the surface charge density and the electric field strength in neutral purple soil were much higher than that in Latosol.(2) with the increasing of electrolyte concentration,the charge quantity and the surface charge density increased a little,and those in the Latosol increased higher than that in...
The surface charge density distributions are obtained by considering the skin effect and applying Gauss’ law during FEM calculations92. In all cases, a linearly-polarized light with the electric field polarization along the gap axis of the central dimer (x-direction) was used as the excitation ...
F is a force term, which in the present case represents the applied external electric field, i.e., F=ρE·E, where ρE is charge density of the solution. Inside the electric double layer ρE≠0, since there is an excess charge present; far away from the charged surface, where the ...
