图1. 能量30 keV沿方向[235]的初级离位原子(PKA)产生的Frenkel缺陷对随时间的演化

Fig.1. The number of Frenkel pairs induced by 30 keV PKA moving in [235] direction as a function of simulated time (Insets show the simulated snapshots of local structures near the cascade center, t—the time of simulation, black lines in insets show the size of the vacancy zone, PKA—primary knock-on atom)
