基本物理常数的CODATA推荐值:2006
CODATA Recommended Values of the Fundamental Physical Constants: 2006
摘要:
本文给出了科学技术数据委员会(CODATA)推荐的2006年国际通用的物理和化学基本常数和换算因子的自洽集合。此外,它详细描述了常数值的调整,包括根据最小二乘分析的结果选择最后一组输入数据。2006年的调整考虑到了2002年调整中所考虑的数据,以及2002年12月31日(该调整的截止日期)至2006年12月31日(新调整的截止日期)期间所掌握的数据。新的数据大大减少了许多建议值的不确定性。2006年的数据集取代了以前推荐的2002年CODATA数据集,也可以在万维网physics.nist.gov/constants上找到。
英文摘要:
This paper gives the 2006 self-consistent set of the basic constants and conversion factors of physics and chemistry recommended by the Committee on Data for Science and Technology (CODATA) for international use. Further, it describes in detail the adjustment of the values of the constants, including the selection of the final set of input data based on the results of least-squares analyses. The 2006 adjustment takes into account the data considered in the 2002 adjustment as well as the data that became available between 31 December 2002, the closing date of that adjustment, and 31 December 2006, the closing date of the new adjustment. The new data have led to a significant reduction in the uncertainties of many recommended values. The 2006 set replaces the previously recommended 2002 CODATA set and also may be found on the World Wide Web at physics.nist.gov/constants.
