摘要 使用滑动平均值，给出了铜中 keV 离子引起的尖峰的密度、温度和压力演化。选择了可视化的特定事件，因为它代表了离子束引起的混合的平均特征。讨论了熔融尖峰核心中势能和动能之间的平衡，强调了熔化潜热的作用。举例说明了通过冷凝吸附原子向尖峰补充热量。
Abstract Using gliding averages, the density, temperature, and pressure evolution in a keV-ion induced spike in copper is presented. The particular event visualized has been selected since it represents the average features of ion-beam induced mixing. Equilibration between potential and kinetic energy in the molten spike core is discussed, emphasizing the role of the latent heat of melting. Re-fueling of heat to the spike by condensing adatoms is exemplified.
