Mn and Ni at the core position have the effect of reducing the discharging energy, while away from the position it has the effect of increasing the discharging energy
Mn and Ni have the effect of reducing differential emission energy at the core position, while away from the position there is an effect of increasing differential emission energy
Mn and Ni can reduce the effect of differential energy discharge at the core position, and increase the effect of differential energy discharge at the far away position<br>
