The Studies on the Eletrical Conductivities Performance of Particle Filled Composite

This paper induces alternate field of elastic theory into electomagnetics，from the first principle，sets up an integral equation of determining electric field in composite by border condition imitatingand Fourier analysis，further studies its electrical conductivities，theoretical result is identical with experimentalvalue. The method of this paper is not limitted by particle density and system structure，it opensa new way about studying the conductance of composite.
