《计量技术》84年第4期上刊登了梁开阳同志写的《多面棱体全组合测量误差中计划[VV]的一个公式》一文(以下简称《梁文》)。该文推导出的计算[VV]的公式虽然是正确的,但它还不是最简便的计算公式。本文的目的就是找出一个更简便的计算[VV]的公式(为了简便,本文与《梁文》相同的地方一般不再重述)。“定角全组合检定法”的误差方程式如《梁文》中的式(1)所示。被测角偏差△α_i的计算公式,定角偏差△β_(i+1)的计算公式分别
“Metering Technology” No. 4, 1984, published in Comrade Liang Kaiyang “multi-faceted prismatic combination of measurement error in a [VV] a formula” (hereinafter referred to as “Liang Wen”). Although the formula for computing [VV] derived from this article is correct, it is not yet the simplest formula. The purpose of this article is to find a simpler formula for calculating [VV] (for brevity, this article will not be repeated in the same place as Liang Wen). The error equation of “fixed angle combination test” is shown in formula (1) in Liang Wen. The measured angular deviation △ α_i formula, angular deviation △ β_ (i + 1) of the formula
