电流密度对铸层表面形态有较大的影响。
表面原子层电荷密度越大，表面能越低。
The higher the average surface electronic density is, the lower the surface energy is.
低喷丸强度试件表面微裂纹大量萌生，密度非常高。
Crack initiation life is much longer than those of low shot peening pressure.
性能：表面耐磨，机械强度高，平整度高，密度均匀。
Property: scratches resistance, high mechanical, good flatness uniform density.
表面陷阱能级和密度的变化也会影响表面陷阱效应。
Also, energy level and density of the surface-trap will influence the surface-trap effect.
