北大无线电系电真空物理数研室吴全德教授应211所的邀请,于1979年3月5日—11日来昆明讲学。吴教授是我国从事光电子发射研究的阴极电子学专家,多年来从事银—氧—铯光电阴极和三碱光电阴极的理论和实验研究,提出了银—氧—铯阴极的固溶胶粒理论,建立了银—氧—铯阴极固溶小胶粒光电发射的物理模型,比较圆满地解决了银
Professor Wu Quande, Department of Electrical and Vacuum Physics, Radio Department of Peking University, gave a lecture at Kunming on March 5 to 11, 1979 at the invitation of 211 Institute. Professor Wu is a cathode electronics expert engaged in photoelectron emission research in China. He has been engaged in the theoretical and experimental studies of silver-oxygen-cesium photocathode and ternary photocathode for many years and has put forward the theory of sol-sol particles for silver-oxygen-cesium cathode Silver-oxygen - cesium cathode solid solution of small particles of physical model of photoemission, a more complete solution to the silver
