Abstract

Biological mediums have both the conductor and the dielectrics properties. Free ions availability in the cells and tissue is due to the conductivity of these mediums. Dielectric properties of biological mediums and the value of dielectric permittivity are determined by the structural components and the phenomenon of polarity. Currently, in studying the processes occurring in the cells and tissue, in changing their physiological state as well as in investigating pathologic sates of biological mediums such diagnostic indexes as specific conductivity /spl sigma/ and dielectric permittivity /spl epsi/ are used. To determine these indexes the eddy current methods are used, which are characterized by high information density, safety and simplicity of realization. The given paper is aimed at the performance of theoretical investigations of the action of the specific conductivity and relative dielectric permittivity of biological medium on the insertion voltage of the eddy current converter (ECC).

生物介质参数对涡流变换器插入电压的影响分析

生物介质既有导体性质，又有介电性质。细胞和组织中自由离子的可用性是由于这些介质的导电性。生物介质的介电特性和介电常数值是由其结构成分和极性现象决定的。目前，在研究细胞和组织发生的过程，改变其生理状态，以及研究生物介质的病理状态时，常用的诊断指标有比电导率/spl sigma/和介电常数/spl epsi/。采用涡流法测定这些指标，具有信息密度高、安全、实现简单等特点。本文旨在从理论上研究生物介质的比电导率和相对介电常数对涡流转换器(ECC)插入电压的作用。
