测量金属表面生成氧化膜在电解质中的电位时,金属/氧化膜/电解质/参比电极构成了多电极体系,其中包括3个电池,由3个电池之间的关系、电池过程中所有的电化学反应、电荷传输步骤和化学反应步骤,导出电位的普遍适用的公式: E=E_a~0+sum from s=1 to 3|η_(t,s)|-1/(ne)v_7ΔG_7, E=E_c~0-sum from s=4 to 6|η_(t,s)|+1/(ne)v_8ΔG_8。当金属/氧化膜/电解质电池受到不同的步骤控制时,可以得到不同的简化公式。 When measuring the potential of an oxide film in an electrolyte on a metal surface, the metal / oxide / electrolyte / reference electrode constitutes a multi-electrode system consisting of three cells, the relationship between three cells, all the electricity in the cell Chemical reactions, charge transport steps and chemical reaction steps to derive the generally applicable equation for the potential: E = E_a ~ 0 + sum from s = 1 to 3 | η_ (t, s) | -1 / (ne) v_7ΔG_7, E = E_c ~ 0-sum from s = 4 to 6 | η_ (t, s) | + 1 / (ne) v_8ΔG_8. When metal / oxide / electrolyte cells are subjected to different steps, different simplified formulas are available.
