摘要
介绍平行双样测量值相对偏差计算方法。平行双样测量值相对偏差有3种计算公式,相关表述有4种,分别为平行双样相对偏差、平行双样相对误差、平行双样相对相差、平行双样相对允许差。相关规定出自不同行业和部门,既不统一又不规范,容易造成分歧。建议在国家标准的层面对平行双样相对偏差的计算公式及其表述加以统一规定,实现标准化、规范化。
The calculation method of parallel sample measurements relative deviation was introduced.There were three kinds of calculation formula of parallel sample measurements relative deviation,four related expressions,respectively of relative deviation of parallel samples;relative error of parallel samples;relative phase difference of parallel samples;relative allowable deviation of parallel samples.Related regulations from different industries and departments were neither uniform nor specification,and easy to cause disagreements.It is suggested that the calculation formula and its expression about relative deviation of parallel samples should be stipulated uniformly at the level of national standard,the realize standardization and normalization.
