| 摘 要： | 利用有效介质理论导出了二元无规混合物的有效介电常数的普适计算公式。并且从二元无规混合物的两种拓扑结构出发，用自洽的方法改进了该二元无规混合物的有效介电常数计算公式。用该理论分析了金属微粒绝缘介质的远红外吸收和油水两元混合物的有效介电常数，与实验结果比较符合

| Abstract: | A general expression for the effective dielectric constant of a twophase random composite system was derived by using effective media theory. With consideration of the relation between two distinct topological structures, a simple selfconsistent way is used to improve this expression. The theoretical results on farinfrared absorption in small metal particleinsulator composite and the dielectric constant of oil/water twophase random composite system are in good agreement with experimental data. |
