Study on the whole conductivity of mixture
混合物整体电导率的研究

A conductivity definition for mixture is derived by solving the average for Ohm's law.An electric field intensity increment equation in mixture is derived by solving the average for the principle of conservation of electrical current.In terms of the conductivity definition for mixture,conductivity formula of mixture is obtained by solving the average for the electric field intensity increment equation in the same composition.The conductivity formulas for three kinds of mixture structure(series mixture,parallel mixture and isotropic mixture) are examples of the conductivity formula of mixture.It is concluded that the whole conductivity of mixture is the volume series of structure parallel of all composition conductivities and the whole conductivity.
