近几年来,英国、美国、比利时、澳大利亚和苏联等国家的貭量計量部門,把各种不同材料的砝碼密度值,統一在某一个約定的数值上,即规定了砝碼材料的統一名义密度。这样就省略了砝碼检定时的空气浮力修正工作,节約了人力和时間。为了把这項措施在可能的情况下应用到我国的貭量計量工作中去,茲发表此文,望讀者广泛提出意見。以便提供国家科委計量局在“天平砝碼检定規程”修訂时参考。
In recent years, the measurement departments of Britain, the United States, Belgium, Australia, the Soviet Union and other countries have unified the weight density values of various materials on a certain agreed value, that is, the unified name of the weight materials density. This will omit the calibration of the air when the buoyancy correction, saving manpower and time. In order to apply this measure to our country’s metrological work wherever possible, this article is published in the hope that readers will make extensive comments. In order to provide the National Science and Technology Commission measurement bureau in the “balance weight verification procedures” for reference when amended.
