对原子量、Ar（E）测定和其他同源数据的两年期审查导致下列元素的标准原子量发生变化：从到锌65.39 ± 0.02 65.409 ± 0.004氪83.80 ± 0.01 83.798 ± 0.002钼95.94 ± 0.01 95.94 ± 0.02镝162.50 ± 0.03 162.500 ± 0.001给出了标准原子量及其不确定度的更新表，这些不确定度是通过结合实验不确定度和地面变化来估计的。此外，本报告还载有一份更新的表格，列出选定放射性同位素的相对原子质量值和半衰期。与1997年公布的数据相比，同位素丰度值的变化相对较小，将在2003年对每种元素进行的主要审查中公布。在某些非地球物质中，许多元素有不同的同位素组成。本报告载有关于可能影响同位素丰度或原子量值的母核素的一些最新数据，供感兴趣的科学界参考。
The biennial review of atomic-weight, Ar(E), determinations and other cognate data have resulted in changes for the standard atomic weights of the following elements: From To Zinc 65.39 ± 0.02 65.409 ± 0.004 Krypton 83.80 ± 0.01 83.798 ± 0.002 Molybdenum 95.94 ± 0.01 95.94 ± 0.02 Dysprosium 162.50 ± 0.03 162.500 ± 0.001 Presented are updated tables of the standard atomic weights and their uncertainties estimated by combining experimental uncertainties and terrestrial variabilities. In addition, this report again contains an updated table of relative atomicmass values and half-lives of selected radioisotopes. Changes in the evaluated isotope abundance values from those published in 1997 are relatively minor and will be published in a major review of each element in 2003. Many elements have a different isotopic composition in some nonterrestrial materials. Some recent data on parent nuclides that might affect isotope abundances or atomic-weight values are included in this report for the information of the interested scientific community.
