由国防科工委长、热、力计量一级站和中国计量测试学会几何量专业委员会角度学组联合举办的全国角度计量测试技术基础知识讲习班,第一期于1985年7月15日至8月23日在北京举办。参加学习的有41个单位的47名学员。学习重点为圆分度检测的基本理论与方法,以及圆光栅、感应同步器、多齿分度台等基本测角
The first phase of the National Angle Measurement and Measurement Technology Basic Knowledge Workshop jointly organized by the National Defense Science and Industry Commission, the Thermal and Power Metric Station and the Angle Measurement Group of the Geometrical Professional Committee of China Metrology and Measurement Society, the first phase was held from July 15, 1985 to August 23 in Beijing. There are 47 students in 41 units participating in the study. The study focuses on the basic theory and method of roundness detection, as well as the basic angle measurement of round grating, induction synchronizer and multi-tooth indexing table
