| 摘 要： | 研究带有表面层的介质球颗粒与另一线性介质颗粒无规混合的有效电导率．对于带有表面层的球颗粒可以等效成一个不带表面层的实心球颗粒与同一介质颗粒无规混合，等效后其实心球颗粒的半径等于原表面层的半径．利用Ｋｅｌｌｅｒ的倒易定理（ＲＴ），得到系统的有效电导率，其结果与有效介质近似（ＥＭＡ）所得结果基本一致．

| Abstract: | The effective conductivity of composites system which is composed of coated granular spherical dielectric mixed with a linear granular dielectric randomly was investigated. The system can be replaced by solid granular spherical dielectric and radius equal to radius of the original surface layer, using Keller reciprocity theorem(RT), the effective conductivity of composite materials are obtained, the results agree with effective medium approximation (EMA). |
