摘　　要：钚材料具有极其复杂的物理化学特性,关于钚材料从微观到宏观等各个角度的科学研究都是对当前科学和技术的挑战。关注钚材料的老化研究,综合分析了引起钚材料老化的3种机制,以及研究采用的方法、手段和取得的成果,为相关研究提供参考。Plutonium is the most important material for the nuclear weapon and nuclear reactor, but the metal is very complex in its physical behaves and chemical properties. The microscopic and macroscopic research of this metal is a challenge to the modern science and technology. In this paper, we focus on the research of plutonium aging mechanism, and the three mechanisms induced the aging of plutonium were presented. Methods and means, especially the results for the research are also presented to give some references to the related study.

关 键 词：钚 老化机制 衰变 表面腐蚀 相变不稳定性
