IUPAC 原子量与同位素丰度委员会于1985年8月31日至9月3日在法国里昂召开,主要结果是修订了34种元素的原子量,其新值列于附表,括号内数字指末位数的准确度。另外,对“原子量四位数表”(旧表见本刊1984年,3期,58页)作了32号元素锗 Ge 原子量的修订,新值为72.61(2),又作一项勘误,即41号元素铌 Nb 的原子量应为92.91。
The IUPAC Atomic Weight and Isotope Abundance Commission was held in Lyon, France from August 31 to September 3, 1985 with the main result of the revision of the atomic weights for the 34 elements, the new values for which are listed in the attached table, and the figures in brackets refer to the last digits Accuracy In addition, the atomic number of the four-digit atomic weight table (see the 1984 edition, 1984, No. 3, 58) made a revision of the 32 element Ge Ge atomic weight, the new value of 72.61 (2), also made an errata, That element 41 niobium Nb atomic weight should be 92.91.
