effective conductivity การใช้

• *Fiori, I . Jankovic and Dagan G ., Effective conductivity of heterogeneous multiphase media with circular inclusions, Phys.
• Once the complex permittivity of the material is known, we can easily calculate its effective conductivity \ sigma _ e and dielectric loss tangent \ tan \ delta as:
• In spite of the viscosity of the acid, the effective conductivities of the and ions are high due to an intra-molecular proton-switch mechanism ( analogous to the Grotthuss mechanism in water ), making sulfuric acid a good conductor of electricity.
• In a system of Euclidean spatial dimension n that has an arbitrary number of components, the sum is made over all the constituents . \ delta _ i and \ sigma _ i are respectively the fraction and the conductivity of each component, and \ sigma _ e is the effective conductivity of the medium . ( The sum over the \ delta _ i's is unity .)
