| 摘 要： | 通过计算机编程,建立了几种典型金属的原子团晶体模型.应用实空间Recursion方法,计算了这几种金属在纯净状态下的费米能级与电子态密度.由此得出随着金属的费米能级的升高,其电极电位会随之下降.而电子局域态密度分布在高能区的金属易失去电子,进行氧化反应.

| Abstract: | Through computer programming,the paper has established radicel crystal models for several kinds of typical metals.Using the actual space Recursion method,it has calculated Fermi level of these metals under pure condition.We can conclude along with metal Fermi level elevating,its electrode potential is lowered.The metal is easy lose electron when the density of electronic state spread is high. |

| Keywords: | electrode potential fermi level density of electronic state Recursion method |
