1984年10月25日至26日,“约瑟夫逊电压标准”技术鉴定会在北京召开。参加会议的有国家计量局、中国科学院物理研究所、中国计量科学研究院、成都计量测试研究院、高等院校及中央各部所属研究所、生产厂与计量部门等22个单位54名同行专家。代表们对技术资料进行了审查,对系统技术指标进行了测试,并对系统技术性能进行了鉴定。“约瑟夫逊电压标准”由五部分组成:一、直流测量系统;二、约瑟夫逊结;三、微波与杜瓦系统;四、偏流与显示系统;五、低温系统。用此测量系统和中国计量科学研究院提
October 25, 1984 to 26, “Josephson voltage standard” technical appraisal will be held in Beijing. Participants at the meeting included 54 experts from 22 institutes including National Bureau of Metrology, Institute of Physics, Chinese Academy of Sciences, China Institute of Metrology, Chengdu Institute of Metrology, Institutes of Higher Education and Institutes affiliated to the Central Government, manufacturing plants and measurement departments. The delegates reviewed the technical data, tested the system’s technical indicators, and identified the technical performance of the system. “Josephson voltage standard” consists of five parts: First, the DC measurement system; Second, Josephson junction; Third, the microwave and Dewar system; Fourth, bias current and display system; Fifth, the low temperature system. Use this measurement system and China Institute of Metrology mentioned
