摘要： 在Hanai理论基础上对球壳粒子悬浮系的介电模型进行了模拟研究,通过用C++的复数类对理论公式的程序化,建立了介电谱的介电参数与体系内部相参数的关系.所得的解析解可方便地模拟介电弛豫谱依不同相参数的变化曲线,计算并分析了内部参数对介电谱的模式以及介电参数的影响因素.

Abstract: Asimulation study of suspension in spherical shell-structure was made on the basis of Hanai theory. An improved and intelligentized program for solving the tedious equations from Hanai theory has been written with C++ language and complex class, and been applied to the numerical calculations of permittivities and conductivities at different frequencies from 10 to 107Hz. The dependence of dielectric spec-troscopy on the inner parameters of the system was obtained by an example actualized in a microcapsule suspension. The results show that the patterns of the spectroscopy can be reflected qualitatively by the electric and structural parameters of the constituted phases of the system.

Key words: Dielectric relaxation spectroscopy, Spherical dielectric model, Hanai theory
