摘　　要：叙述了触点的分合过程,说明了熔桥产生和电弧引燃的原因;介绍了直流条件下触点材料的转移机理,包括熔桥转移和极性转移;还介绍了影响电侵蚀的多种因素,例如:电气参数、机械参数、触点材料、环境因素等。The makeing and breaking processes of contacts were recounted. The cause of bridge formation and arc igniting were illuminated. The mechanism of material transfer under DC, including bridge transfer and polarity transfer were introduced. And factors affecting electric erosion, such as circuit parameters, mechanical parameters, contact materials working surroundings, etc., were also introduced.

关 键 词：电侵蚀 材料转移 触点材料
