Electric FieldSurface Charge DensityPotentialElectric Intensity为了研究高压输电线路周围的电场分布,本文提出了基于面电荷密度的计算方法。该方法将每个子导线的表面进行剖分,以各个节点的面电荷密度作为变量,并利用线性插值来表示弧段的电荷密度,然后根据电磁场理论建立线形方程组来求解各个节点的面电荷密度。最后,本文用...
A dielectric cylinder with a given surface charge density is immersed in electrolite. The electrolite is treated via the two-dimensional nonlinear Poisson-Boltzmann equation. In the case of single-line charge located on the cylindrical surface, analytical expressions for the electric field as well ...

facet by measuring the surface voltage and charge density. The larger the exposure ratio of the (001) facet, the stronger the internal electric field and the higher the efficiency of charge separation and transfer. Regulating the internal electric field of BiOCl controlled by crystal facet design ...
Hi, I don't know if I have calculated the electric field correctly in task a, because I get different values for the Poisson equation from task b The flow of the electric field only passes through the lateral surface, so ##A=2\pi \varrho L## I calculated the enclosed charge as foll...
