我国西北地区幅员辽阔,气压、温度变化显著,为了保证西北区域量值准确一致,从1988年以来,酉北地区计量协作组暨西北国家计量测试中心,连续四年组织了量值比对工作,已经完成了三等量块、二等洛氏硬度块0.001级标准电阻、二等标准活塞压力计、工业用光学高温计、一级平晶(φ60mm)
Northwest China has a vast territory, significant pressure and temperature changes. In order to ensure accurate and consistent values in the northwestern region, since 1988, the measurement coordination group in the northwestern China and the Northwest National Measurement and Testing Center have organized quantitative comparison work for four consecutive years, Has completed the third block, second-class Rockwell hardness of 0.001 standard resistance, second-class standard piston pressure gauge, industrial optical pyrometer, a flat crystal (φ60mm)
