前言本刊1981年第2期刊登了梁春裕同志“对现行圆分度器全组合检定法的探讨与改进”一文,以严密的数理逻辑推导出“定角偏差算法”与“被测角偏差算法”具有同等的精度,得出“定角偏差算法”可以用来代替“被测角偏差算法”的结论;从而寻求出一种简便的算法。 Preface The second issue of the journal published in 1981, Comrade Liang Chunyu “on the current circular indexer combination of test methods to explore and improve,” one article, with rigorous mathematical logic derived “fixed angle deviation algorithm” and “measured angle deviation algorithm” has The same precision, come to “fixed angle deviation algorithm” can be used instead of “measured angular deviation algorithm” conclusion; thus finding a simple algorithm.
