摘　　要：为适应飞速发展的工农业生产和科学研究工作的需要,量子计量标准的研制取得了一系列新成果。在国际单位制(SI)的7个基本单位中,建立质量单位千克(kg)量子标准的工作则遇到了较大困难。经过30多年的努力,用硅球法或功率天平法建立质量量子标准的工作均取得了较大进展,将简要地介绍这些新成果。A series of achievements about quantum metrological standards were obtained to meet the requirements of the quick development of industry and agriculture, as well as scientific research work. Among the seven fundamental units of SI,the establishment of quantum standard of the mass unit kg faces many difficulties. During the past 30 years, the work to establish quantum mass standard based on the silicon ball and the watt balance attained obvious progress as described in this paper.
