【Abstract】 The Green’s function in a medium in which the conductivity varies stepwisely across boundaries and keeps constant elsewhere is an analytic function of the conductivities of different regions.In this paper the Taylor’s expansion of the Green’s function is given.By sui-tablly choosing the point around.which the function is expanded,the convergency of the series is guaranteed.更多还原
