PROCEDURE TO CONDUCT HEAT-STIMULATED CURRENT SPECTROSCOPY OF DIELECTRIC MATERIALS

摘要

FIELD: analysis of dielectric materials. SUBSTANCE: in compliance with procedure specimen of analyzed dielectric material is placed between two electrodes, cell with specimen is positioned in zone of linear heating, required heating parameters are set by means of digital controller, weak currents emerging with relaxation of electret charge are generated, they are amplified with the help of amplifier-converter, currents are fed into personal computer based on circuit of analog-to-digital conversion, current spectra are observed visually, measurement results are stored in electron form with use of software oriented on graphical interface of user that provides possibility of presentation of measured value in the form of time diagram and execution of chronology of measurements. Computer processing of obtained data enables key parameters characterizing electret effect to be computed. EFFECT: enhanced adequacy of spectrum. 2 dwg
