摘要：

Measurements of isothermal (T = -28 degrees C), high-pressure behaviour (up to 270 MPa) of complex electric permittivity in supercooled glycerol are presented. The observed peaks of alpha relaxation in absorption curves show increasing relaxation time tau with increasing pressure. The behaviour of tau can be reproduced by the pressure version of an Arrhenius relation or by a modified Vogel-Fulcher-Tammann equation. The data obtained can be superimposed by applying the scaling form used by Dixon et al 1990 Phys. Rev. Lett. 65 1108.
