1. A super Nernst function phenomenon in the relationship of photovoltage and pH value is reported.

2. Based on the general Nernst equation, thermodynamics model of the submonolayer equilibrium potential was set up.

3. This article discussed anodic oxidation mechanism of aluminium plate by means of electrode potential, Nernst equation, overpotential and so on.

4. These effects of adsorption conditions call be characterized by Nernst equation.

5. On the basis of biology, it deduces the relation between the high electrostatic field and the transmembrane voltage by the formula of nernst and the quantum tunneling effect.
