| 摘 要： | Decades ago, he invented a cascade extraction theory and technique that have greatly facilitated the production of the so-called ＂industrial vitamins,＂ shifting China＇s role from a low-profit exporter of raw ores to the world＇s dominant supplier of separated individual rare earth compounds and metals in high purity. Now, long past retirement age, he is still actively engaged in the development of China＇s rare earth industry by calling for planned exploitation and resource conservation. Prof. Xu Guangxian （Kwang-Hsien Hsu）, 89, a CAS Member and laureate of the 2008 State Supreme S＆T Award, is among the most outstanding scientists of our time.
