1992年7月13日,我所的两项重点课题“1MN杠杆式力标准机”与“大质量计量标准”通过了由国防科工委标准计量局组织的鉴定。出席会议的专家、代表共计百余人。雷天觉学部委员主持了会议。代表们听取了两项课题负责人的研制总结报告,并观看了实物及操作表演。鉴定委员会认为“1MN杠杆式力标准机”一机三用,属国内外首创,且各单项(100kN力标准机、1MN杠杆式力标准机和10t电磁天平)的技术指标和性能均达到了国际先进水平。“大质量计量标准”课题,除完成了10t不锈钢砝码和200kg天平任务
July 13, 1992, the two key issues of our “1MN leveraged force standard machine” and “mass measurement standards” passed the appraisal organized by the National Bureau of Standards, Experts and representatives who attended the meeting totaled more than 100 people. Lei Ti Jue members presided over the meeting. The delegates listened to the research summary report of the two project leaders and watched the show of kind and performance. The appraisal committee considered that “1MN lever-type force standard machine” is the first one in China and abroad, and the technical indicators and performance of each single item (100kN standard machine, 1MN lever standard machine and 10t electromagnetic balance) have reached the international Advanced level. “Massive Metrology” project, in addition to completing the 10t stainless steel weight and 200kg balance mission
