vacancy mechanism

The diffusion mechanism wherein net atomic migration is from lattice site to an adjacent vacancy.

一种扩散机制,这时候原子的净迁移过程是从晶格结点位置移动到邻近的空位中.

These results show that the ion beam mixing mechanism of Mo/ Si system is not vacancy diffusion and intra-cascade interstitial diffusion, and the thermal spike model also does not apply.

结果表明，以前的空位扩散机制、单级联间隙原子扩散机制和热峰模型都不能解释Mo/Si体系的离子束混合。

For the former case, it starts from the mechanism proposed by Iida, taking into account the influence of cation vacancy upon the energy levels and wave functions of Co2+;

前者从Iida提出的物理机构出发，考虑了阳离子缺位对Co~（2+）能级和波函数的影响；
