光透法是一种基于沉降原理,当一束平行光透过悬浮液时产生的光的衰减进行粒度分布的测量方法。 由国家标准总局和冶金部标准化研究所授命上海钢铁研究所负责起草的金属粉末粒度分布的测定—光透法国家标准(草案),已于八四年十一月十九日在北京由北京钢铁研究总院、北京有色金属研究总院、中南矿冶学院等十八家协作单位参加
Light penetration is a method of measuring particle size distribution based on the principle of sedimentation, the attenuation of light generated when a parallel beam of light is transmitted through a suspension. By the State Administration of Standards and Ministry of Metallurgy Institute of Standardization Shanghai Iron and Steel Research Institute responsible for the drafting of the determination of the particle size distribution of metal powder - the light through the French national standard (draft), was November 19, 1984 in Beijing from Beijing Iron and Steel Research Institute, Beijing Nonferrous Metal Research Institute, Zhongnan Mining and Metallurgical Institute and other 18 cooperative units to participate
