摘　　要：应用矛盾的对立统一法则,分析了青铜器在整个生命周期中的腐蚀特点.结果表明腐蚀可分为服役期、埋藏期和出土后的加速腐蚀期三个阶段.在埋藏期逐渐形成了由腐蚀产物和表面层组成的高效氧电极和青铜电极组成的复杂的原电池腐蚀体系.重点讨论了青铜器出土之后,这一腐蚀体系被启动和加速的特点.提出了加速青铜器腐蚀的多孔氧电极催化机理.Based on the incompatible principle,the corrosion characteristic of bronze was discussed. The whole process could be divided into three stages including service period,burial period and accelerated corrosion period.In the second period,a complex system of original cell corrosion composed of high-performance oxygen electrode and bronze electrode might gradually formed. And the characteristics especially after the bronzes were unearthed of this corrosion system were discussed.A model was proposed to describe the process that porous oxygen electrode existed on the surface might catalytically facilitate the pitting corrosion of bronzes.
