摘　　要：本文采用EAM势,通过分子动力学方法模拟了机械脉冲对金属铜从晶态到非晶态转变的影响。计算结果表明,在机械脉冲的作用下,转变温度随着机械脉冲的个数、幅度的增大而减少。With the Molecular Dynamic Simulation and the Embedded Atom Method（EAM）, the paper simulates the influence of the mechanical pulsing with different configurations on the transformation of Copper from crystalline state to the non-crystalline state. The result shows that the transformation temperature decreases as the mechanical pulsing number and the deformation increase.
