【Abstract】 A fluorescence detection system is described in this paper. By means of thermal atomization and laser resonance excitation technique, the system can measure the lifetimes of atomic fluorescence of refractory metals and therefore the lifetimes of the atomic energy levels. The measured lifetime of Rul energy level [4d65s（6D）5p]7P₄⁰ is 70.4（±5%）ns.更多还原
