其最大与最小读数误差即为被测件的垂直度误差。”我们认为不确切。原因是宽座角尺为标准量具，尺的长度与工件被测要素的长度不可 We published in 2001 No. 8 “a measure of verticality” (hereinafter referred to as “method”), we read, have different views, especially with the majority of readers and authors to discuss. “Method” wrote that “the error between the maximum and minimum readings is the vertical error of the DUT.” We think it is not clear. The reason is that the wide-angle square as a standard measuring tool, the length of the ruler and the measured length of the workpiece can not be
