这些参数之间的变化关系符合直接碰撞导致非晶化模型，即每一个注入离子由于级联碰撞使表面局部的小区域非晶化。

The variation relations between these parameters are found to agree well with direct impact amorphisation model in which each projectileamorphises a logical region by cascade effect.

The molar volume is being changed a little bit trying to make things collide with each other, they can't occupy the same volume.

摩尔体积发生了很小的改变,如果你试图使气体分子间相互碰撞，他们不能占据同一个位置。
