你刊81年第2期刊登的梁春裕同志《对现行圆分度器全组合检定法的探讨与改进》一文中,有如下的结论:用“定角代替法”计算得出的被测角偏差X_(定i)与用“被测角偏差算法”计算得出的被测角偏差X_i具有相等的精度。我认为这个结论是错误的。按照梁春裕同志的文章(以下简称《梁文》)解释,所谓“定角代替法”,就是如果使各定角偏差值恰好等于各被测角偏差时,则可用求定角偏差代替求被测角的偏差。而且各测回第一个测值为零时,《梁文》即认为各定角偏差已恰好与各被测角偏差相等了。
In the article entitled “Discussion and Improvement on the Current Round Indexer Combination Test Method” published by You Liang Chunyu published in Issue 2, Issue 81, No. 2, we have the following conclusions: The measured angular deviation calculated by “fixed angle substitution method” X_ ( Set i) Equivalent accuracy to measured angular deviation X_i calculated using the Measured Angle Deviation Algorithm. I think this conclusion is wrong. According to Comrade Liang Chunyu’s article (hereinafter referred to as “Liang Wen”), the so-called “fixed angle instead of law” is that if the fixed angle deviation value is exactly equal to the measured angular deviation, you can use the required angle deviation instead of seeking measured Angular deviation. And the first test measured back to zero, “Liang Wen” that the fixed angle deviation has been exactly equal to the measured angle deviation.
