1.前言在校准标准砝码的质量时,对环境影响进行修正是必要的,因为标准砝码是用不同材料制造的,例如:铂铱合金,不锈钢。它们的质量通常是在空气中测量的,特别是由铂铱合金和不锈钢制做的1kg 砝码间的浮力修正值达到
1. Introduction When correcting the quality of standard weights, it is necessary to modify the environmental effects because the standard weights are made of different materials such as platinum-iridium and stainless steel. Their mass is usually measured in the air, especially the buoyancy correction value of 1 kg weight made of platinum-iridium alloy and stainless steel reaches
