计量学家
metrologist
- 大多数历史学家也曾对计量史学寄予厚望，希望通过它来完成历史的科学化。
Most historians also said to have great expectations, hope metrological historiography through to its completion of history science. - 历经多年，质量标准参照物——铂铱合金圆柱体的质量已略有减轻。 你倒不至于把浴室秤给扔掉，但计量学家就有得操心了。
The reference cylinder's mass has drifted slightly through the years—not enough to throw off your bathroom scale, but enough to bother measurement scientists. - 计量学家们正忙于用普朗克常数来重新定义“千克”，普朗克常数被认为是一项无法推翻的公式，就像光速一样（当然，这还有待欧洲核子研究委员会的进一步发现）。
Metrologists are busy trying to recast it in terms of Planck’s constant, a formula which is deemed cosmicly inviolate, as is the speed of light (pending further findings from CERN, anyway).
