【摘要】 为了向国际计量局提供SI单位的2e/h值,参加国际平差,1988年4月国家计量局和中国科学数据委员会组织了测试。本文给出了测试结果和国际平差结果,我国测试值与国际平差值仅相差4×10^-8。国家技术监督局决定采用航空航天部二院二○三所研制的2e/h测量系统作为国家临时电压自然基准。更多还原

【Abstract】 In order to submit the value of 2e / h for the SI Unit to BIPM and partici- pate in international adjustment, National Bureau of Metrology （NBM） and China Com- mittee on Data for Science and Technology （CODATA） set up a group of determined 2e/h in April 1988. The result of determination and international adjustment is given in this paper. The difference between two values is only 4×10^-8. The National Monitoring Bureau of Technology （NMBT） has decided that the 2e/hmeasuring system developed by Beiging Instituce of Radio measurement and metrology for use as a temporary natural voltage reference.更多还原
