马余强 %A 李振亚 %J 物理学报 %D 1990 %I %X In this paper, starting from the relation between two distinct topological structure, we propose a simple self-consistent method based on the Maxwell-Garnett theory, in order to improve the Bruggeman's effective medium theory (mean-field-type approximation). We derive a general expression for the effective conductivity of a two-phase random composite system. The theoretical results on electric and thermal conductivity for some real materials are in good agreement with experimental data. %K 介质 %K 理论 %K 二元 %K 无规 %K 混合物系统 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=35F3E88D967E3FEB2C21D1F2A6627A00&yid=8D39DA2CB9F38FD0&vid=7C3A4C1EE6A45749&iid=38B194292C032A66&sid=D0E8F9CBDBE0070C&eid=788931E6318420A3&journal_id=1000-3290&journal_name=物理学报&referenced_num=2&reference_num=2
