abstract: The paper presents the laboratory stand for measurement of the influence of the mechanical stresses and the electrostatic field on the resistance and the dielectric constant of grains. It was stated that resistance decrease vs. compressive force and increase vs. tension force. The compressive stress decreases while the electrostaticfield increases the dielectric constant of grain. |
