根据我们使用名为FB-1的原型曲条天平的经验，BIPM设计并制造了1公斤重量的质量比较器。柔性带天平FB-2是全自动的，主要用于研究。在空气或真空中称量1公斤物品的可重复性始终比最好的刀口天平高出至少10倍。本文的目的是描述FB-2的设计和能力，借鉴已经发表的理论研究。最后，给出了FB-2的计算结果，说明了它的可重构性。
A mass comparator for 1 kg weights has been designed and built at the BIPM based on our experience with a prototype flexure-strip balance named FB-1. The flexure-strip balance FB-2 is fully automated and mainly used for research. It consistently achieves a repeatability of weighings in air or in vacuum of 1 kg artefacts at least ten times better than that obtainable with the best knife-edge balances. The aim of this paper is to describe the design and capabilities of the FB-2, drawing on theoretical studies already published. Finally, results obtained with the FB-2 are given to illustrate its metrological possibilities.
