我国第一台“50MN(5000tf)力源”,1986年12月下旬在成都由国家计量局主持正式通过技术鉴定。这是一台大型高精度力源装置,是国家计量局为适应我国工业、国防和科学技术发展的需要,列为“六五”期间计量科研的重点攻关项目,由中国测试技术研究院负责,在太原重型机器厂、太原矿山机械厂和第二重型机器厂等单位协作下研制成功的。
China’s first “50MN (5000tf) power source” was officially approved by the National Bureau of Weights and Measures in Chengdu in late December 1986. This is a large-scale high-precision force source device, which is the need of the National Bureau of Weights and Measures to meet the needs of China’s industrial, national defense and scientific and technological development. It is listed as a key research project for measurement and scientific research during the “6th Five-Year Plan” period, and is responsible for the China Institute of Testing Technology. Taiyuan Heavy Machinery Plant, Taiyuan Mining Machinery Plant and the second heavy machinery factory and other units successfully developed.
