摘要

OIML r76是非自动称重仪器（NAWI）的推荐文件，被各成员国广泛接受。作为贸易使用的计量工具，NAWI为人熟知，且易于判断称重是否正确。在OIML r76中，有E0、E和Ec，通常Ec作为最终误差与最大允许误差的比较，Ec=E−E0，这是一个复杂的概念；但在基本思想上，误差看起来很简单，它等于指示值与标准值的差值。误差模型是本文讨论和研究的中心问题，旨在提出一种理论与实际应用相协调的修正误差计算方法。

Analysis and research on error calculation model of OIML R 76 and reality application

OIML R 76 is a recommendation file of non-automatic weighing instruments (NAWI), which is widely accepted by member countries. As an instrument for trade using, NAWI is known intimately and easy to judge weighing correct. In OIML R 76, there are

E_{0}

E

and

E_{c}

, usually

E_{c}

is as the final error compared with maximum permitted error,

E_{c} = E - E_{0}

, which are complex concepts; but in fundamental ideas, error looks simply, which is equal to difference value of indicating value and standard value. The error model is the central issue discussed and studied in this paper, aiming to propose a modified error calculation method that harmonises theory with practical application.
