晶界作为缺陷阱，被认为可以吸收碰撞级联中产生的Frenkel缺陷。对于不同的晶界，其对缺陷的俘获强度和吸收机制有所差异。通过统计晶界附近缺陷的分布情况，计算晶界对缺陷的俘获半径

Grain boundaries, as deficiency traps, are thought to absorb Frenkel defects arising from collision cascades. For different grain boundaries, the trapping intensity and absorption mechanism of defects are different. By counting the distribution of defects near grain boundaries, the capture radius of defects by grain boundaries was calculated
