A Measuring System for Cryobiological Dielectric Spectrum LIU Hai-yang CHEN Zhao-zhang XU Xiao-bin HUANG Yong-hong College of electrical and information engineering, Jiangsu university ,Zhenjiang 212013,China） 【Abstract】In this paper the Principle, circuit and designing process of a measuring system for cryobiological dielectric spectrum(CDS) is presented. We applied a data-collected card developed by krxic Inc, designed a VB
program and a PCB board, developed a measuring system for CDS successfully, which can be used to display and record CDS dynamically. As a part of project funded by NSFC, the successful development of measuring system for CDS will provide good condition for the research of dielectric spectrum.
